When driving on a flat road no real issues, except when I try to accelerate hard. It won’t shift and stops trying to accelerate past 3k rpm. Up hill, regardless of weather, temp, ac on or off, it won’t accelerate past whatever speed I’m going. For example, let’s say I’m going 45mph, once I hit the hill, it won’t go past 45mph and may start losing speed.
Replaced trans filter, and one of the solenoids, new fuel filter, new range sensor (replaced twice, once with an generic brand the second time with motor craft part). Ironically enough, the problem started shortly after replacing the range sensor.
Just need some ideas. My Expy may be old and ran thru (got it from Copart) but solid otherwise
