A buddy of mine has a F250, nothing special just a TS 6 po, intake exhaust, automatic. Today he left my house and called me to say that hes truck would shift to 2nd bt wouldnt get to third. The tranny is a little weak but it hasnt had a problem shifting without a load, slips vary little, the convertr is still strong, when he puts it in reverse it brings the motor down to about 500RPM then lets go after a second or 2. On the 1st to 2nd problem im thinkin the solenoid body, but if there something else i need to check other then fluid level which is good, and viscocity of the fluid(it and the filter were changed about a year and a half ago).It doesnt stink like its burning it doesnt get very hot. But if theres an other thing that i need to look at i would appreciate your .02. Thanx in advance.
