good afternoon.
Yesterday my truck was running fine, this morning I got off work and went to start my truck. as per usual, I let the FASS cycle and then I started the truck. I let it sit long enough to go in and grab a 5 gallon bucket of ice to add to my cooler. When I went to move the truck ,it died. started again and let sit a second, as soon as I shift to drive it had rpm fluctuations and seemed like it was going to die. Idles perfectly until shifted to drive and try to move. I checked the water separator on my FASS as we recently had scare of a hurricane here and I got some bad fuel last time we had a hurricane. that wasn't it. it idles perfectly fine, as soon as I shift to drive it would act up. eased onto the road and it accelerated fine (I only live about 7 minutes down the road) but would not go into overdrive. got it home, unplugged batteries after getting and clearing codes with smarty touch, and left it for over an hour. batteries are both odyssey batteries less than 3 months old and both check good. transmission was fully rebuilt in the end of 2017 with a kit from PDD including valve body, flex plate, triple disc billet converter, etc. to hold up to the engine mods. the three codes I got are P0712, P0868, and P2769. p2769 has not come back after I deleted the codes with the smarty and drove it down to the end of my road and back (about a mile and a half dead end farm road), but it hesitates like crazy when starting out and acts like its going to die, after that it gets up and goes almost like normal just can't feel it lockup or go to overdrive. 48RE in a 2004 vin c 3500 srw laramie 4 door. mods on truck are 4" bds lift, 35x12.50r20 tires, smarty touch with custom tunes, industrial injection r2 125 hp injectors, fleece powerflo 750 CP3, Fass 165t, fuel filter delete, upgraded intercooler, arp studs, pusher mega air intake with cross-air, pusher mega intercooler piping, fleece performance cheetah VGT with a Borg Warner s475 atmospheric turbo on a pusher compound setup, deeper oil and transmission fluid pans, oil bypass, coolant bypass and flopro stainless straight pipe exhaust. Transmission was upgraded as mentioned (PDD 650 hp with triple disc billet converter) with no problems since (broke the input shaft before the upgrade by pulling my trailer through some mud, I know not smart). only work done in the last 9 months was replacing front wheel bearings and front and rear brakes along with oil change. transmission fluid level is correct with nice clear red fluid. Truck runs amazing 99% of the time, tuning is not very aggressive. any help is greatly appreciated.
