are the 92 SSE and 95 SSE Transmissions compatible?

I'm Looking at a 92 SSE that I used to own and has now blown it'* trans.
I'm also looking at a 95 SSE that supposedly has a bad head or gasket.

I will hopefully end up with both cars to make 1 good one.

Your looking at different wiring on the trans. Are they both 4T60-E'*?

You're looking at a mess of wiring and a component. The 92/93 don't report trans temp. They have a thermal switch that opens or closes at specific temperatures to put the car into limp mode.

The 94/95 4T60 has a thermistor that reports back to the PCM what the actual temperature is. There are numerous topics here on this subject. Do a search on 'trans* wiring' in the 92-99 section.

I would guess that the power output of the '92 is considerably less than that of the '95. They are different engines, right? And that the Powertrain Control Module will be expecting a different trans than the one you are installing. As I understand it, there are parts in the trans like accumulators, springs and valving that are adjusted for the torque output curve of the engine it is mated to. Same thing to a lesser extent with the torque converter. So, even if you did get the wiring to match up by swapping some wires (if that is practicable) you may still end up with a trans that does not shift in an acceptable manner.

Then there is the matter of the final drive ratio. I am guessing you would want those to be the same. Are the RPO codes for the trans the same on both cars? F17 for the 2.84 ratio or FW2 for the 3.06?

I have not tried to swap different years and models - maybe it would work, but if there was little difficulty doing it, I would expect that salvage yards would say the different year swaps were OK. But, for the '92 na and '95 na, they don't. Take a look at compatibility on: http://www.car-part.com to see.

This may give him some idea....



Let me know if this is not what you need. I have another page to reference for the electrical I do believe.

oh well, I guess I won't swap the tranny.
I'll just see which one(*) I get
