Hello there,

I6, 42RE, NP242, F-DanaSuper30, R-Chrys/Dana35, (if you need any of that.)

I do not normally have issues with my transmission slipping, shuddering, making noise, etc, but it has happened twice now this year and its following by the code P1762 both times, as well as what sounds just like a power steering whine with the wheel turned all the way to lock. I know it is getting up there in mileage, but I'm shooting for 300,000 miles and the next car paid in cash. So I need this one to last a while longer! It says governor pressure sensor. Is this something easily replaced by the home mechanic? Is this caused by a plugged transmission filter or a defective sensor? Can it be checked or only replaced?
About 50,000 miles ago I changed the filter and gasket, and adjusted the bands via the internal and external screws at that time. Should I start there?

Thanks for your help!
Jordan

Hello,

It sounds like the transmission is coming apart and has clogged the filter, I would try servicing the unit to see if that helps so you can get a little more out of the car.

Here is a guide that will help you get the job done.
