• Description:

  Restore Your Transmission’s Intelligence and Shift Precision
  Your automatic transmission relies on split-second data to decide exactly when to shift. The Genuine Mopar Transmission Input Speed Sensor (04800878) is the essential electronic "eye" that monitors the rotational speed of your input shaft, feeding critical data to the Transmission Control Module (TCM). While aftermarket sensors often provide "noisy" or approximate signals that lead to harsh gear hunting, this authentic OEM component is calibrated to the exact electrical frequency required for seamless gear transitions.
  The Genuine Mopar Advantage:

  • Crystal-Clear Signal Accuracy: Engineered with the precise magnetic sensitivity needed to communicate flawlessly with your vehicle’s factory TCM. This eliminates the erratic "limp mode" or hunting between gears often caused by low-tier universal replacements.
  • Superior Thermal Resilience: Built to live in the high-heat environment of your transmission case without electrical "drift." Its premium-grade internal circuitry is designed to withstand millions of thermal cycles without losing accuracy or suffering from internal cracking.
  • Leak-Free Integration: Includes a pre-installed, high-temp O-ring to ensure a perfect, pressurized seal. This prevents the common fluid seepage issues that plague budget sensors and can lead to electrical connector contamination.
  • Plug-and-Play Reliability: As a true factory part, it features the exact connector pin-out and mounting geometry of your original unit. No splicing, shimming, or "forced" fitment—just an immediate restoration of factory performance.

  Eliminate the Guesswork
  A failing input speed sensor doesn't just make driving unpleasant—it can lead to accelerated wear on your clutches and valve body due to improper line pressure. Don't risk a multi-thousand dollar transmission rebuild on a "budget" electronic part. Choose the reliability of the original equipment used by the manufacturer to keep your powertrain running smoothly.
  Common Symptoms This Part Resolves:

  • Harsh or Erratic Shifting: Sudden "clunks" or delayed engagement when moving between gears.
  • Limp-In Mode: The transmission becomes stuck in a single gear (usually 2nd or 3rd) to protect itself from damage.
  • Cruise Control Failure: Your vehicle may disable cruise control as a safety precaution when it can't verify engine-to-transmission speed.
  • Diagnostic Trouble Codes: Resolves common sensor-related codes such as P0715 (Input/Turbine Speed Sensor Circuit Malfunction).
