2.8L to 3.1L Transmission Swap


Dark Ride

Recommended Posts

Sorry for asking a question thats probably all over this forum, but I've got a friend who needs a transmission for his 3.1L and I've got a 2.8L trans sitting around with a bad engine. Do they have the same transmissions? I thought they did but I wanna be certain before I start pulling things apart.

 

Thanks,

Mitch

What year of 3.1?? I believe that 93+ got the 4T60-E. If thats the case, than no, your transmission won't work. Other wise, there really is no reason that it shouldn't work.

Provided they are both 88-92 or whatever with the 4T60 (non-e), you might need to swap the VSS (vehicle speed sensors) from the tranny.. otherwise the speedo will be off. Not a big deal.
