I have an 03 G35c and I am thinking about purchasing a 03 350z 5AT.

I am wondering if there are any differences between automatic trans specifically between a 2003 trans and a 2004 trans? Anything I should know before I purchase a different year trans?


thanks

 

yeah, the tcm moved into the transmission in 04.5 i believe, in 03-04 it's in the passenger side foot well.

 

Thanks!

anyone else have info?

 

That's all I know about the difference as well. My car is a 2004.5 G35 coupe and the TCM is integrated into the valve body, like every subsequent model year. I do believe that if you have an 03 AT going into your 03 car, you should be fine. I have a 2006 torque converter (reworked) in my 2004.5. I am not confident that later year 5AT components other than the TC will work in my car due to differences in the TCM programming, CAN signaling etc.

 

Thanks for your help
