  I purchased from Monster Transmission on September 17, 2024, for my 2015 Chevrolet Tahoe. The first transmission sent was determined to be faulty and was replaced. Unfortunately, the second transmission is also defective. Since the initial purchase, I have been without reliable transportation, with my vehicle only being operable for approximately two weeks. I have incurred ongoing expenses from rental vehicles, which is unacceptable. The driveshaft included is not compatible, and if the transmission was sent "as is," the required output shaft/driveshaft yoke seal should have been included - but was not. I was told that they gave me permission to get it repaired and my warranty would stay in place at my cost. My truck has now been having issues since the first transmission was placed in Sept. 2024 and since then I have been going through with Monster transmission rather it took about **** to change out the first and now this. This has been a nightmare from h*** I sent over $5,000 with this transmission. I just want my truck running and to STOP the finacial bleeding.

  We understand you're frustrated, and we hear you. But wed like to clarify a few things.
  
  The issue you're referring to is not part of the transmission rebuild itselfit involves an external component (the driveshaft yoke) which falls outside the scope of our standard rebuild and warranty coverage. That said, despite this not being our responsibility, we still offered to go above and beyond our terms by purchasing the required adapter or a replacement yoke at no cost to you.
  
  Weve reached out multiple times to finalize that offer and help resolve the situationbut so far, we havent heard back.
  
  We genuinely want to help get your vehicle running, but we cant do that without your cooperation. Please respond to our outreach so we can finally bring this to a close and stop, as you put it, the financial bleeding.
  
  Sincerely,

  Monster Transmissions Warranty Team

  I purchased a 4l80 transmission from monster transmission. It was put into a 1951 ***** truck with a 6.0. The truck had zero miles on it. Its a new build. I now have 2800 miles on the transmission. It has started to slip I took it to the transmission shop. The pan was dropped and the oil is black with metal pieces. Monster will not warranty the transmission. They seem to have excuses to why they are not going to warranty it. My transmission shop said this is a common theme with monster transmission.

  Hi ******,
  
  Were sorry to hear about the issues youve experienced with your transmission. That said, we want to clarify an important part of the situation.
  
  Our warranty department attempted to start a warranty claim for you in November 2024. At that time, we reached out and requested that you complete the intake form needed to move forward. We never received a response.
  
  Without that completed form, we werent able to proceed with the claim not because we didnt want to help, but because we didnt have the information required to evaluate the issue properly.
  
  Were more than willing to help address your concerns now. If you're still experiencing problems, please reach back out and complete the warranty intake form. Were here to assist and want to work toward a resolution.
  
  Thank you,
  Monster Transmission **************** Team

  Business Response

  Date: 06/16/2025

  Good afternoon, Mr. ************************ you for your feedback. Were sorry to hear about your experience and appreciate the opportunity to clarify a few details.
  
  Your core refund of $500 was issued on 05/29/2025, in regard to the warranty claim, we did receive your submitted photos. However, as you have since filed a dispute, we are unable to move forward with any warranty support or communication until the dispute is fully resolved. We understand this may be frustrating, but once a formal dispute is initiated, we are required to follow the appropriate protocols to ensure all actions remain within those legal guidelines.
  
  We truly regret that this experience hasnt met your expectations. Please feel free to reach out directly if the dispute is resolved and youd like us to revisit the warranty concerns.

  Sincerely, 

  The Monster Transmission Team

  We are a custom auto body shop specializing in high-end vehicle builds. On November 1, 2024, we ordered a custom SS series transmission and NP208 transfer case rebuild from Monster Transmission. We relied on sales *************** advice on shaft length, but the initial transmission arrived with the wrong shaft size ( inch instead of 5.25 inches). The replacement had an even longer shaft (over 6 inches), and we were told to cut it ourselvesunacceptable for a professional job.Further issues included a front pump seal leak, stripped case port threads ignored despite requests for correction, and a transfer case returned with a missed hairline crack causing fluid leaks. Despite repeated contact attempts, Monster Transmission was unresponsive for weeks, then denied warranty coverage citing a 90-day limit, even though the vehicle remained in our facility and delays were caused by their poor communication.Though verbally promised a 3-year unlimited mileage warranty on a torque converter bought elsewhere, Monster Transmission later retracted this, claiming it only applies to full system purchases under certain conditions.Monster Transmissions response states their custom transmissions carry a 90-day warranty requiring installation within 90 days to maintain coverage. They offered a bench inspection at our expense (shipping and fees), credited toward repairs if approved.We find this offer unreasonable since their errors and poor service caused delays and defects. We refuse to pay any inspection or shipping costs and reject their warranty denial based on elapsed time caused by their delays.

  Business Response

  Date: 05/29/2025

  Thank you for reaching out and for detailing your concerns. We sincerely apologize for the inconvenience and frustration this experience has caused you and your team. As a company that strives to serve professional shops like yours with high-quality drivetrain solutions, we regret that your expectations were not met in this case.
  
  We have reviewed your account and communications thoroughly. While we understand your dissatisfaction regarding the shaft sizing, leaks, and the condition of the transfer case, we do want to clarify that the transmission purchased was a custom-built unit, which was explicitly covered under a 90-day limited warranty. This was communicated by our sales representative at the time of purchase and is also noted in the terms associated with the sale.
  
  We understand the nature of custom builds can sometimes result in unexpected complications, and we do appreciate your patience. However, per our warranty policy, coverage requires the transmission to be installed within 90 days of receipt. We understand that delays occurred, but we are unable to extend or alter the warranty terms retroactively.
  
  That said, we offered a bench inspection to assist in resolving this matter. The inspection fee, along with return shipping, is standard procedure and would be credited toward any approved repair costs. This policy helps us determine whether any failure or issue is related to materials or workmanship, which would then qualify for corrective action under warranty.
  
  We regret that this situation has led to dissatisfaction, and while we must stand by our original warranty terms, we remain committed to working with you to find the most cost-effective solution available. If you would like to proceed with the inspection, please let us know and we will coordinate the next steps.
  
  Thank you again for your feedback we take it seriously and will continue working to improve our service and processes.

  Sincerely,

  Complaint: 23392972
  
  I am rejecting this response because:

  We strongly disagree with Monster Transmissions response and find it both misleading and dismissive of the legitimate issues we raised. This situation has caused significant financial and reputational damage to our professional restoration business, and their refusal to accept responsibility is unacceptable.
  
  Our sales representative clearly stated that we were receiving a 3-year, unlimited mileage warranty, contingent on providing proof of torque converter purchase which we supplied. Being told now that the unit is only covered under a 90-day warranty is inaccurate and deceptive. This is not what we were promised at the time of purchase.
  
  Furthermore, we received incorrect technical guidance from their staff, resulting in multiple transmissions with improperly sized shafts. One technician even told us to cut the shaft down ourselves an unprofessional and risky suggestion. The transmission also leaked upon installation, and the case had stripped threads that we specifically asked to be addressed during the return. The rebuilt transfer case they returned to us leaked and had a hairline crack that should have never passed inspection.
  
  Their customer service has been extremely slow and unresponsive, with weeks-long delays in communication. By the time they offered a bench inspection, we had already wasted countless hours and dollars trying to correct their errors yet they expected us to pay all shipping and diagnostic costs just to have the unit looked at.
  
  To make matters worse, Monster Transmission curates its online reviews, only displaying 4- and 5-star ratings on its website. This is highly deceptive and gives potential customers a false impression of their quality and reliability. A simple online search will reveal many other complaints similar to ours. I hope future customers do not make the same mistake we did by trusting thier website reviews.
  
  We will never do business with this company again and we are currently seeking legal advice. We will not be going away, and we hope others do their research beyond the companys selectively published reviews. The practices weve experienced are dishonest, misleading, and reflect very poorly on Monster Transmission as a whole.

  I purchased a transmission for my truck on Febuary 24 2025. I received the transmission on March 6th 2025. When receiving the transmission, I was unboxing it and noticed that the torque-converted hold-down strap and not even tightened so the torque converter was able to move back and forth during transport. I inspected the seal and didn't see and marks in it so I installed the transmission in the truck. I followed the instructions and got the truck put back together. Upon starting the truck I noticed a severe leak from the oil pan and from the pump seal area on the transmission. I then had to pay to get the transmission removed, and upon removing the seal I noticed large gouges in the sealing surface where the pump seal sits. I sent these pictures to customer service and they noticed that there was also some other parts in the images that they said we not installed properly. Because of this, they were unhappy with the craftsmanship and work that was done. I then sent the transmission back on April 8th 2025. It is now May 28th 2025 and I have not gotten anywhere with customer service. I have been calling almost every week and rarely get anyone to pick up on their customer service line. Every time I call I am told they are waiting to hear back from there GM and unfortunately,y he just went into a meeting. I have been requesting a refund since the beginning of May and I keep getting the runaround.

  Dear Mr. ********************** and foremost, we want to sincerely apologize for the issues you experienced with your transmission purchase and for the frustration caused by the delays in our response. This is far from the standard of service we aim to provide, and we truly regret the inconvenience this has caused you.
  
  We have now completed our inspection of the returned transmission, including the images and documentation you provided. After a thorough review, we agree that the product did not meet the expected quality standards, and we fully acknowledge the concerns you raised.
  
  Were pleased to inform you that your refund has been approved and is now being submitted to our accounting department for disbursement. We understand this resolution has taken longer than it should have, and we are working internally to ensure that delays like this do not happen again in the future.
  
  We truly appreciate your patience and feedback it helps us improve. If there is anything further we can do to assist you or restore your trust in us, please dont hesitate to reach out directly.

  On 4/28 I ordered a transmission and the verification of my VIN by their team assured me that was correct for my 2016 ***** Silverado. Once the transmission was received, I arranged for mechanics to ***lace my faulty transmission with this product. The mechanics were confident based on the info I relayed to them that I was sent the correct transmission. Once the mechanics looked at the new one, (after they had fully removed my faulty transmission) they immediately saw that it was incorrect. The transmission never left the crate that it was shipped in. I am out an additional $1000 for my removal/installation of my faulty transmission. I have attempted to rectify this by requesting a simple refund and for the transmission to be picked up and restocked. The company actually does not even carry the correct transmission for my vehicle, an 8L. Unfortunately, I have had to find this out the hard way. In any case, I have been on hold over and over, only to be left with the option for voice mail. I have been told that the person who makes these decisions is sick, that the ***s are not permitted to make these decisions, or that it is out of their protocol. I have requested a phone number for someone to help me and have gotten nowhere. I asked ***eatedly to be ccd on any paperwork affiliated with my file to my email and have received no communications. Today I spent 40 minutes on hold, talked to the same sales *** twice who assured me he would forward me to someone who could help, only to he timed out again on hold. I have a brand new product that I just want to return and be refunded for. Again, I was reassured that this transmission was correct for my vehicle before the sale was finalized. This should be a simple return. I still have a broken vehicle that needs to be fixed and my money is tied up in this transmission. I made contact 4 times now and have yet to talk to anyone who can get me a solution or even begin the process of a return and shipping arrangements.

  I am rejecting this response because:

  As of 10 June 2025, I am still no further along with the refund of my transmission. I still do not have a phone contact for an actual representative to give me any up to date information on my return. I have emailed twice and gotten one response stating that they have received the transmission and my file has now been forwarded to the accounting department for review. The company received the transmission on 2 Jun 2025 at 1:59 pm. I did not get a response from the company when I emailed on 4 June. Again on 9 June 2025 i reached out and still have no contact information, only another department now is reviewing the return. When I call, I cant get anyone to answer. I call the sales department because they will always answer and they transfer me to a line that times out when Im on hold without the option for voicemail. I feel that it is the duty of the business to make this right and to have communication with the customer. There is no reason for this process to take this long and cause such grief and difficulty. The transmission was ordered on April 28th. We are now into June and I have yet to receive a refund.

  I am rejecting this response because: none of the shipping costs $598 have been refunded. This is extremely frustrating as zero communication was ever made with me. No one ever reached out, nor communicated with me except to say that I was refunded. I expect a full and complete refund. Again, it was confirmed by the company that this was the correct transmission for my vehicle by using VIN information, when in fact, the company does not even carry the transmission that I need. This is by no fault of mine. I confirmed by telephone and was assured this order was correct. I am owed the remaining $598.

  Original date of purchase was May 2024 for a transmission for a 2500 ***** Silverado HD, we paid for the transmission and did not receive until end of May. We then had transmissions changed out and sent the core back to the company. We had our vehicle back in June 2024 for only about a month and noticed that the temperature was going back up and there was leaking transmission fluid on the ground. We took vehicle back to garage and upon checking it the mechanic found the the seal was leaking along with a worn torque converter. We than contacted Monster Transmission about this and they did give us the approval to get the torque converter replaced and that a paid invoice sent into them for a reimbursement. This was done in February of 2025 and have not been reimbursed. When bringing vehicle home after this replacement, the temperature on truck was increasing along with slipping when the truck would try to shift into next gear. We then had a representative from Monster talk with the mechanic on all the issues and Monster transmission is supposed to send out a replacement transmission again as the one they sent was a faulty transmission, per the customer service **** I started a chat on 5/2/25 with monster transmission and was informed that a replacement would be sent out on 5/5/25. I have been trying to call, email, and do a chat with a customer service **** and now they are not responding to me at all.

  We would like to clarify that the information currently being shared does not fully reflect the accurate timeline or the efforts made by Monster Transmissions. The transmission in question was ordered by the customer on **May 16, 2024**, and shipped on **May 22, 2024**.
  
  The customer did not report any issues with the transmission until **November 7, 2024**, nearly six months after delivery. From that point, Monster Transmissions began working with the customer to address their concerns. However, there was a considerable delay and intermittent communication from the customer between November and **January 2025**, which impacted how quickly we could move forward with a resolution.
  
  In **February 2025**, the customer reported continuing issues, including transmission overheating. We advised at that time that the transmission needed to be removed and returned for warranty inspection and replacement. The unit was not returned until **April 7, 2025**, despite multiple attempts to coordinate this with the customer.
  
  Following receipt and confirmation of the warranty claim, a **replacement transmission was shipped and successfully received by the customer on May 5, 2025**.
  
  *********************** has remained committed to working with the customer throughout this process. We care deeply about our customers and regret that this experience did not meet expectations. It is always our goal to deliver high-quality products and provide timely, responsive support.
  
  We sincerely apologize for the inconvenience the customer has experienced and will continue to work toward ensuring full resolution and customer satisfaction.

  Horrible trans! Purchased a 5r110w trans and warranty February 18th, didn't see transmission until march 10th almost a month later. Had trans installed and trans failed within 3 weeks. no reverse function and a rough shift in forward motion, wouldn't shift past 3rd gear. Took it to shop to diagnose. Shop stated it needed a rebuild. Got into contact with monster transmission, sent me a direct clutch solenoid. They wanted me to do the install while it was sitting in a shop. Told them I want to have the shop do it. had to fight to get a "full reimbursement" Also told me over the phone given that it was so fresh, they would ship me a new trans to replace it if the solenoid didn't fix it. The shop installed the solenoid and it did nothing. Attempted to get into contact with monster trans for a week, repeated calls and voicemails left no answer. Been without my truck for almost a month now and couldn't risk getting ghosted, so went to bank and disputed payment. Only then received an email stating that if the solenoid didn't correct it, I would have to send the trans back. Nothing about reimbursement or them stating they would expedite a new trans like they said before. I have no interest in being involved with this company any longer. Just want my money back for a faulty trans and crappy warranty.

  Dear Mr. ********************* you for sharing your concerns. We sincerely apologize for the inconvenience you've experienced. We understand how frustrating this situation has been for you.
  
  However, we have not yet been provided with an opportunity to inspect, repair, or replace the transmission. Once the transmission is returned to us, we are willing to evaluate it and discuss possible repairs or replacements, as well as any applicable labor reimbursement once your vehicle is operational again.
  
  Additionally, since a chargeback has been filed, we are currently unable to proceed further until that matter is settled. We genuinely want to resolve this situation in a satisfactory manner and encourage you to contact us directly so we can work towards a solution.
  
  We appreciate your understanding and hope to have the opportunity to address your concerns properly.
