I have a 96 Dodge Dakota SLT magnum 4x4 5.2 with engine swap to 5.9 with a 46RE transmission. I replaced the pressure governor, shift solenoid harness, and torque converter clutch circuit with new fluid filter and gasket. The truck acts to stall out in first and second when accelerating slowly but taking off normally starts the stall out second and third but won’t go into overdrive. My code reader is throwing P0783 - (3-4) shift, but now I’m lost because that should’ve been fixed after replacing the pressure governor solenoid..? Could anyone give me advice on what I should do next? id be greatly appreciated, thanks in advance!
