All 4 Known Issues
The 2007-2018 RAM 3500 with the 68RFE 6-speed automatic transmission suffers from premature failure when towing heavy loads (over 10,000 lbs). The 68RFE is a derivative of the older 545RFE and was not adequately engineered for the torque output of the 6.7L Cummins. The overdrive clutch pack, solenoid pack, and torque converter are the primary failure points. Overheating during sustained towing destroys the clutch packs and warps the valve body. Many trucks experience complete transmission failure between 80,000-150,000 miles if used for regular towing. Rebuild cost: $3,000-5,000. Built/upgraded transmission: $5,000-8,000.
Common Symptoms
- Transmission slipping under heavy load
- Flare between 3rd and 4th gear
- No 3rd gear or no overdrive
- Transmission overheating warning while towing
- Harsh or delayed shifts
- Check engine light with transmission codes
- Complete loss of forward or reverse gears
How to Fix
For minor issues: Complete fluid and filter change with Mopar ATF+4 (68218057AA) and solenoid pack replacement ($400-800). For overheating prevention: Install an auxiliary transmission cooler and keep temps under 220F. For rebuilds: Use a reputable heavy-duty builder (SunCoast, Randys Worldwide, BD Diesel). A properly built 68RFE with billet shafts, upgraded clutch packs, and triple-disc torque converter ($5,000-8,000) will handle 800+ lb-ft of torque. For 2019+ trucks, the Aisin AS69RC replaced the 68RFE.

The RAM 3500 equipped with the Aisin AS69RC 6-speed automatic transmission experiences torque converter shudder, overheating when towing, delayed shifts, and premature wear. The torque converter lockup clutch develops a shudder at light throttle and highway speeds. When towing heavy loads (10,000+ lbs), the transmission temperature can spike rapidly, triggering limp mode. TSB 21-013-19 addresses torque converter shudder with updated fluid and converter. The AS69RC uses a specific Aisin fluid (Mopar 68218058AA) and using incorrect ATF+4 causes accelerated wear. Converter replacement runs $2,000-3,500.
Common Symptoms
- Shudder or vibration at highway speed (40-60 mph)
- Transmission overheating when towing
- Delayed or harsh shifts
- Transmission temperature warning light
- Limp mode activation while towing
- Slipping sensation during light acceleration
- Torque converter lock/unlock cycling
How to Fix
For shudder: First try a complete fluid change with Mopar Aisin-specific ATF (68218058AA) - NOT standard ATF+4. If shudder persists, torque converter replacement is needed ($2,000-3,500). Check TSB 21-013-19 for updated converter part number. For overheating: Install an auxiliary transmission cooler ($200-400, B&M or Derale) and reduce towing speed. Ensure the external transmission filter (if equipped) is clean. Some 2013-2018 trucks qualify for extended warranty coverage on the Aisin transmission.

The RAM 3500 4x4 with the AAM (American Axle Manufacturing) 9.25 front axle experiences premature front axle seal leaks and u-joint failures. Differential fluid leaks from the inner axle seals, contaminating the front brakes. The front axle u-joints (Dana Spicer 60) wear out prematurely, especially on trucks with oversized tires or that are used for snow plowing. Symptoms include grease on the inner wheel/brake area, clicking/popping when turning in 4WD, and vibration. TSB 03-004-18 addresses front axle seal replacement procedure. If the leaking oil reaches the brake pads, both pads and rotors must be replaced.
Common Symptoms
- Gear oil leak on inside of front wheels
- Contaminated front brake pads (oil soaked)
- Clicking or popping noise when turning in 4WD
- Front end vibration in 4WD
- Grinding noise from front axle area
- Differential fluid level low on inspection
- Reduced braking performance on front wheels
How to Fix
For axle seal leaks: Replace the inner axle seals on the affected side (Mopar 68216218AA, $25-50 each) and inspect the axle shaft for wear at the seal surface. If the axle shaft is grooved, install a Speedi-Sleeve repair sleeve ($30). If brake contamination occurred, replace front brake pads and rotors ($300-500). For u-joint failure: Replace with Spicer Life Series (SPL55-3X) u-joints rated for 3500-class loads ($50-100 per joint, 2 per side). Total repair: $400-1,200 depending on extent.

The RAM 3500 6.7L Cummins equipped with the integrated exhaust brake system experiences failures of the VGT (Variable Geometry Turbocharger) actuator and exhaust brake solenoid. The exhaust brake uses the VGT turbo vanes to create backpressure for engine braking while towing. The electronic actuator (Holset HE351VE/HE300VG) sticks or fails due to carbon buildup, causing loss of exhaust brake function, reduced turbo performance, limp mode, and DTC codes P2263 or P006A. TSB 14-001-21 addresses VGT actuator calibration. Actuator replacement costs $800-1,500; complete turbo replacement is $2,500-4,000.
Common Symptoms
- Exhaust brake not engaging or weak braking effect
- Check engine light with turbo codes (P2263, P006A, P0299)
- Reduced engine power / limp mode
- Black smoke from exhaust under acceleration
- Turbo whistle or surge at idle
- Slow turbo spool-up / turbo lag
- Exhaust brake light blinking
How to Fix
For sticking actuator: Remove and clean the VGT actuator and turbo vanes of carbon deposits. Actuator exercise procedure via wiTECH can help prevent sticking. Check TSB 14-001-21 for actuator calibration procedure. If the actuator motor is failed, replace the electronic actuator assembly ($800-1,500, Holset 5497296 or 5610723). If turbo vanes are severely carboned or damaged, complete turbo replacement is needed ($2,500-4,000). Regular highway driving helps keep vanes clean; trucks that idle excessively build up carbon faster.
