Transmission compatibility


AL

Recommended Posts

My cousin just called me and told me her tranny died in her 94 Buick Century 3100... I was thinking the tranny was different in 94 then in 96 (I have a 96 3100 GP tranny)... Are they different or would the one that I have work in her car?

 

If they are different, I have another request, Does anyone have a tranny that would work in her car? And the closer to Fort Wayne, IN you are, the better...

An A-body like that will have completely different FDR and possible other minute differences.

 

My guess is A-bodies went OBD II at the same time W's did, but I could be wrong.

oops. i saw century and thought regal...

 

yes, OBD2 in 96, though the 94-95 A cars had removeable PROMs and are tuneable the way other OBD1 cars are.

 

a 94 A car has 2.97 gears, a 29 tooth VSS reluctor and a 1630RPM stall.

 

WAY different.

1994 and 1995 are standalone transmissions remember the obd 1.5 guys?

 

 

 

That sucks, although when it comes to automatics I wouldn't fuck with different years if I was replacing.

HUH? what's the ECM got to do with it?

it doesn't. he is incorrect.

 

 

but the 94 a-body trans is not compatible with a w-body trans.

that's what i was thinking... there weren't any internal changes that i know of that happened between 94 and 96. the PCM doesn't control it any differently either.

The back of the trans from the the A bodies and the Grand Am transaxles dont work in the W-body because the mounting system is different and the bolt holes are in the wrong place for the mounts. I am not incorrect Ken, when you do a parts search for compatible transmissions using a 1994 or 1995 Cutlass on car-part.com ONLY 1994 and 1995 transaxles come up. The PCM/ECM are coupled together on these cars. The 4t60e is semi electronically controlled Thats what it has to do with it.

there is lies the first problem. car-part fails to clarify that although different, they can be swapped. NOTHING to do with the PCM at all, but rather a change in the RING GEAR and DIFFERENTIAL.

 

hmm... I have to refind the diff info.... but here is SOME info...
