I uninstalled many of the kit options today and finally have a transmission that shifts quite well. Left in place was the purple K1 accumulator spring, the short dark blue K2 accumulator spring and the "plain" B1 accumulator control valve spring.

Here are some lessons learned:

The instructions furnished with the kit (or should I say the instructions that should have been furnished with the kit) are excellent in some ways and lacking in others.

There are transmissions that do not fit squarely into either the early or late model definitions.

When separating the upper and lower valve body assemblies, it is important that the separator plate not be allowed to slide. Inserting a couple of the valve body bolts "backwards" will keep the plate in place. After removing the two screws that hold the valve body together, flip the body upside down (hold together tightly) and then lift the lower portion (which is now on top)off of the upper half (now on the bottom), leaving the two through bolts in place (heads down) so that the separator plate cannot slip from its original position.

Work in a clean, well lit and uncluttered area.

Label all springs removed from the valve body. You might need to put them back where they came from if the kit springs don't work as anticipated.

The small valve body screws are quite tight and it is easy the strip the slots with an ordinary, tapered screw driver blade. Hollow ground screwdrivers or bits work much better. (A gunsmith screwdriver kit is perfect.)

Consider installing only the kit components that address the problems that you are experiencing. Attempting to fix problems that you don't have may result in new problems.

The drawing in post #11 here http://www.peachparts.com/shopforum/showthread.php?p=1789037#post1789037 is invaluable if you need to (or inadvertantly ) remove the separator plate from the upper valve body. Expect several on the components to stick to the plate and/or "spring" free. Items 4,5 8 & 9 deserve particular attention. Except for item 4, which is a check ball seated on a spring, the remainder of the check balls are deeply recessed and should not move as long as the upper valve body remains flat.

Torque the 15 valve body bolts to 8 Nm.
