Well, Trans is back in car, and so far so good. Shifts a little softer than I hadf thought it would to be honest. I had picked up the "shift improvement kit", did all the necessary stuff:
Drilled a .073 hole in the pressure reg valve in oil pump
Replaced outer press reg spring
Replaced the converter control switch valve, and new springs
Replaced forward clutch accumulator spring
Replaced 4-3 return spring
Ground 1/8" off piston retainer seat
Replaced servo cushion spring
Installed steel orfice plug in 3-4 accumulator bore
Changed out springs in the 1-2 accumulator
Drilled out separator plate in all the places mentioned (8 places in all)
Left out the #6 check valve in valve body
Turned adjustment screw on force motor 1/4 turn
Also, I DID leave out the load release springs as well. Some say leave em in, most say leave em out. I left them out.

ON light throttle, shifts are hardly even noticeable. I mean, you know they take place, but very wimpy like if you ask me (basically shifts just like a stock trans does) However, you get in the throttle some, around half throttle, and shifts clean up some and are much more firm. We haven't done any full throttle blasts yet (been raining here) so, guess we will see.
Trans works, and all of that, and Im happy with that of course, but thought with all the "improvements" in trying to firm up the shifts, it would've shifted much more firm and crisp.

Any idea's, or is what I am explaining pretty typical of the 4l60e?
