Does it try to lock up at all? It could be a spun stator shaft(GM has a bulletin about this), bad F solenoid(lockup solenoid), or a burnt converter.
 
Yes it locks and I can feel it come in and out under throttle.

The truck feels normal (for it). The tranny is definitely tired and when towing I get 8 codes total by the time I get to my destination.

I have started driving it harder lately and the tranny hasn't limped since then but it's definitely well worn.

Might want to save your $ and see about contacting MikeL for an Inglewood unit.

A new Tranny was on the to-do list. Its getting a full repaint and body work in july (hail damage check), a tranny was next on the list.

I was hoping that since it doesnt limp that there was a bad solenoid or sensor causing the codes. I guess it just means its smoked and slipps alot.

Definately going to need a heavier duty unit. I cant say I am unhappy with 215K on the tranny and alot of hard towing.
 
Changed tranny fluid (double flush amsoil torque drive) and temps are down and no more code.

Now (unrelated problem) I get v0100 lost ecm connection code. Any ideas?
