My 2002 e350 has been shifting real hard here lately. It seems to not want to shift then when it does it seems forced, the truck has 82000 miles on it. Has anyone experienced this before on these trucks? I see no sign of leaks anywhere so I assume the fluid is alright. Any ideas?

Let the vehicle warm up and check the trans fluid while it is running. Also see if it is brown in color instead of a clean, red color.

You may get lucky by dropping the trans pan, replacing the filter and gasket, filling with new fluid (Check what type), and seeing if that helps. If, not, then it's tranny time.

i have a 95 f150 that does that too but it downshifts hard also. was told speed sensor, nuetral safety switch, fluid, filter, done all that but have noticed that it only does it when oil preassure gets low then seems like it sets a code in computer to shift like that. most of the time its fine after a few hours of not running. hope it helps some also no codes come back from diagnostic (spell)
