Question for Boosted AT users - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Soloside · 12-04-2017, 09:58 AM

Forgot how to search up users and message lunatic since I've always seen his name brought up in discussions about automatics, but I didn't know how and figured I'd just ask the general public.

My car is running into the issues of getting a p2757 CEL code popped during 4th gear pulls. Was wondering if anyone had experience with it and how they managed to keep the code from popping up? Error says something about a Torque converter clutch pressure control solenoid.

I have never seen that code myself.

Does it shift any differently when the code pops up?

Car's downshifts become very sluggish. (instead of the RPM snapping up, it goes up slowly in a linear fashion) Shifting up doesn't have any issues.

Does the code pop up after you upshift from 4th? I know on boosted AT cars the shift from 4th-5th can be a little rough on the transmission when at full throttle because the revs don't fall quick enough before engaging 5th causing a jerk.

Have you tried having the dealer reflash your transmission ecu?

The CEL pops sometimes when I'm full throttle going 3rd into 4th. Happens a lot frequently when I'm pulling 4th gear from a lower rpm like 3k.

Not sure if the dealer is even willing to take my car in to look at it. The last one I took it to refused to even diagnose the CEL because my car wasn't stock anymore.

I'm running the Edelbrock SC on my 2017 86 here in Hawaii, USA.

No codes have popped up and I had my boost for almost 9 months so far.

I have done drags and spirited droves dozens up to 125mph range without any issues.

Although I think for my case a lot of the issues that wouldve came up was prevented thanks to the quality tune that I got from Delicious Tuning.
