take them out and lay them side by side. It could be as simple as swapping sensors.

doubtful as the actual transmissions are different, a341e vs. a340e, as well as a gearing differential.

oh, plus wiring the trans into an OBDII '96 will be hell if you dont have the right sensors/harnesses/etc.... on that old trans.

Well..

He can make it work, if he wants to. The most fundamental aspects of the transmissions are the same: bellhousing and case. If he has to swap over the extension housing to make some 95-97 specific sensor fit, so be it. I've seen people mate 4wd A340F transmissions meant for the 3VZ motor to the 1UZ-FE and make it all work with the 1UZ computer. And his most difficult issues wouldn't apply in the thread starter's case.

I for one am keenly interested in the differences between the transmissions. As far as I know, there are two sensor differences, and perhaps a solenoid or valve body difference.
