Hey first post here and I am hoping you guys can help me out!
I'm a new owner of a 1994 4x4 f250 factory turbo 7.3 idi and I am having issues with the transmission...
With the selector in drive, I have no overdrive or what feels to be like 1st gear. If I manually shift it from 1 to 2 it does not shift, it will only shift again if I put it into drive, shifting into what I would guess to be third gear. Reverse works fine.
I checked the tps today, I have 1.2v at idle and 4.2v at wot, so that seems to check out. Ive read shorted out brakes could stop the torque converter from locking up. My cab brake light was unplugged when I bought the truck because the buttons on the door do not set off the dome light, but I plugged them back in for a test drive and nothing changed.
I've also read the speed sensor on the rear axle could be causing this, I have not checked it yet but my tachometer and speedometer are working, however cruise control is not.
The OD light was flashing about a week ago, but I disconnected the battery in an attempt to get it to reset something and it has not gone on since, so I am not sure if I can get a code read.
The only other things I can think of to check are the speed sensor or electrical connections at the transmission. Or am I wasting my time and the tranny is shot and I just need a rebuild?
Thank you
Edit: Forgot to add, fluid does not smell burned, and I checked any fuses related to the transmission, all are good.
