This could also be the reason that I can not get any 3rd gear action in the "D" gear selector position (not overdrive). The transmission gets from 1-2 no problem but holds 2nd no matter what I try and "OD" just acts like neutral.
Basically it is acting like the opposite of what it should.
Forward sprag in backwards will provide no movement in OD... shift to "D" will apply over run clutch, vehicle will then move from a full stop
Clean the v-body. DO not remove all valves at once. Do not flip over the aluminum sleeves , watch how they come out and where pins install. Some folks re-install incorrectly.
ALL shift valves must move fully for the trans to operate - shift correctly
