95 Blazer with P0752 DTC

[fatboyspur]

Trans in limp mode. DTC P0752 keeps coming back for 1-2 shift solenoid.

Have replaced 3 times now. Blazer shifts the best for 1 or 2 days, then back

to limp mode and SES light on. This has been a recurring problem for 2

months now , since tranny was rebuilt. Reverse had gone out. I think it is

electrical problem, when it shifts right, it does exactly as it should. Have replaced

all solenoids, and wiring harness in tranny. Any suggestions would be

appreciated!

Check the external electrical connector to make sure its seated correctly and the pins are not loose or bent
