TORQUE CONVERTER CLUTCH (TCC)
The torque converter clutch is hydraulically applied and is released when fluid is vented from the hydraulic circuit by the torque converter control (TCC) solenoid on the valve body. The torque converter clutch is controlled by the Powertrain Control Module (PCM). The torque converter clutch engages in fourth gear, and in third gear under various conditions, such as when the O/D switch is OFF, when the vehicle is cruising on a level surface after the vehicle has warmed up.
If what you're thinking is actually happening (TCC is constantly engaged) ... if it's not the tranny or TC ... all that's left is the PCM and the associated cabling.

Any chance the engine idle needs to be turned up a bit? Grand Ch's take the same tranny as a half ton Ram? No sugar, I didn't know. Do the Durangos or Dakotas have them too?
If it is the PCM, unhook the battery cables, and then turn something on like the 4 way flashers. It will force the electrical system to dump any capacitance. Then reconnect the battery making sure the connections are as clean as possible. See if that makes any difference. Make sure the tranny wiring harnesses are plugged in completely. Sometimes a tab breaks off from prior service, and the wiring works itself loose.
And are you getting any codes? Like 37 maybe?
Good luck with your ride.
I make horsepower and torque the old fashioned way. MECHANICALLY. There is no other way. Chips go with dips.
