Complaint: BBB My 1998 GMC van had a slipping transmission and the transmission code light was lit. I took it to VANVO TRANSMISSION, the owner took it for a test drive, said the transmission needs an overhaul and it will cost $1350.00. I told him to fix it and I got it back and paid cash on 11/4/13, one year warranty. Before he did the work he said he would warranty it for 18 months. The van started slipping again, the same light, with the same code, about the first week of January, 2014. I returned it to the owner, VANVO TRANSMISSION, he said; I can fix it by replacing more parts and it will cost $45.00. I was concerned as I just paid for an overhaul for the same problem so he agreed to refund my $45 if it still had the same problem after he replaced those parts. I wrote this out on the invoice: "If replacing the parts don't cure the problem (P1870)-code from being triggered, refund $45 if parts don't fix/repair the problem". He assured me the parts were a 99.9% cure for this problem and it won't cost me anymore money after this. On or about 1 month later the same slipping and the same light with the same code happened again. I returned it again and he replaced another part on 2/5/14. He reset the light and told me this is a for sure fix for this problem and I won't have any more troubles. On or about 2/14/14 the van started slipping again, the same light, with the same code happened again. I took it back and the owner, VANVO TRANSMISSION, told me he is positive that if I pay him for yet another part that he is now 99.9% sure will cure the problem once and for all. He said this part may be as much as $1000.00. I took it to another shop, who I've been taking it to, throughout this ordeal, who has been providing me with a second opinion. ** *** *** ** **** ****** owner, ******, wrote me a description of what I should do and what he would have to do if I brought it to him. This is what he wrote: "Customer states that check engine light is on all the time", "Scan found code Po1870 Transmission component slipping/Internal transmission problem, transmission needs to be removed from vehicle for inspection". "Customer will take back to where transmission was recently overhauled". "Estimate cost of repairs to Rebuild transmission $2,000-$2500". I returned to VANVO TRANSMISSION and asked the owner to either fix the problem or refund my money, I read the letter ****** wrote me. He refused to stand by his work or refund my money.
Desired Settlement: refund my money or pay another shop to repair it right.
Mr. ******** brought the van to me on 11/04/13 before he bought it and wanted an estimate on transmission repair. Estimate was $1350. to rebuild transmission. Transmission was rebuild and he returned on 1/09/14 with the check engine light on. I ran a free diagnosis on the check engine light and it showed code PO1870. I told him I would replace 2 TCC PWM solenoids and if the code comes back I will refund $ 45.00 for the 2 solenoids. He was also told at that time that if the solenoids does not cure the problem that it is PCM Computer. I made an appointment for him to return on March 3 2014 at 9:30 am to check transmission and motor mounts. Also the PCM computer serial number to get an estimate on PCM computer cost. Mr. ******** never showed up for the appointment.
(The consumer indicated he/she DID NOT accept the response from the business.)
I rebuilt ********* 1998 GMC transmission only and I warranty for all the parts inside the transmission only and the torque converter; I'm not responsible nor warranty for any electrical, PCM or wiring issue.
