I recently purchased an 07 aveo5 with 100k miles on it. The transmission was serviced at 80k miles according to the reciept and service sticker. 2 months after I purchased it the speedomtere stoped working and the car only runs in 3rd gear. I took it to a transmission shop and the thought it was computer related and advised I take it to a dealer. I hauled it to the dealer and they claimed it was the TCM. They claim I couldnt use used parts and replaced it with a new one to the tune of $880. Well, that didnt fix it so now they claim the transmission is bad too and want to charge me $4600 for a certified tranny. No thank you! Anyway, I want replace thisone myself to save on cost and the local parts place has a low mile 06 or 08. Will either of these work wi th my 07?
