I am old school guy so forgive for asking a question that might be a lil dumb....
I just bought a S4 turbo II motor and tran. I know that motor is a turbo II by the stamping on the housing. But how do I know if it a turbo II Tranny? Is there a number or anything that would say it a turbo II.

 

one way to tell,and this Is assuming that you already have a N/A..The driveshaft of an N/A will NOT fit into the tailstock of a TII trans.(splines are different.)

 

the TII trans is more "rigid" looking lol
it has ribs going vertically along the trans, I think there are 4-5 ribs on the trans if I remember. It just looks more stout compared to the n/a trans.

 

The Turbo II tranny has a large inspection plate bolted to the bottom side. The n/a tranny doesn't have this.

 

also, if you want to know if it's S4 or S5 T2 tranny, there's a different # of bolts ( I think) that hold the bell housing on to the gear box

 

I try to post some pic of it today or tomorrow. Thanks for all ur help.

 

here is what the turbo trans looks like:

 

actually, the non turbo transmission doesn't have any bellhousing bolts as the bellhousing is moulded to the case. the turbo transmission has a removable bellhousing.

anyways the picture above shows the differences between the TII transmission and this is what the non turbo transmission should look like(not my pic):

 

This is a turbo transmission:





This is a non-turbo transmission:






Also, the TII transmission has an inspection plate on the bottom.

 

Thanks guys. After looking at ur pic it a turboII!!!!! Am happy!! I got a really good deal for the short block and tranny. Hopefully it in my RX2 in the spring time. Thanks for all ur help.
