This task covers:
Adjustment (page 2-808)
Pliers, round-nose, long
Transmission removed and mounted on test
Test stand, transmission
stand (page 2-633)
Transmission oil filter removed
Shift speeds are adjusted by changing positions of adjusting rings in control valve body and low
shift valve body assemblies.
Turning adjusting rings clockwise increases spring force on shift valves and raises transmission
shifting speed. Turning adjusting rings counterclockwise lowers shifting speed. Turning adjusting
ring one notch will change transmission speed approximately 40 RPM.
Using long round-nose pliers, push in
(2), (3), and (4)
and turn to adjust.
Low shift valve
Adjusting ring (6)
Using long round-nose pliers, push in and
turn to adjust.
The following chart shows output shaft RPM's at which various transmission shifts should occur.
On transmission test stand, check all shift speeds and compare with those shown on charts. Make
necessary adjustments to bring transmission shifts within the ranges shown on the chart on the
