I am about 99% sure the answer to that is 'yes'. The only concern I know of is that they changed the spline count, I think that was around 1997, but that would apply regardless if it was a 3 or a 4 speed
I have a question and I think you will know the answer. Will the transfer case from a sidekick 3 speed automatic transmission interchange with the sidekick 4 speed automatic transmission.
