AT Check light (changed the trans. But the problem didn't got fix)
 

nissan 350z 2005 is being giving me the at check light and sometimes it doesn't shift properly and just cramps up the RPM and then makes a really awfull shift I have a video


that was with the old trans but with the one I just bought is still doing it the same thing it only has 43,000 miles, the old one had 240,000 miles that why i though it was just the trans but apparently is not
I really need some help with this problem I took it to the dealership and they were the ones that told me to change the trans but it didn't help, I also changed the speed sensor before the trans but it didn't help the problem at all
I scanned the car and is also not giving any codes

Only other thing it could be is the computer. Unless they didn't actually replace the transmission.

What do you mean by the computer?

Easy answer is just take it back to them. They diagnosed and did the work on it.
