i need to know what transmission is compatible with my 2005 g35 AT sedan?

 

Welcome to the G35 Driver forums Jibreel! What's wrong with the AT that came with your sedan? If it's broken have it rebuilt by a quality trans shop, often they're better than buying a new one! Compatible, are you asking the right question?

oh, when i mean compatible i mean is there another year AT i can use, like can i put an '06 AT in?

 

I think when I looked into this last you could use the '03-'06 but you need to verify the electrical connections, there was a different harness connector somewhere during that era but you can actually change the harness if needed. Call your local wrecking yard and ask them about the interchange for that year, they deal with it every day.
