98 Jeep transmission codes

I have a 98 Jeep Grand Cherokee with 5.2 and quadratrac trans.The codes are;
P1762 gov pressure offset voltage high/low

P1757 gov pressure above 3psi with 0 mph

Tranny stays in first gear.Is this simple or involving teardown??

This is a fairly common failure, replace both the governor pressure solenoid and the governor pressure sensor.

Easy to access by just removing the pan.
