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.
