If the transmission happens to shift early after the coarse adjustment, grab the cable adjuster so it doesn’t move, and push the release button, and then move the cable back toward the bracket a few clicks. After you get the transmission to shift at the right speed for the 1-2 and 2-3 shifts, you are ready to verify the transmission has a full throttle 2-1 down shift.
Watch out when swapping stator shafts from one pump cover to another on 700-R4/4L60-E transmissions. We have all been there before. You have a unit with a good pump cover and a damaged stator shaft, and in your pile of parts there is a good stator shaft in a damaged pump cover. All you need to do is press the good stator shaft into the good pump cover and you will have what you need to get this car down the road today. Sounds simple, but how often are things that simple in this business?
