Customer Question

I have a 2005 g35 rwd sedan, I recently replaced the tranny with a certified used one everything was done exactly how service manual said, but when I fired it up it only moves from idle fwrd and rev no throttle accept when I reset ecu then I get about 3,000 rpm's when floored, then let off acc pedal and nothing, had everything scanned the dealer even and they can't figure it out now they say it's a bad ecu? Does this sound right and have you heard of any other problems similar? Also threw codes for manual mode up/dwn?

Hello and welcome to JustAnswer!

If the trans is slipping then it's going to be an internal issue. It sounds as if you're describing the trans slipping when you try to accelerate.

Can you describe exactly what is happening?

What was the original problem?
Has the fluid level been rechecked?

What P codes are setting?

This is for the manual mode switch in the shifter and isn't related to symptoms other than not being able to up and down shift manually.

No engine relate codes set and the engine light doesn't come on?
