While the valve body is out, check the TV plunger to see if it’s stuck in, what the Bowden cable pushes on. A little dirt in, on the governor screen is normal, you don’t what then plugged.

If the plunger is not stuck, remove the governor and check for a stuck valve and or damage to the governor body = a bad case. Can you post a picture of the pieces in the pan


The vacuum modulator on a 722.3,4 and 5 transmissions does not control, command the transmission to shift.

Here is a picture of the two pieces found in the pan (dimensions in inches):

After removing front and rear valve bodies, checking governor valve action, kick-down solenoid, TV (cable actuated) valve on valve body, action of 1-2 shift command valve and a few others, all I found was some dirt in one of the little screens in the rear valve body (as suggested by David S Poole). Everything seemed fine otherwise. I put it all back together with new gaskets and now transmission works fine. I guess it must have been the small amount of dirt clogging the thimble-shaped screen. This has certainly taught me to be more dilligent about trans fluid changes.

Thankyou all for the helpful suggestions!

Where exactly is this "thimble shaped" screen ?

Thanks,

The debris in the picture look like pieces of the valve body separator plate gasket. It's a thick paper like gasket that sometimes tears/breaks apart during removal........

The thimble screens are located on the oil-separator plate.
