Do I need to replace my Dodge 3500 Truck transmission?

Dodge trucks last appeared in 2008, when Dodge spun off its truck line off into being an independent division.

The 68RFE transmission is primarily used in Dodge trucks, including the 1500, 2500 and 3500 series. These trucks are built for heavy-duty use like towing and hauling, and require a transmission that can handle the strain. The 68RFE transmission is well-suited for these applications, thanks to its solid design and torque capacity.

Despite its reputation for strength and durability, the 68RFE transmission can develop problems. One common issue that can occur with the 68RFE is overheating. Overheating may be caused by several factors, including towing heavy loads, driving in extreme heat, and plain old improper maintenance. Overheating can cause many different follow-on issues, including slipping gears, burning smells, and maybe even complete transmission failure.

Another frequent problem that occurs with the 68RFE transmission is torque-converter shudder. Torque converter shudder is often caused by a failing torque converter clutch. The torque converter is designed to transfer power from the engine to the transmission and can exhibit a shaking or vibration when it’s not working properly. This can also cause damage to other components inside the transmission, such as the planetary gears.

Clutch failures are also a known issue with the 68RFE transmission. Clutches are designed to wear out over time, but premature failure can occur due to a variety of factors, such as overheating, contamination, and bad driving habits. When the clutch fails, it can cause slipping gears, delayed engagement, and even complete transmission failure.

On some Dodge transmissions, the brake transmission shift interlock pin can sometimes get stuck in the open position. This allowes the truck to be put into gear or slip into gear without depressing the brake pedal.

That caused some trucks to jump out of Park and into Reverse or Drive and roll away while the truck is stopped and the engine is shut off. In other model years, the pin might get stuck closed and prevented the truck from being shifted out of gear at all.

The 2023 Dodge 3500 Diesel comes equipped with the 68RFE six-speed automatic transmission. This transmission can handle the tremendous torque of the 6.7L Cummins Turbodiesel I6 engine. The same charicteristics apply to the 8-speed automatic 8HP75-LCV transmission available on the gasoline powertrain. When equipped with this heavy-duty 6.4L Hemi V8 engine, the 410 hp and 429 lb-ft of torque, matched with the 8-speed transmission, provide smooth driving performance while delivering robust towing and payload capacities.
