P0872 on RAM
Transmission Fluid Pressure Sensor/Switch 'C' Circuit Low
P0872 on RAM vehicles indicates transmission fluid pressure sensor/switch 'c' circuit low. Au7o has documented this code across 1 RAM model — most commonly on 2500. The transmission fluid pressure sensor/switch 'C' circuit voltage is below the expected range (too low / shorted to ground). Typical repair costs on RAM range from $1,500 to $4,800, depending on the specific model and root cause.
Common Causes of P0872
- •Sensor signal shorted to ground
- •Faulty pressure sensor/switch C
- •Corroded/damaged connector
- •Internal TCM fault

- 68RFE Torque Converter Shudder and TCC Failure2007-2024
The 68RFE 6-speed automatic behind the Cummins is prone to torque converter shudder and lockup failure. The factory converter's clutch material and heat control are marginal for the Cummins' torque, so the torque converter clutch (TCC) chatters, slips, or refuses to hold lockup, felt as a low-speed vibration like driving over rumble strips. The TCC regulator valve wears its bore in the valve body, making apply pressure erratic. The resulting heat contaminates the fluid and cascades into planetary and clutch-pack damage. Heat is the number-one killer, especially when towing; fluid temps regularly over 200°F accelerate failure.
