What is the differance between S4 and S5 turbo transmissions? I've herd the 5th gear is differant but how much? how many mph differant? also what has to be done to install a S5 turbo transmission on a S4 turbo car?

 

Anyone?

 

I'm told, through Hypotntz7, there Isn't any difference, except more "ribs" to the casing.

 

I always though 1st gear was taller in the s4s....

 

Again, this was mentioned In a PM.

 

mounting is differant

 

exactly, the actual crossmembers are different shapes..but they'll bolt to the car if you have the corresponding mount

 

Guess that would explain why the crossmember I just bought wouldnt fit, the dealer thought they were both the same.

 

I believe that the S4 had a 5th ratio of .762 and the S5 had one of .719.I think it is roughly a 10mph difference at any given rpm.

 

How much for the crossmember? I'm putting a TII trans in my 7 right now...TII swap. Thanks.

i got a s4 tranny in my s5. it would bolt right in..also the throw out bearings are differant.
