Selector Slowdown Point
This figure shows the requirement of 3"-4" of leveling distance. If the car
slowdown and approach to the floor results in longer leveling than 3"-4",
car performance and fluid could degrade due to unnecessary fluid heating.

This figure shows the effect of using the P17/P18 Adjustments to control the leveling
distance. If the car slowdown and approach to the floor is comfortable as adjusted in
the valve but results in incorrect leveling distance (3"-4"), move the P17/P18
Selector Showdown Point properly.

This figure shows the effect of using the I-2/I-3 Valve Slowdown Screw Adjustments to control
the leveling distance. If the car showdown point P17/P18 is set but leveling is incorrect (not 3"-4"),
move the Valve Slowdown Screw.
• UP SLDN Screw: IN = Shorter leveling distance, increased leveling speed, softer feel to slowdown.
• DOWN SLDN Screw: OUT = Shorter leveling distance (with full load the distance is even shorter),
Set for at least 2" of leveling with a full load and increase P17
to help with full load down floor approach.
