4L80e Not shifting to 3rd at WOT I recently swapped a 4L80 into my 2011 Camaro, I have everything working fine except for the 2-3 shift at WOT. It shifts 1-2 and 2-3 just fine at light or part throttle, and 1-2 shifts fine at WOT, but I have to let off throttle before it shifts to 3rd. it does this in auto or if I try to manually shift. I am running the PCS standalone controller, and not sure if this is a tuning issue or needs to be rebuilt.any suggestions?

Yes, I removed the pan and replaced the filter while it was out and noticed it had the kit already installed. One thing I did notice, the previous owner had the wrong fitting in the rear fitting (it did not have the long tube on it). I installed the correct fittings before install. Could that fitting be the root cause of this problem?

I just drove it again, it shifts fine at light throttle, it seems that more than 50% throttle it does not shift until I let off the pedal. I am going to lower the shift rpms and mph and see if that help.

How could u tell the hd2 kit was installed? I've been wondering if my 4l60e has one but don't know what to look for. I'm doing a verter swap so was trying to figure that out while I've got the pan off changing the fluid n filter.

When I had the pan off I saw the little plate with the transgo logo that's a part of the kit.
