6L90 with TCE2800. Struggling to get smooth lock

Hi all, first time poster & first time using HPT. Being doing a bit of reading but I'm still not making any head way on getting the TCC to transition from unlock to lock smoothly in 6th gear.

I've been changing TCC apply pressure ramp, TCC reg offset and TCC reg gain but getting no improvement.

Could someone please have a look and see if something obvious sticks out???

Log and tune attached. The problem I am having is shown in the log file, the TCC pressure ramps, then drops off then ramps. It repeats this cycle multiple times until finally complete lock is achieved.

I am road testing on the same piece of road and trying to maintain a steady 25 - 26% throttle each test. I am up to revision 9 but all my logs look similar to the one posted.

I think I'm in the right area. I made significant changes to the TCC pressure ramp apply table inspired by some of the tunes in the repository.
