Auto transmission issue
 

Scanned my car and got code p2757. Cleared the code and car shifted fine. Went to my tuner for revisions to my tune and suddenly my car started shifting like this. Car is boosted with greddy t620z turbo kit. [URL="http://https://youtube.com/shorts/qbeDAAs3Q-g?si=J_eNYYWOgGak-RN_"]

Your link doesn't work.

But do try changing the transmission fluid. And while you're there, change the diff fluid if you haven't recently.

I changed both fluids last december.

Sounds like the extra torque may be putting more strain on the transmission than it was intended to, which might cause mechanical problems. Also, the problem could be your torque converter clutch pressure control solenoid as heard in the video, it sounds like a little bit of gear slippage. Even with the codes cleared the issues may not be resolved.

Thank you for the input i’ll try to source the solenoid.
