Grand Cherokee 2WD L6-242 4.0L VIN S MFI (1993)
Fig. 138 Line Pressure Adjustment
Measure distance from the valve body to the inner edge of the adjusting screw with an accurate steel scale (Fig. 138).
Distance should be 33.4 mm (1-5/16 inch).
If adjustment is required, turn the adjusting screw in, or out, to obtain required distance setting.
The 33.4 mm (1-5/16 inch) setting is an approximate setting. Because of manufacturing tolerances, it may be necessary to vary from this dimension to
obtain desired pressure.
One complete turn of the adjusting screw changes line pressure approximately 1-2/3 psi (9 kpa:). Turning the adjusting screw counterclockwise
increases pressure while turning the screw clockwise decreases pressure.
Fig. 139 Throttle Pressure Adjustment
Throttle Pressure Adjustment
Insert Gauge C-3763 between the throttle lever cam and the kickdown valve stem (Fig. 139).
Push the gauge tool inward to compress the kick-down valve against the spring and bottom the throttle valve.
Maintain pressure against kickdown valve spring. Turn throttle lever stop screw until the screw head touches throttle lever tang and the throttle lever
cam touches gauge tool.
The kickdown valve spring must be fully compressed and the kickdown valve completely bottomed to obtain correct adjustment.
