Power Control Module removal
Can the PCM be removed from a 92 7.3L IDI W/ an E4OD, if the trans is adapted to an aftermarket controler?
What got me thinking about this is my truck has 350K+ miles, the motor has been replaced & the trans was rebuilt. The Trans is acting strange. Shifting really early, smooth shift from 1 to 2, slamming from 2 to 3, then not wanting to shift into OD, reguardless of speed. With the price of fuel these days, I need to get this thing to act right.

I checked the FIPL last night with a volt meter, got 1.16 vdc @ idol, 4.78 vdc @ WOT (engine not running). The O/D light has not worked on this truck since I got it, so I can't tell if the button is pressed or not. The tach and spedo are both steady while running. I loaned my code scanner to a friend. I didn't think you could do anything with an older vehicle except KOEO/KOER scans. I guess I'll have to get it back and try it.
I did have another situation that I have lived with for a while, when driving down the highway back before the trans stopped going into O/D, if I engaged the right turn signal the truck would shift out of then back into O/D. The same would happen when signal canceled.

Update...
I checked the FIPL again, and reset it to read 1 vdc to ground with the throttle closed. I also ran a KOEO scan, and it came back with a 99 code.
Since there is no "check engine" light in the dash, i am asuming the O/D Off light is the indicator, since after I replaced the switch in the end of the shifter (because the O/D light was not working at all), the light started to flash. I did the KOEO test and cleared the codes, the light quit flashing. The truck still will not shift int O/O, but the other gear changes are not as violent as they were. I bought another FIPL sensor but am not sure weather or not to change it, since the one in the truck seems ok. I might as well change it, since I can't return it to the Ford dealer.
