US Shift Quick 4 stand alone transmission controller
Anybody have any experience or knowledge using this product? Recommendations good or bad? Does it really replace all the factory faulty transmission controls?
This would be on a 92 E4OD behind a 7.3l diesel. My transmission has giving me so much grief I'm about ready to swap in a ZF5. Missed shifts, light blinking, etc. next day it's fine again. Then back to crazy shifting or maybe not. I believe the trans it's self to be in good condition. Cause when it works it works great, nice firm shifts, doesn't slip etc. Believe it to be a faulty computer or sensor maybe a wiring problem. Which I can't find.
My question is can I really just get one of these controllers and bypass all the factory junk?
Those have a great reputation. No problem there. That said, you could spend all that money and have the exact same problem if you have a valve body, converter, or sensor(s) or solenoid pack issue.
I thought those controllers were for transmission & engine swaps into older vehicles? If your truck came with the engine and transmission originally just fix the problem or go to a different transmission.
I had a similar predicament when my C6 and VRV went out. I did all the testing I could and found that both the transmission and VRV needed a rebuild. I considered a manual swap and a reverse pattern fully manual valve body. Now, my truck shifts like a champ. I couldn't do all the work myself. That's why there are professionals.

I just bought and installed one into my 2002 diesel 4R100. It replaces 3 of the factory wiring harnesses - the solenoid harness, the output shaft speed sensor, and the transmission range sensor. You also have to tap into the starter circuitry so that the new controller allows the starter relay to energize when the truck is in park or neutral ("neutral safety switch"), and if you have an OD OFF switch and light like I do and still want it to function, then you need to hook up those wires to the new transmission controller as well.
What I didn't think about until after I installed it is that unless you chip your PCM and tell it to stop trying to talk to your transmission, then you're going to permanently have 9 Check Engine light codes popping the light on the dash because it can't "see" the transmission anymore and thinks that's a problem.
You could run a manual trans controller with your '02 and solve that issue, I'd think?
If you mean swap in the PCM from a truck that had a manual transmission, then yes, assuming I could find one that was guaranteed compatible. Idk much about PCM swapping, but I think I remember reading that you had to check VINs because inter-compatibility was limited, but I could be thinking IDMs instead.
