What are some ways to tell if you have a JDM ITR Tranny w/ 4.785 final drive? Can someone help me out. Can you name me as many ways you can think of.

thanks

 

count teeth on the FD and countershaft

 

Doh that sucks... there has got to be some markings on the FD to tell right?

 

or compare rolling speeds rpms.... i don't believe there are any markings, someone correct me if i'm wrong.

 

Rolling speed will work.. at 80 my ATS is off by 500 rpm compaired to stock.

 

99% sure I have seen pics of trannies with "4.785" stamped on them....

 

Well, you can check the serial number on the tranny casing. Dee has information on how to identify the tranny, whether it's 98+.

Whether or not someone replaced the 4.785 fd w/ the 4.400 counterpart is another story.
