Transmission problem

do you have the hyrdaulic version or electrictronnically controlled version?
im guessing you have the 47RE
and have you verified the correct transmission fluid level?
low fluid level can cause hard engagements.
-the kickdown valve is what performs your 3-2 downshift
-The limit valve determines maximum speed at which a 3-2 part throttle kickdown can be made. On transmissions without a limit valve, maximum speed for a 3-2 kickdown is at detent position.
-The 2-3 shuttle valve has two functions. First is fast front band release and smooth engagement during lift-foot 2-3 upshifts. The second is to regulate front clutch and band application during 3-2 downshifts.
