E4OD nitemare!
92 E4od shifts from 2 to 3,4. That quick.Truck shakes all over.Ihave done 4 stall tests, chandged main valve body, mlps, solenoid pack, psom. I have unplugged solenoid pack and have 4th in Od, 2nd in 2nd and first. Did stall test in reverse. no slippage. Line pressure is good. It shifted from 2nd to 4th as it should. Transmission was rebuilt by me 1 year ago.

4th to overdrive is impossible. This is a four speed transmission, with fourth gear being overdrive. It can't shift from fourth to fourth. I think you're confusing the torque converter lockup for another shift.
My guess is that you have a failed shift solenoid. But there is so little good information here this is no more than a guess.

I am having trouble replying . Will do this again. You sound like just the one for the task. About 2 months ago, the trans acted like it was pulling out in second gear. Symptoms were sporadic. As it warmed up it would do this.sometimes it would neutral out for a second, then jerk to low gear. Shifting to neutral, then back to low, you had low gear. manual low always was there.It no longer does this. Now it shifts 1-2 , 2-1 perfectly.It will shift 1-2, barely catch 3rd, straight to 4th. Truck starts to shake really bad when it does this. if you light throttle it, it is pretty good.if you let off the 3 shift is there, so is fourth, then overdrive. Before the jerk felt like a bad plug or wire. now its constant shaking. sometimes when you use tcs, its jerks in and out, then works ok. if you unplug rear speed sensor, and don't crowd it, it shifts fairly well. all gears are there, even overdrive. there has been no slipping . It will do this even with od turned off.

Hi, I'm not trying to be mean or be a smarta $$, but this thread is difficult to understand.
This has no meaning to anyone but you. What does this mean?
You don't seem to understand the difference between converter lockup and shift.
You seem to be thinking that there is a difference between 4th and overdrive, there isn't. 4th and overdrive are the same gear.
Anyone who reads your thread is wondering how you could possibly rebuild the transmission and not understand what it is supposed to do?

Sorry. I don't think anyone is a smarta that takes time to help. It has me confused. I sent Mark an overview of the problem. If you can read it, it might explain somewhat. Thanks

Turn off overdrive. Start off with the shift lever in 1. At 10 MPH (more or less) move the shift lever to 2. At 20 MPH move the shift lever to OD. What does the trans do?

I just drove the truck and it shifted very well, ice cold. about 40 degrees here. first 2 times through the gears ok. third time it started the shaking. overdrive light on it thumped down from od light off thumped back in. next time i did it there was no thump, fairly smooth.

Maybe it’s just me but I don’t know what “Same thing” means.

So with the overdrive turned off it still shifts to overdrive? The test I asked you to run should start in 1, go to 2 when you move the shift handle to 2, and go to 3 when you move it to OD. If it is going to overdrive with the OD OFF light on, there is more going on here than I understand. I don't know where to go from here.
