06 TBSS 6.0
Swapped a 4l80e in, did the pin swap u to s, discarded s, relay for 2-3, and tcc pwm relay, stays in third, even after stopping.
getting codes p0787 and p0961
Appreciate anytime spent

No tune attached...post it up and Ill take a look.
It's more than just a single pin swap, IIRC it's 3 pins that need to be swapped/removed.
what did i miss from above?, forgot to mention i have an adapter harness on the trans end too

Ok, how exactly is your setup connected then? If you're using a harness, not sure you need to do ANY pin swaps...
-pin 45 moved to pin 26 on the tcm
-on the trans adapter harness pin U goes to S on the trans
-ISS is pinned to the tcm pin 26 and 3
Need to move T (60E TCC on/off) to S (80E TCC PWM).
Discard S (on 60E/harness), not used on 80E (looks like you did this).
Relay mod to invert the 2-3 signal (looks like you did this).
In your first post you said you used the 60E TCC PWM signal with a relay to make it an on/off as the 80E TCC is an on/off setup. Is this correct? Might be worth it to try using the T -> S pin swap if you can.
That file doesnt open for me, says it failed the validation check. Running the latest 2.24.241.
You're going to have issues unless you change the programmed gear ratios... Unless you disable the ISS.
