Had automatic transmission rebuilt on my Pontiac Montana after just 53K mi. Saw part (gear +planetaries) and they were ground right down, virtually flat. Well maintained, must have been faulty part, they said.A few days later, the car experienced same problems--wouldn‘t go into gear at a stop sign. Transmission shop says it‘s likely a problem with the antilock brake system that is causing damage to the transmission, although I noticed no problem with the brakes. Dealer where I bought my lemon says this is impossible--ABS problems won‘t cause transmission damage--and it must be a transmission problem that didn‘t get repaired properly.Transmission shop said they‘ve changed all the applicable parts.Who can I believe?? It takes 2 mechanics 8 hours to open the transmission and check it, so I can see why the shop isn‘t eager to admit a mistake.I just want to be able to drive this car far enough to reach a dealership to trade it in!!! Thanks.
I would say take it to a real shop, for some reason people on here(some) have no clue that the brakes are connected to the vehicle!! I dont care if they don't like my answer brake drag can cause trans problems but as Auto man said it seems to not be the case in your situation! But beleive this I have been a mechanic for 16 years and I HAVE SEEN THIS HAPPEN so Good Luck and take it to a Experienced Mechanic
Brakes are not connected to the transmission--so forget that talk--the shop sounds either stupid or they are a rip off . Get a new trans--stop fooling around any further---new is new--that is your best choice---you spend the same for a couple of parts then the labor--and you still have an old trans--a new one has at least a 3 year warranty--front to back. A few parts will not mean a thing. That shop that did just parts was a rip off and took you to the laundry--you should have gotten a new trans all at once--in one day you have 3 years of extra life in your van. Don't trade it in--you can just buy another used junker and keep spending money again. keep the van--get a new trans at a DIFFERENT shop---go to a reputable transmission repair facility--look under trans in the phone book.
No way would a problem with the brakes affect the transmission. If you had faulty brakes you would know about it, if the ABS was not working the brakes would default to normal non ABS operation, and a warning light would come on. The ABS only comes on in very hard braking on pavement or braking on a slippery surface, so 99.99999+% of the time it does nothing. Lots of people can own an ABS equipped vehicle without ever using the system. EDIT: if you had dragging brakes you would fry the brakes long before you had any transmission problems.
