Dodge Charger Automatic Transmission Oil Pressure Sensors

Dodge Charger Automatic transmission oil pressure sensors

Starting at $135.95, AutoBuffy stocks 2 automatic transmission oil pressure sensors from Standard Ignition and GPD. This sensor monitors hydraulic pressure inside your Dodge Charger's transmission and sends real-time data to the TCM so it can control shift timing and clutch engagement. When it fails, the transmission loses accurate pressure feedback, triggering harsh shifts, limp mode, or transmission damage if ignored.

Signs your Dodge Charger needs a new automatic transmission oil pressure sensor

  • Transmission warning light or check engine light illuminated with a pressure-related fault code (commonly P0840, P0842, P0845, or similar)
  • Harsh, jerky, or delayed gear shifts that feel noticeably different from normal driving
  • Transmission enters limp mode, locking into a single gear and limiting vehicle speed
  • Erratic or hunting shifts where the transmission cycles repeatedly between gears without cause
  • Transmission slipping under load even though fluid level and condition are normal
  • No-start or stall condition in vehicles that use transmission pressure data to control torque converter lockup at idle

Which automatic transmission oil pressure sensor should you buy for your Dodge Charger?

The right sensor depends on which pressure circuit it monitors — line pressure, clutch pack pressure, or a secondary control circuit — because many Dodge Charger transmissions use more than one sensor in different locations. OEM-spec sensors are the safest choice for emissions-tested or warranty-tracked vehicles, while quality aftermarket units offer savings without sacrificing accuracy on older or high-mileage applications.

Replacing the automatic transmission oil pressure sensor on a Dodge Charger

Moderate⏱ 30 minutes to 2 hours depending on sensor locationOBD-II scan tool (to read and clear codes)Socket set and ratchetSensor socket or open-end wrench sized to the sensor hexDrain pan and transmission fluid (if pan removal is required)Electrical contact cleaner and dielectric grease

Externally mounted sensors on the Dodge Charger's transmission case are straightforward — disconnect the harness, unthread the sensor, install the new one, and reconnect. Sensors requiring pan removal add a fluid drain and refill step, so have the correct transmission fluid type and quantity on hand before starting. After installation, clear fault codes with a scan tool, test drive through all gear ranges, and confirm no codes return.

Frequently asked questions

How much does it cost to replace automatic transmission oil pressure sensors on a Dodge Charger?
Parts start at $135.95 at AutoBuffy. The sensor itself is relatively inexpensive, but total repair cost depends on location — a sensor on the external transmission case costs far less in labor than one requiring pan removal or valve body access. Expect shop labor to add one to two hours on most Dodge Charger applications.
Can I drive my Dodge Charger with a bad transmission oil pressure sensor?
You can drive short distances if the transmission is still shifting, but it is not advisable. A faulty sensor can cause the TCM to command incorrect line pressure, accelerating clutch pack and band wear. If the Dodge Charger has entered limp mode, driving farther than necessary risks internal transmission damage that far exceeds the sensor replacement cost.
Will replacing the sensor fix limp mode on my Dodge Charger?
It will if a pressure sensor fault code is the root cause. Confirm with a scan tool that an active pressure sensor code exists before replacing the part. Limp mode can also be triggered by low fluid, a failing solenoid, or internal mechanical faults, so clear codes after the repair and verify they do not return.
Do I need to drop the transmission pan to replace the sensor on my Dodge Charger?
Not always. Many Dodge Charger transmissions mount at least one oil pressure sensor externally on the case or valve body housing, accessible without removing the pan. However, some secondary or clutch-circuit sensors are internal. Check your specific sensor location before starting — if the sensor requires pan or valve body removal, plan for a fluid and filter change at the same time.
How do I know which transmission oil pressure sensor is bad on my Dodge Charger?
Read the fault code with a scan tool — codes like P0840–P0843 indicate the A-pressure circuit, while P0845–P0848 point to the B-circuit, and additional codes reference further circuits. Cross-reference the code to the physical sensor location in a wiring diagram for your Dodge Charger so you replace the correct unit rather than guessing.
Does the transmission oil pressure sensor need to be programmed after installation on a Dodge Charger?
In most cases, no programming is required — the replacement sensor is a passive pressure-to-voltage transducer and the TCM reads it immediately. However, on some newer Dodge Charger platforms with adaptive transmission learning, clearing the fault codes and performing a transmission adaptation reset via a scan tool is recommended to allow the TCM to relearn shift parameters correctly.
