I knew on guy at work that had a new 1999 2500 Cummins dually that went through 3 transmissions before they lemon lawed it.
From about 1989 through 2002, Dodge truck transmissions were very [censored]. Dodge went cheap with these transmission because they took a known rock solid design (TorqueFlite 727) that for years was a basic 3 speed all hydraulic operation and started adding extra gears and electronic shift solenoids. To cram the extra stuff in the case, they had to make other stuff lighter and smaller, thereby weakening the design.
Not until Daimler took over, did they start to get back to designing a build more decent transmissions.
Which is why there are adapters and stand-alone systems out there to put the 4R100 and 5R110/5R120 behind them.
Great engine, decent trucks. Really bad trannies (back then).
