I have a 2003 G35 sedan with the 5 speed transmission and was thinking of putting a six speed auto from a 350Z. What is needed to do this and are there any advantages or disadvantages to doing this. Thanks

 

Hey Axespino. I recently bought a 2004 infiniti g35 coupe, and the main issues that I have had, is finding a Manual ECU that WORKS, and then also, the plugs for the reverse, and park light switches are different if you swap to a manual trans, so you have to dig through FSM to wire your own stuff. Hope this helps with a few things, but honestly those are my main issues.
