12.1.1.4
Check the oil levels often. Oil seals are more likely to leak in extreme hot weather.
NOTE
If the temperature of the transmission fluid is above 270 degrees F (132 degrees C) the
CHECK TRANS light will come on.
12.1.1.5
If the TRANS TEMP gauge (Figure 12. 2. (2)) reads higher than 250 degrees F (121
degrees C), do the following:
a. Stop the launch vehicle and put the selector (Figure 12. 1 (1)) in the Neutral (N)
position while the engine is running to reduce the idle speed.
b. When the TRANS TEMP gauge (Figure 12. 2. (2)) reads in the normal range,
return the selector (Figure 12. 1 (1)) to its correct position and continue the
journey.
c.
If the TRANS TEMP gauge (Figure 12. 2. (2)) does not return to the normal
range, stop the truck and let the transmission cool.
d. When the TRANS TEMP gauge (Figure 12. 2. (2)) reads in normal range, start
engine, return rotary switch to its previous position and continue build.
12.1.2.1
Keep the operating temperature as low as possible.
12.1.2.2
Stop the launch in safe condition, turn the 4 position rotary switch to position 1 to
reduce the idle speed while engine is running. Let the engine idle for about two
minutes before shutting down. Idling will cool the engine faster than quick shutdown
and may prevent damage from remaining engine heat.
