1994 STS 4t80-E transmission stuck in 2nd gear


Recommended Posts

Can this be replaced with the transaxle in the car?

I have the trans pan dropped, and can see what is broken on he original solenoid, but I can't find the

clip to release the solenoid body from the transmission. Is it internal?

That is a cracked shift solenoid and its the reason your tranny is defaulting to second gear. You need to remove the lower valve body, but be careful there are check balls the MUST be put back in the same location. Also, MAKE SURE you use the new bracket that comes with the new solenoid. Replace both of them, there is a shift solenoid kit at the dealer, and change the filters and pan SEAL, dont use a CORK gasket, use the proper seal.

Do a search here under shift solenoids there should be a lot of info for you to access, Mike
