Please help diagnose problem.
I have '93 F-150 w/4.9-6 w/auto trans. Approx 220K miles. Well maintained, runs great, uses no oil. But it's acting up during shifting. As engines reaches shifting RPM, it acts like it labors to shift. Usual engine noise seems get higher pitch, w/some vibration while going into 2 higher gears. Does it mostly during 1st few minutes driving. Then smooths out and only does it occasionally.
Took to my Ford mechanic, you says he doesn't think it's the tranny. No idea what it might be. Anyone ever had same experience? What was it?

First thing to do is check it for trouble codes, even if the light isn't on. And see if it gets a pass "111" for the KOEO test.
That might give the clues needed to go on.
If you're not sure how to do so see here> Ford Fuel Injection How To Run a Self-Test
