I might need to replace my original TCM
infiniti doesn’t sell the TCM with the valve body cost 1550 without programming....
if I get a used tcm how to I match it properly
which numbers do I match?
Which numbers have to match in order for the swap to work?

 

I'm going to guess you have a 07-08' G35. Just make sure you get one from a 07-08, they are different than the previous gen G35 cars because the redline was raised. While it's out you can throw in a shift kit if you want way better shifts!
