'03 V8 w/210K
No issues prior. From a stop when accelerating it is very sluggish as if it's starting out in 3rd gear. Operates normal above 15mph.
First code P0751 popped up (transmission shift solenoid "A" performance or stuck off )
Scanned again later and P0974 also showed (transmission shift solenoid "A" control circuit high)
I did some research but I couldn't find anything specific to this platform aside from debris can get lodged in the solenoid causing it to stick open or closed.
I went ahead and purchased the dealer part dropped the pan and swapped it out. Got everything put back together filled the fluid, cleared the codes test drove and P0974 came back. Same problem from a stop when accelerating.
I didn't check voltage on the harness connector when I had it apart but it visually looked solid.
Does the PCM need a reset of some kind after replacing the solenoid? Wondering if anyone has had a similar issue with solenoids?
I've read some more info suggesting internal Trans failure might be the underlying problem.
TIA
