Depends on the model
No.
Not usually.
The 455 will fit. The transmission might have a shorter tailshaft, though.
A transmission from a 1993 Toyota pickup will fit into a 1994 Toyota pickup. The Toyota transmission will not fit in to other makes and models of pickups.
No. My daughter has the same vehicle and for some reason, GM changed the models in 1993 to be unique to that car. The 1994 is different and the computer will not work, as well as some sensors, mounts, etc.
Check the diameter and circumference of the flywheel for each transmission. IF they match, then the flywheel will fit.
Yes
3.1L
No
Yes It would if its 2.3L engine size. Also, fits Oldsmobile Achieva of same year. Thanks
Log on to an auto parts site. Get replacement transmission part numbers for both year models and see for yourself.
As long as it has a Buick/Olds/Pontiac bolt pattern on it, it will fit!
