Hello,

I have a 1992 F-150 4x4 with a 5.0 and an E4OD Transmission. The transmission started leaking from the front so we took it out and replaced the front pump seal. Since then the tranny will not shift into 3rd gear. There are two electronic connectors on the transmission and I have made sure that they are attached well. It seems that it trys to shift from 2nd to 3rd but it never quite makes it. The only thing I can think of that could be related is this. When I took out the tranny, I left it attached to the transfer case. While out of the vehicle I disconnected the transfer case from the tranny, but at first I seperated it from the wrong place. About 9inches too close to the tranny and I noticed that a rod was connecting it with a spring attached. The spring came out and I placed it back in. I’m not absolutely sure if I put the spring in correctly. The truck seems to drive fine up to shifting into 3rd. I replaced all of the fluid and it is at the proper level. Any help would be very appreciated as I miss my 4x4. Thank you, Sean

Small update: Thx to a friend for some documentation on the E4OD I was able to determine that the TPS sensor was bad which is known to put the transmission into (FMEM) Failure Management Effects Mode. I replaced the TPS sensor and reset the main computer. I don't know if the transmission is in FMEM or if resetting the main computer would take it out. But after test driving it, I still do not have 3rd gear. Although it idles better, lower, and stopped stalling out. Still any info is much appreciated, thx, Sean.

Another update, heard that a wire can be broken in the steering column harness, remembered that my OD light doesn't work. Tested the OD switch with a voltmeter it is working fine, the light merely went out. Replaced the stock red led with a new blue one. Switch works fine, light too, but still no 3rd gear.

Additionally, heard that the 2 plugs that connect to the transmission could have problems.
I looked under the truck with a light and saw that the plug on the passengers side had bare wires and were even shorted out in some cases. I took the harness out, separated all the wires, filled them with hot glue to prevent further shorts. Hooked everything back up, reset the computer and still no 3rd gear.

If anyone has any clues based on this further info please, please let me know.

Thank you, Sean

 

Most tranny shops have what is called a "breakout box". its plugged into the tranny and then can be shifted thru the gears by flipping switches. This will tell you if the problem is in the tranny or the trucks wiring.
