A T5, 5 speed is a pretty good stick shift, as long as you don't put a blower on the 258..My experience with the "other" 5 speed that came in, say, 1990 Commanche with the 4.0 engine is not
positive... And they came with a hydraulic clutch cylinder that
is integral with the T/O bearing...(they leak after a year or so). A Chrysler torqueflite 6 came with the 232 in AMC cars.
A great trans but no O/D. Probaby a Jeep 4.0 with automatic,
out of a mid 1990's Cherokee would do the job.. They can be
converted to carburetion and stand alone electronic ignition,
fairly cheap. I am a AMC fan.. But, to me, a GM engine just
looks the best in a GM product...How about the small Buick
straight eight for different... Man, they are REALLY cool.
