46RE trouble, again...... - 03/21/16 12:31 PM

So after I took care of the broken snap rings and the governor solenoid kit for the P1757 code, the Durango drove great. Friday I noticed that when I came to a stop, it didn't downshift to 1st. You can manually shift into 1st or bump it to neutral for a second and all is well again. This is kind of intermittent- it might do it one time or it might do it 3or 4 times in a row. No codes...

Suggestions?

Watch the gov sensor actual and desired pressures, if they are not the same switch em both out. Get the big BW solonoid. There is not a governor switch just a pressure/temperature sensor and variable solonoid.

That should have fixed it, perhaps a spec of dirt got into one somehow, it wouldn't take much.

A stuck shift valve in the VB will act just like a governor problem....no downshift when rolling to a stop.

Planning on dropping the valve body and cleaning it when I have a little time.
Thanks, John.

What year truck is it?
And what is the part number of the transducer you installed - you show two part numbers.

It's a 2000. I didn't even notice the parts list showed 2 part #s.

As of right now, it's been shifting normally ever since I asked. Probably was a speck of dirt that passed on through as Dave said.

I'll keep my fingers crossed anyway.
