05/06 lbz ccsb 4x4 without front driveshaft., dsp5 switch for efi, but its unknown whos tuned it, lift pump, ATS trans, rebuilt clutches, all new solenoids, new TCM, fluid flushed about 4 times, tcm connector re wired. Looked for bad wires, or rubbing issues. Havent ohmed anything yet but figured it couldnt be that difficult or time consuming but its now costing me and my pocket.
The owner is a farmer that is about to throw, what i think is a good tranny away when its not needed, everything stated above and probably more.. has not fixed this exact issue stated below.
limps after reaching 170 degrees, il be going down in gears, coming to a stop sign and once it hits 2nd or 3rd, CEL comes on and its now in limp mode. Reset the codes, drive down the road through all gears, boom does it every time coming to a stop, almost.. im thinking its either
1. Customer keeps giving me "premium ATF, ORIELLYS BRAND"
2. the pressure switch on the valve body.
3. Its not really a shift solenoid stuck off.
I just want this truck out of my shop and good to go for the owner. I own 2 lb7s, one lly, never came across this issue and it seems not a lot of people have. Doesnt throw any other codes. So if i can get pointed in the right direction, im donating a 100$ to whomever directs me in the way of fixing this issue, or to any charity that they choose(other than their own).
Im working with a SNAP ON SOLUS ULTRA on 17.somethen and love for duramaxs.
