E4OD shifts hard

I put a used E4OD in my truck that the guy told me had 3000 miles on a rebuild but it shifts hard like it just drops into gear it isn't nice at all what can be causing this?

Is the OD light flashing ?

Is it a hard shift or a firm shift ?

OldWoodsDiesel is gaining momentum as a positive member of FTE.
before i swapped to the zf5 my truck would shift hard whenever it rained. turned out the sealing gasket in the connector on the RH side of the tranny was bad and letting water in. you might check and make sure you connector there is seated right. it looked like it was quite easy to get that seal all jammed up inside so that the pins didnt engage right.

just a thought.

Does the OD OFF light work when you press the button? Does the light flash?

The OD light isn't flashing or anything and the guy told me he built it back to stock and ill have to check but my old transmission never shifted firm even when i could only go 30 mph i put transmission additive in it then it shifted nice for a little bit but then it came back and the transmission oil seems fine

OK, does the OD OFF light work when you press the button? I'm persistent, I will keep asking the same question over and over until I get an answer.

Since the light isn't flashing this means there are no codes stored. That means there is something mechanical causing the harsh shifts. Most likely it has a shift kit that is doing it.
