2004 350z stock/ automatic.

Just recently, I noticed when I depress the throttle fully, the car doesn't kick down and I get almost no acceleration or slow acceleration. The car kind of surges but goes nowhere. My engine rpms go up to 5000, but I'm hardly moving. The kicker is, the car runs fine on normal driving (street and mostly freeway) just seems to have a problem with full throttle kickdown.

It's weird, it appears maybe the tranny is acting up? But the car drives fine normally. Any help would be appreciated, Thanks in advance.

Welcome to NICO Club!

Just a basic question here... have you checked your fluid levels and quality? If not, do it. That's your starting point. If so, tell us what you saw. Thanks!

Thanks for the reply . the fluids are OK oil OK .

Maybe a dirty / clogged fuel filter?

Not getting a check engine light?

Have you had any repairs or parts replaced anytime? I wonder if maybe the throttle pedal relearn was ignored at some point. Ever try that?
