8. Turn the pump "OFF."
9. Disconnect the CLEAR suction line from the reservoir at the

cover plate. Disconnect the CLEAR return line at the cover
plate, and place it in a drain pan.

10.Turn the pump "ON" for 30 seconds to purge flushing

solution from the cooler(s) and lines. Turn the pump "OFF."

11.Place the CLEAR suction line into a one quart container of

DIAMOND ATF SP III or equivalent transmission fluid.

12.Turn the pump "ON" until all transmission fluid is removed

from the one quart container and lines. This purges any
residual cleaning solvent from the transmission cooler(s)
and lines. Turn the pump "OFF."

13.Disconnect the alligator clips from the battery. Reconnect

the flusher lines to the cover plate, and remove the flushing
adapters from the cooler lines. Reconnect the cooler lines.

OIL COOLER FLOW CHECK

M1231104900145

After the new or repaired transmission has been installed, fill to
the proper level with DIAMOND ATF SP III or equivalent trans-
mission fluid. The flow should be checked using the following
procedure:

CAUTION

With the fluid set at the proper level, transmission fluid
collection should not exceed one quart or internal damage
to the transmission may occur.
1. Disconnect the OUTLET line (from cooler) at the

transmission and place a collecting container under the
disconnected line.

2. Run the engine at curb idle speed with the shift selector in

neutral.

3. If transmission fluid flow is intermittent or it takes more than

20 seconds to collect one quart of transmission fluid, replace
the cooler.

4. If flow is within acceptable limits, reconnect the cooler line.

Then fill the transmission to the proper level, using
DIAMOND ATF SP III or equivalent transmission fluid.

1. Set the selector lever to the "N" position.
2. Loosen the control cable to manual control lever coupling

nut to free the cable and lever.

3. Set the manual control lever to the neutral position.
4. Loosen the transmission range switch body mounting bolts

and turn the transmission range switch body so the hole in
the end of the manual control lever and the hole (cross
section A

− A in the figure on the left) in the flange of the

transmission range switch body flange are aligned.
NOTE: The transmission range switch body can be aligned
by inserting a 5-mm diameter steel bar into the end hole of
the manual control lever and the flange hole of the transmis-
sion range switch body.

5. Tighten the transmission range switch mounting bolts to the

specified torque. Be careful at this time that the switch body
does not move.

Tightening torque: 11

± 1 N⋅m (98 ± 8 in-lb)

6. Gently pull the transmission control cable in the direction of

the arrow (B), until the cable is taut. Tighten the adjusting
nut.

Tightening torque: 23

± 4 N⋅m (17 ± 3 ft-lb)

7. Check that the selector lever is in the "N" position.
