Differences between a non turbo S4 tranny and S5 tranny?
 

I was wondering what are all the differences between an S4 ('86-'88) non turbo transmission and an S5 ('89-'91) non turbo transmission? I know the throws are shorter, but there has to be more than that.

My next question is will a non turbo S5 tranny bolt right up in a non turbo S4 car?

Thanks,
Isaac
