2002 5.3L with 4l60e swapped - shifting issues
I am new to playing/tunning automatics (my first LS swap is my 5.3L with nv4500) and am helping a local mechanic with light tuning on LS swaps
base tune with a lt1swap flash and mod
symptoms: when up to temp, 3-4 stops shifting. After cooling down, and restart, then 1-2 doesn't shift.
No DTCs, 4l60e was rebuilt 5k ago.
Now for logs, which channels are needed? Just normal tuning ones, or are there transmission specific ones?
appreciate any thoughts

thoughts on how to learn more of auto tuning?
