I am in the process of rebuilding the 727 transmission from my 91 GW. After taking the valve body apart, it seems that I have an extra check ball. Here is some information:
As Found:
Check balls in the valve body = 8 (7 small, and 1 large)
Check balls in the transfer plate = 1 (small)
Per Service Manual:
Check balls in the valve body = 7 (6 small, and 1 large)
Check balls in the transfer plate = 1 (small)
The extra check ball is the 4th one down from the top of this picture.
And here is a picture of the separator plate lined up on the valve body. At all places where there is suppose a check ball, there are round holes on the separator plate, so that the ball can actually check. At the location of the extra check ball, there is a rectangular opening.
The extra check ball also did not move freely. I needed to use a screwdriver to pry out this check ball.
So, is this check ball needed? Can I just leave it out in the rebuild?
