My 2004 GC Special Edition 123k just started acting up. Randomly the check engine light comes on and the trans doesn't downshift to 1st at a stop. Accelerates slowly from 2nd and doesn't shift to 3rd until 40mph. Just as randomly, the engine light goes out and the trans operates normally. Superchip DTC showed P1764 Governor Pressure Sensor Low. Good thing I photographed the screenshot because I can't get it to read a DTC when the engine light comes on and it won't clear the check engine light either. I've kept her regularly maintained and I just hope I can make it back to my trusted mechanic (125 miles away) before she balks on me.
Sooo. I've seen comments on P1762 and P1763 codes but what about P1764. What exactly do I need to get to fix her? It saves time and money when I can take the car and the part to my mechanic. He's a doll!
