Home x-old ACPN Tech Tip: Dodge Has A P2767 Code With Transmission In Limp In...

Print Print Email Email

Applies To:
2006 300 3.5L
2006-’07 300 5.7L
2006-’07 Charger 3.5L
2006-’08 Charger 5.7L
2009 Grand Cherokee 3.7L
2006 Magnum 5.7L

Customer Concern:
P2767 trouble code (Torque Conv Clutch Press Ctrl Solenoid Ctrl Circ Range/Perf) is setting. Transmission is in limp in mode.

Potential Causes:
Lead Frame or Transmission Wiring

Tests/Procedures:
1. Check the wiring between the transmission and the transmission control module. Make sure the #2 signal wire is not open, shorted to ground, or shorted to any other circuit.

2. If the wiring checks OK, raise all four wheels off the ground, start the vehicle and place the shifter in drive. While lab scope testing the #2 signal wire, obtain second gear. When the transmission is in second gear, there should be a 5-volt square wave pattern being produced by the #2 sensor. If not, replace the sensor.

Tech Tips:
The speed sensors are sold as a complete assembly, which may be called the “lead frame” or ­possibly the “electrohydraulic control unit.”
