2-27
Push the overdrive switch to the OFF position at speeds below 65
MPH (105km/h) to increase engine braking action when traveling
downgrade.
If the automatic transmission fluid temperature is too low, the
transmission may not initially make automatic shift to the 4th, 5th and
6th gear. This condition is normal and will be resolved as the fluid
temperature rises.
2: SECOND
Select the “2” position at speeds below 25 MPH (40km/h) when
traveling down a moderate grade. The braking action of the engine will
hold your speed down. Continued use of the wheel brakes will not be
required. Use of the exhaust brake will also aid downhill braking.
Return the selector to the “D” position for normal driving.
1: FIRST
Use the “1” position for maximum engine braking on steep downhill
grades.
Return the selector to the “D” position for normal driving.
DRIVING TIPS
Before descending a long, steep grade, reduce speed and turn off the
overdrive switch. This is the safe way to control your truck’s speed.
Avoid continuous or frequent use of the wheel brakes over a long
p e r i o d o f t i m e . D o i n g s o w i l l l e a d t o b r a k e o v e r h e a t i n g a n d
dangerously reduced braking efficiency.
NOTICE:
* Never move the selector from the “P” or “N” position to one of
the drive positions with the engine running at a high speed.
Damage to the automatic transmission will result.
* Never move the selector into the “P” position when the vehicle is
in motion. Damage to the automatic transmission will result.
* Do not operate the automatic transmission at or near stall
condition for more than five seconds.
Stall condition is when the transmission is in one of the driving
ranges, the engine is running at high speed, but the drive wheels
are unable to move. This condition might occur if the vehicle is
stuck in deep sand or is pushing against a fixed barrier.
