I was wondering if anybody came across any shifting issues and Torque converter engagement issues after reinstalling an engine. I have a 1999 Dodge Ram 1500 4x4 with the 5.9 Magnum engine. I just finished putting my engine back in the truck after changing the crankshaft, bearings, intake manifold gasket and a variety of things. I initially had a stalling issue when the transmission was in Park and that was resolved after replacing the TPS. Before the sensor was changed, I also noticed a issue which I suspect is the torque converter engaging. I hoped this issue would go away, but it hasn't.
So the issue I am having is when the truck gets up to about 45 to 50 MPH with the gas pedal lightly pressured, I feel a bump in the truck and through the gas pedal. If I attempt to accelerate faster while approaching and passing the 50 MPH mark, the bump is more severe. The other thing I noticed is that while traveling about 55 MPH or so with the right foot holding the gas pedal down, when I press the brake pedal with my left foot, the engine RPM's change and then after I let go of the brake pedal, it goes back to where it was. This part is a smooth transition.
The inital lockup doesn't seem right. I am wondering if the throttle needs adjustment or maybe the transmission cable. My transmission guy I talked to thinks it is the Dacco torque converter and believes it is defective. I am leaning toward the idea that he has a bad taste in his mouth for the Dacco brand. Any help would be Awesome.
