Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
what model Chevy is this ?
I am a GM tech, so I'll offer you some advice.
We have the same car in Australia.
With suddenly no drive in forward or reverse, it could be one of a few things, but hopefully not too costly.
Does it have any red fluid leak?, it could happen at any time.
This is a very important check to make for me.
It could be a TCM, valvebody, or another electronic fault.
The valvebody is a plate assembly inside the transmission with all the shift solenoids.
The TCM is the Transmission Control Module, has the program for shift points
Can be updated as necessary, logs codes for faults, can be viewed for data etc.
In your case the TCM and the valvebody are one unit called a TEHCM.
(Transmission Electronic Hydraulic Control Module).
That is some good news.
Hopefully it is an electronic issue, and a code has stored.
Will give the techs a path to take.
Have you taken the car to a GM dealer?
Unfortunately that does happen with the GM GF6 transmission.
I have seen this many times, in and out of warranty.
I didn't want to scare you initially.
The GM dealer is most probably correct.
A new or SRTA transmission is the best option for you.
Hi again Nicolas,
I have seen a few cars, Cruze and Captiva, have no drive.
I have experienced one on a lengthy roadtest with another tech on board and a laptop viewing transmission data.
I had a box of neutrals, no drive after 20 mins. Shut down, cool down a bit, drive back to workshop. Vehicle got new trans under warranty.
The new transmissions are better now, I have not seen a duplicate failure on any car.
I hope this helps you.
I have repaired a lot of transmissions, although these days they are so complex, it is more productive and more cost effective to replace it as an exchange unit.
Your price sounds about right to me, around $9000 AUD fitted.
I'm sorry to bear bad news to you.
Does it still not drive even after cooling down?
If it could drive, would you contemplate trading the car rather than spending that money on it?
Could be cheaper, BUT will it be as good?
It might be difficult to locate one as well.
Try your local auto transmission shop.
