DCT Upshift Delay

On my last three ~ 25 min sessions today at COTA started to have delayed up shifts in the last 1/3 to 1/2 of each session. No lights or errors thrown - just lagging shifts. Started having to shift 500 to 700 rpm sooner to avoid the rev limiter. Shifts were also noticeably more harsh. Does this sound like dct overheating? Temps were around 90.

When I had similar behavior, it was DCT pan and Slonik pan has resolved it. Run codes to confirm whether it is overheating or loss of DCT fluid pressure. My code read as pressure loss, not overheating

No more lagging or clunkiness now!

Should it throw a code if either of the two are happening? I never got a cel or anything like that.

Please forgive my ignorance here - could a loss of pressure occur on straightaways? On the long back straight at COTA - coming out of 11 in 2nd and then have it happen all down the straight wide open through 5th. Not sure why but I have it in my head that pressure loss would have some lateral g’s involved?

Thanks!

I've had it get clunky and laggy, but no limp mode. Never checked codes for that, assumed it was just heat. When I finally had it stay clunky very long in a session and drove on a very windy course, I finally got limp mode. Pulled off track and ran codes. Got loss of pressure code.
