Well went and picked up truck at the exhaust shop today. went to drive it home but the tranny is stuck in limp mod....... its a 93 chev dually with a 6 liter. i installed a floor shifter but even if i go threw gears there all 2nd any help would be great. I am waiting for my buddy with a code reader to come by and look. will post any info it gives me
p1258gm
p0200
these are the codes that are showing
I dont have a clue but i once burned up a bcm by welding a seat bracket while it was on the car. Maybe the some how fried the pcm when they welded the exhaust.
Test for ignition at trans connector

I have the p0200 codes for each bank and i did some research and alot are saying a pcm issues as i erase it, it comes back instantly. i have checked over all wiring. Also did fix the over heating issue. replace thermostat and let it idle for a while, seamed to be all good
well spoke to Current last night and got tranny working, they wired it for a 93 which my truck is but if they followed the harness i sent them they would have known my tranny has been wired for a 94 4l80e..... also did a few test on injector circuit and there gonna be sending a new computer for the truck. Cant wait as right now when it gets in the high rpm she fly"s
