My 99 Ram 1500 is throwing a P1757 DODGE Code - Governor Pressure Above 3 psi at 0 MPH and not shifting into 1st.. when it is cold is shifts fine but as soon as it warms it is stuck in high gear. I replaced both governor sensor and solenoid and had no change what so ever. Anybody know what solenoid I shoud replace next ?

 

Did you clear the code?
Also just seen the multiple post.

yes I cleared the code. It is throwing a P1756 and P1757 now and I do think it is a solenoid problem in the way that it shifts fine when cold. As soon as it gets down the road a ways and warms then it fails.I can shift it into 2nd manually, but not into 1st. Now remember, I replaced both governor sensor and solenoid with no change what so ever.

 

Then electronics aren't the problem.... Something else is going on.

 

P1756 Governor Pressure Not Equal to Target @ 15-20 PSI

P1757 Governor Pressure Above 3 PSI In Gear @ 0 MPH

How did you clear the codes? If you have a scanner that can read live data you can see what you are getting from the governor sensor. You can also do a pressure test with a gauge. You should have about 1 psi per 1 mph.
