E4OD shifting
I have a 94 E350 with the 460 and the E4OD trans. that has only 30K on it.
Last weekend I took it on a 250 mile trip (one way) and it ran beautiful until the final steep hill to our vacation house. It started vibrating when it went to down shift and wouldn't pick up any speed, the OD off light was blinking. When I pushed the OD button and it cleared right up. Ran beautiful until I tried to climb that same hill again (same thing happened). It showed the same symptom when I tried to back up a steep driveway during the same trip.
Now it no longer does the vibrating but now has harsh/firm up shifts. Downshifts are smooth though, but shifting into reverse and drive are bit clunky too.
The codes I pulled were KOEO 212 and 668. After I erased the codes the 668 didn't come back. But I did change the MLPS to the new updated one from Ford and its still doing it.
I also found the 40amp mega fuse under the hood was blown too, related? Could a 1/2 qt over filled trans. cause this now too? In NH I added some fluid thinking it was low because I could not get a clear reading on the dipstick but I think the level was up there.
