I had major slipping and engagement issues with my previous transmission so I replaced it with a used unit with 150k miles.
My current (and previous) transmission would shift from 3rd to 4th, then prematurely shift into 5th. I have to lug the engine in 5th to shift down, which jumps back to 3rd then to 4th with an early shift to 5th. This is annoying while driving on highways with any grade.
I noticed that the transmission will stay in 4th when the engine is cold. Not sure if this is related. I know 4th is there as there’s no slipping, but it doesn’t like sticking around long enough to make an efficient shift into 5th and requires too much throttle to shift down from 5th (skips 4th) and screams in 3rd.
I’ve replaced the filters and fluid.
No check engine light
Any help is appreciated!
