If you drive a modern Ram Cummins diesel, you already know the engine is virtually indestructible. But if you’ve added power tuning, or if you regularly tow heavy loads through the grueling Arizona heat, you probably know the weak link in the chain: the 68RFE transmission.
The factory 68RFE is notorious for premature failure when pushed hard. From valve body issues and torque converter slip to burned-up clutch packs, it doesn't take much to put your truck out of commission.
We recently had a customer bring their truck into the Power Forge Diesel garage to fix this problem permanently. We didn't just replace the worn-out stock unit; we upgraded it to a beautifully built Randy's Transmissions Stage 2 68RFE.
Unboxing Excellence: The Randy's Transmissions Stage 2
When it comes to bulletproofing a Ram truck, we don't cut corners. Randy’s Transmissions is legendary in the diesel world for building some of the toughest gearboxes on the market.
These transmissions arrive at our garage completely sealed and protected in heavy-duty transit cases, ready for serious action. Before it even goes under the truck, the sheer build quality of the custom-coated red housing and the precision machining stands out.
What Makes the Stage 2 Build Special?
Upgraded Valve Body: Features customized oil paths and robust internals to prevent the cross-leakage that burns up stock clutches.
Heavy-Duty Torque Converter: A multi-clutch billet converter replaces the weak factory single-disk unit, ensuring total power transfer without slipping.
Premium Clutch Packs: Specially engineered friction materials designed to hold higher line pressures and handle aggressive tuning.
The Installation: Built to Handle the Yuma Heat
Installing a high-performance transmission requires precision. At Power Forge Diesel, we ensure everything is dialed in—from measuring tolerances to rewriting the transmission control module (TCM) parameters so the truck learns its new shifting habits smoothly.
Once tucked up underneath the chassis, this unit looks as good as it performs. The freshly built 68RFE mates perfectly to the Cummins engine block, complete with an upgraded, deep-sump Randy’s Transmissions pan.
Why the Pan Matters for Yuma Drivers: This heavy-duty aluminum pan increases fluid capacity and features integrated cooling fins. When you are hauling a trailer past the dunes or working out in the agricultural fields in 115°F weather, keeping your transmission fluid temperatures down is the difference between a reliable ride and a stranded truck.
The Result: Total Confidence on the Road
With the Stage 2 Randy's Transmissions 68RFE fully installed, this Ram Cummins is now completely transformed. The gear shifts are crisp, power delivery is instantaneous, and the owner no longer has to worry about the transmission giving out when climbing a steep grade under load.
