I had my car checked and the dignostics said I needed a new pressure switch in my transmission, and we changed that but it still is not going into gear and the engine makes a loud revving sound, like it is getting stuck from gear to gear, or that it skips a gear. We checked the fluid and the pan was good- no metal shavings..and now it continues to do the same thing but is driveable, a new code P1757 AND P1762 came up- can anyone help me who knows what those codes mean?
P1757 1T CCM 1996-2003 Cherokee, Grand Cherokee A/T Governor Pressure Above 3 PSI In Gear At 0 MPH Conditions: Engine started; vehicle driven to a speed over 30 mph, and the PCM detected the Governor Pressure Sensor was more than 3 psi with the requested pressure at 0 psi (95% duty cycle command) for 2.65 seconds. The fault must occur twice on one trip to set the code. Possible Causes: Check for the presence of other A/T related trouble codes Governor pressure Sensor is damaged or has failed Governor pressure Sensor VREF (5v) circuit is open or shorted Transmission valve body is leaking, damaged or has failed PCM has failed P1762 1T CCM 1996-2003 Cherokee, Grand Cherokee A/T Governor Pressure Sensor Offset Volts Too High/Low Conditions: Key on or engine running. Gear selector in Park or Neutral. PCM detected an out-of-range Governor Pressure Sensor signal for 1.3 seconds. The fault must occur 3 times on one trip to set a code. Possible Causes: Governor pressure Sensor VREF (5v) circuit is open Governor pressure Sensor ground circuit is open P/N switch is damaged or has failed (not operating properly) Transmission fluid has excessive debris or it is contaminated PCM has failed
But, I would leave this up to a transmission place. It may need a special type of calibration tool for the new sensor.5,158 views
