My 4L80e in the Hummer just started acting up....
No codes. Works fine cold. When warm looses OD, then third. Then starts slipping in first and second...
Fluid is fresh one year ago. 100 000 miles.
Dipstick is showing fluid. Strangely there is loads of rust at the top of the dipstick....thats new since I last checked it but its been a really wet damp winter.
Just got home and first code poped
P0236.
I had it last week and changed the MAP sensor today. Guess I was wrong for 84 dollars...lol
Ill search the threads in a couple hours for a similar issue.
