I just got an 08 aveo with a tranny issue. It'll drive fine when cold shifts like a new one should. Then gets warmed up and loses all gears no check engine light or anything stored in it. My normal thought would be shift solenoid etc. But I looked at gmpartsdirect.com and they dont have one listed
Anybody here have any ideas
Have you checked the transmission fluid level and quality?
New and full. After it happened they changed the fluid
There are two valve body solenoids. PN 93741833
Are these what you were looking for?
You need to get an OBD reader capable of reading the TCM data stream. Torque Pro for Android is the most popular but there are others as well. Once you have that, watch what TCM is showing when it goes from cold to warm and loses functionality.
Ok I'll try that.
What code(s) did you get? It could be the torque converter clutch.
I would suggest to pay for a transmission rebuild. The fact that yours is 11 years old is enough to know it's time - I have had multiple aveo's (3) and all of them experienced tranny probs - mind you - i drive them to 200k miles +
- one time i paid for a tranny replace (used tranny) not worth it seals eventually leaked - once i paid to put new seals in - within 20k they started leaking - again a complete rebuild by a foreign car tranny rebuilder - would have been cheapest route -with a warranty $1700
