Fix Dodge diesel stalling problem
If you own a Dodge vehicle with a diesel engine and the 48RE transmission and encounter a situation where the engine partially stalls and then RPMs increase, the problem is most likely a partially restricted Torque Converter Clutch solenoid. The increase in RPMS may make the vehicle hard to stop. Another symptom you’ll notice is firmer than usual shifts following the stall/surge event.
Computer strategy on these vehicles includes increasing RPMs when the TCC is applied to prevent engine stalling. The cause of the problem may be a mechanically restricted TCC solenoid that causes it to apply in 1st gear. Fix the problem by replacing the Lock-up and Overdrive solenoid assembly as a unit.
