I have a 1995 F150 with a 5.0, 4spd overdrive automatic. My problem started this past winter. Truck sits outside in driveway, no garage. We had a brutally cold snap for about a week here, and it wasn't started nor moved. When I did go to the store, the check engine light came on, and the truck wouldn't shift past 2nd gear. I broke out my el cheapo code reader for OBD1 and No codes. Still wont shift past 2nd gear. Starts, runs, has plenty of power just not past 2nd gear.
Can someone suggest what to check besides the tranny pluid as I already did that and it's fine.
Oh yea, I almost forgot, this is a 5 yr old replacement, rebuilt tranny.
