F150 Hard Shift
Not real sure which tranny I have but just recently I took my 95 F150 with 59,000 miles on it from Orlando Florida to South Carolina. After being on the road for about an hour it began to shift hard between gears. I do not have cruise control, but it has the hi/lo button on the shift lever. I began noticing the hard shift whenever I had to go into and out of passing gear. Then again whenever I stopped at a light and it up-shifted. If it were a non computerised transmission, I would suspect the modulator valve. When I put my code reader on, there are no indications. Any ideas will be appreciated.
