The failure pattern owners describe
The 2005 Dodge Ram 2500 diesel automatic transmission shows a pattern of unintended Park-to-Reverse shifting. Owners report putting the transmission in Park, then having the vehicle roll backward despite the shift lever indicating Park. The problem occurs both with the engine running and off. In several incidents, the shift position indicator (PRNDL display) either fails to illuminate or shows Park while the transmission is actually in Reverse or another gear.
Owners describe incidents ranging from minor property damage to injuries. One driver was hit and pulled a leg muscle. Another sustained arm injury while trying to stop a rolling vehicle. Multiple incidents involved the vehicle rolling into structures, fences, parked vehicles, and trailers, sometimes with the owner standing nearby.
Dodge's recall remedy—a door-open/engine-running alarm (05V462000)—is widely criticized as ineffective. The alarm only sounds when the driver's door is open and the transmission is out of Park, missing situations where only the passenger door opens or when the vehicle rolls with the engine off. Owners report the alarm failed to activate before they exited the vehicle, and some trucks continued rolling backward even after recall work was performed. Dealers could not duplicate the problem on multiple attempts. One owner says a Chrysler investigator deemed the vehicle "unsafe" after the recall repair, calling the alarm a "short-term repair."
Some owners report long delays in transmission response when shifting into gear (4–10 second lag before engagement). Others describe the vehicle shifting out of gear unexpectedly while driving or inadvertently selecting Neutral over a speed bump. One owner notes difficulty shifting into Park itself.

Failure modes owners describe
Park-to-Reverse transmission slippage
Transmission shifts from Park into Reverse without driver input, sometimes with shift position indicator failing to illuminate or showing Park when transmission is actually in Reverse. Vehicle rolls backward, occasionally striking people, property, and other vehicles.
When: At rest, engine running or off; occurs intermittently, sometimes within seconds to minutes of parking
Symptoms owners cite: Vehicle rolls backward despite shift lever in Park detent; Shift position indicator (PRNDL) not illuminated or illuminated for wrong gear; Driver must visually confirm Park position before trusting vehicle; Vehicle rolls on level and inclined surfaces
Repairs/costs cited: Recall 05V462000 involved software modification to add out-of-park alarm; owners report alarm sometimes fails to activate or activates too late. Dealers unable to duplicate problem on multiple visits. One independent investigator determined vehicle 'unsafe' after recall work.
Recalls/TSBs owners mention: NHTSA Campaign 05V462000 (2006): Install out-of-park alarm (horn sounds when driver door open, engine running, transmission out of Park). NHTSA Campaign 07E009000 also references lever and linkage issue. Manufacturer told owners problem is 'normal' or 'as designed' and refused repairs under warranty in some cases.
Shift position indicator malfunction
PRNDL display fails to illuminate around any gear position, specifically Park or Reverse, leaving driver uncertain of actual transmission state even when shift lever is in detent position.
When: Intermittent; occurs at rest with engine running
Symptoms owners cite: Position indicator marquee not illuminated; No visual confirmation of current gear; Driver must physically verify Park position by feel
Repairs/costs cited: Recall 05V462000 mentioned but did not address root cause; dealers changed transmission parts on first complaint in 2006 with temporary improvement, then problem recurred.
Recalls/TSBs owners mention: NHTSA Campaign 05V462000; manufacturer stated failure 'normal' and declined further repair in some cases despite prior warranty coverage.
Delayed transmission engagement
Transmission hesitates 4–10 seconds after shifting into gear before power engages; engine revs, truck rolls, until transmission finally catches. Referenced in service bulletin but manufacturer refused to authorize repair.
When: After shifting into gear from Park; occurs at low mileage (~24,000 miles reported)
Symptoms owners cite: 4–10 second delay before transmission engages; Engine revs up while truck continues rolling; Vehicle finally catches into selected gear
Repairs/costs cited: Service bulletin #2101605 exists; dealer stated consumer not covered by bulletin despite acknowledging problem exists. Manufacturer claims delay is acceptable.
Recalls/TSBs owners mention: Service bulletin 2101605 available but manufacturer (Dodge/Chrysler) refused to approve repair; stated 4–10 second delay is normal operation.
Transmission shifts out of gear while driving
Transmission unintentionally downshifts to Neutral or shifts to incorrect gear during normal driving, causing loss of power and control.
When: While driving at highway speeds (~57–80 mph) and at low speeds; in one case after driving over speed bump at <60 mph
Symptoms owners cite: Automatic downshift to Neutral without driver input; Inability to shift into desired gear; Vehicle coasts when Neutral engaged; Abnormal noise under vehicle
Repairs/costs cited: One owner reported entire transmission replacement required (28,300 miles); repair covered under warranty. In other cases involving drive-shaft separation, rear assembly, transfer case, CV units, ball joints, and control arms required replacement.
Recalls/TSBs owners mention: NHTSA Campaign 14V796000 (Power Train) issued; parts availability delayed, no estimated completion date given.
Tow/Haul button malfunction
Tow/Haul button engages wrong gear selection, particularly problematic when towing trailer downhill; vehicle accelerates instead of downshifting for engine braking.
When: While towing trailer on downhill grade
Symptoms owners cite: Vehicle speeds up instead of downshifting; Difficult to control descent while towing; Wrong gear selection for load and grade
Repairs/costs cited: No repairs made; dealer stated vehicle designed and operating correctly.
Recalls/TSBs owners mention: Dealer inspection; no manufacturer response documented. Told customer behavior is by design.
Driveshaft separation
Rear driveshaft separates or fails at high speed while driving, causing sudden loss of power and crash. Associated secondary failures in rear assembly, transfer case, CV joints, and suspension.
When: While driving 57–80 mph; failure mileage 173,000–270,000 miles
Symptoms owners cite: Abnormal vibration at highway speed; Loud noise under vehicle; Driveshaft dislodges from vehicle; Vehicle crashes into wall or coasts to shoulder; Secondary damage to transfer case, CV joints, universal joints, fuel lines, brake lines
Repairs/costs cited: Technician diagnosed need for rear assembly, front transfer case, both front axles, CV units, ball joints, and control arms replacement. Vehicles not repaired in some cases.
Recalls/TSBs owners mention: NHTSA Campaign 14V796000 (Power Train) issued; parts not available as of 2015, no estimated timeframe given.

The clutch pedal connecting rod to the clutch master cylinder separated from the master cylinder. It happens if you bump the pedal backwards with your foot going for the brake. Then you can't push in the clutch! You have to pull it out of gear pull over and put the rod back in. Clutch pedal comes back real far and causes this! This happens when driving and may cause a accident not being able to…
