Need Advice on 4R75W broken E clip, but no pieces in the valve body
Hey Everyone
Ive got the same problem as others with the OD going out, works just fine with OD off button etc.....
Pulled the valve body expecting to see the large C clip in the servo shaft broken like most everyone else, but it was not........
The small E clip (3/8") that holds the servo shaft to the plunger was broken. The biggest piece was on top of the valve body and the small broken piece was down in the pan.....nothing stuck in the OD valve like described by others..
Would the broken E clip that holds the shaft and plunger together cause a loss of the overdrive?????? If that clip is broken the shaft and plunger move separately it appears and not together as they are supposed to.......if i push up on the shaft I can see the servo band (thru the peek hole) move up so I know the shaft is connected to the servo band......With the E clip broken off, did i lose OD because the servo is not able to push the OD band upwards because the plunger and the shaft are not tied together???? Will putting a new E clip likely fix the OD problem......???? Need some expert advice......thanks

Did you check the OD servo regulator valve in the valve body? I bet a piece of the clip has jammed the valve. You have to remove the separator plate off the valve body to see this valve. even the smallest piece can jam the valve and cause it to stick in the exhaust position.

Thanks Mity Merc
I did remove the entire valve, but did not notice anything. Gonna put it back together again soon..... Just wondering what effect that broken E clip had on the servo and if that might be the problem....Im just not sure exactly how the servo works in terms of the shaft and servo being together with that E clip? When that clip broke, did the OD quit working or is it not a factor in losing the OD?
