7AT Issue Help Guys!

It looks like it's shifting normal to me. These cars shift all the time, try shifting with the paddles and see if you feel anything.

I watched mine & yours does drop a little more then mine but it sounded like you were accelerating slowly. Does it do it if you accelerate harder?

Looks and sounds normal to me from the video.

The 7AT is already superior to the 6Spd Manual. Just get an UpRev tune or Ecutek tune and it will leave the 6Spd in the dust.

Thanks for the input guys. It does it in M-mode and under harder acceleration. It has never done this before (Or maybe I have never noticed it) By the way it doesnt happen when shifting gears, it happens in the middle of 3rd.

Could you guys tell me some signs of the tranny slipping to see if they match whats happening?

It does not appear to be slipping.

JWillis72 · 02-10-2016, 05:33 PM

Does it rev higher without accelerating? It doesn't look like it.

No, it doesnt. Its just that drop in rpms in the middle of 3rd gear. I can actually feel the car jolt a little.

Your sure it's not just going to 4th?

Sometimes you can't feel the shifts in this car.

You mentioned after a cold start you notice it. Does it always do that or just when its cold?

Okay so my car actually does this too, no idea what really causes it. My mechanic also says it is fine and it doesn't seem to be causing any harm. I just attributed it to a quirk in my gtm upgraded transmission or tune.

It happens most of the time in third gear, but if I switch to 4th gear before it happens in third, 4th will engage at a lower than expected rpm cause it drops during the switch. If that makes any sense, lol. Maybe I can grab a video of mine too.

I really only drive my 7at in M-mode so I've gotten familiar with this little problem. It only happens under light acceleration/city driving before my oil/trans is up to temp. When I'm really going for it the shifts are perfect.
