Thanks in advance.
the 722 tranny manual reads the following:
"HARSH ENGAGEMENT WHEN SHIFTING GEARS:

equipped with diesel engines, check vacuum control valve. Coolant

Replace radiator. If necessary, replace all friction linings and/or
HARSH ENGAGEMENT WHEN SELECTING "D" OR "R":
Idle speed too high. Check pressure receiving (pick-up)
piston in valve body for ease of operation and correct installation.
Replace valve body (if necessary).
NOTE: Pressure pick-up requires a running period of approximately
2 seconds. Harsh engagement may occur during repeated shifts
between "N" and "D". If harshness takes place within 2
seconds, condition is considered normal.
