J21867
to the main line pressure fining located
at the front of the transmission below the
transmission pump. Fig. 13

2.
Run the engine until transmission reaches
normal operating temperature (coolant fans
begin to cycle -A/C off).
3. Raise the vehicle on a hoist which will allow the
rear wheels to turn freely.
4.
Disconnect the vacuum hose from the vacuum
modulator.
5. Start the engine, place the transmission sector
lever in DRIVE, and run the rear wheels until
2,500 RPM is reached with the transmission
shifted into third gear.
6. Read transmission fluid pressure; the pressure
should be 8 Bar ± .2 (113
PSI
± 3) when the
transmission fluid temperature is 80°C.
(176°F.).
7. Adjust the fluid pressure by unlocking the
retaining clip and rotating the vacuum
modulator in its housing. Fig. 14

Notice:
Turning the modulator clockwise will increase the
fluid pressure. One notch of movement will change
the pressure approximately 0.1 Bar (1.5 PSI).
8. Install the modulator retaining clip, refit the
modulator vacuum hose, and remove the fluid
pressure gauge and install
plug.
9. Lower the vehicle, check and adjust
transmission fluid level.
