The P1745 - Line Pressure Too High For Too Long code on your 2008 Dodge Magnum SE with the 42RLE transmission means that the transmission control module (TCM) has detected excessively high line pressure for an extended period. This can lead to harsh shifting, slipping, or even transmission overheating.
Possible Causes of P1745:
-
Faulty Line Pressure Solenoid
- The solenoid that regulates transmission fluid pressure may be stuck or malfunctioning.
-
Defective Pressure Sensor
- A faulty transmission pressure sensor could be sending incorrect readings to the TCM, leading to incorrect pressure adjustments.
-
Blocked or Dirty Transmission Valve Body
- Debris or sludge in the valve body can cause pressure regulation problems.
-
Transmission Fluid Issues
- Low, dirty, or overfilled transmission fluid can cause pressure irregularities.
-
Wiring or Connector Problem
- A short or broken wire to the line pressure solenoid can cause it to remain stuck at high pressure.
-
Internal Transmission Damage
- Worn clutches, seals, or a failing pump can cause high pressure as the transmission tries to compensate.
Troubleshooting & Fixes:
1. Check the Transmission Fluid:
- Ensure the fluid is at the proper level.
- If the fluid is dark or burnt, perform a fluid and filter change.
2. Inspect the Wiring & Connectors:
- Look for damaged, frayed, or corroded wires going to the line pressure solenoid and pressure sensor.
3. Test the Line Pressure Solenoid:
- Using a scan tool, monitor transmission line pressure.
- If pressure remains excessively high, the solenoid may need replacement.
4. Inspect the Valve Body:
- If fluid and solenoid checks don’t resolve the issue, the valve body may need cleaning or replacement.
5. Perform a Transmission Relearn:
- Some high-pressure issues can be corrected by performing a quick relearn procedure with a diagnostic scanner.
6. Check for Internal Damage:
- If the problem persists after solenoid and fluid checks, internal transmission damage may be present, requiring a transmission rebuild or replacement.
Final Recommendation:
If you’re experiencing harsh shifting or transmission overheating, address the issue as soon as possible to prevent further damage. Start with fluid and solenoid checks, and if the problem persists, a professional transmission diagnosis may be needed.
