Testing and Adjusting
1. Make sure that the transmission control lever is in
the park brake position.
2. Warm the oil to a minimum temperature of 60°C
(140°F).
NOTE: Third gear that uses clutches E and G is shown
in the following test:
3. Connect one end of tooling (A) to the test port on
valve E. Connect one end of a second tooling (A) to
the test port on valve G.
4. Operate the transmission in third gear at high idle.
5. Observe the pressure that is being delivered to
transmission clutches E and G. Use the table above
(or a copy of that table) to write down the
measurement.
6. Stop the engine.
7. Repeat steps 3 through 6 for the remaining reverse
gears and forward gears. Use the table in order to
determined the combination of modulating valves
that are being engaged for each gear.
8. Compare the pressure measurements from all of
the transmission clutches. The pressure
measurement should be within 2100 ± 35 kPa (305
± 5 psi).
9. Remove tooling (A).
10. Stop the engine.
11. If the pressure is not within the specified limits,
check the pressure that is being delivered by the
