96 GMC Jimmy code 1886. Changed both Trans solenoids drove good for 50 mi. than back to limp mode Any other ideas of what it could be?
The TSB about the ground wire has been fixed as well. When my husband had the pan off there was no burnt transmission oil, metal, or any signs of wear to the transmission. I had the cruise control on when the rpms went crazy and it went back to limp mode. Today I drove it and it drove perfect until it heated up and than went back to limp mode again. Confused.
