FUNCTION/USE
Used when needed to limit automatic shift-
ing to a lower range because of road condi-
tions. Range 4, 3, 2, and 1 give increasing-
ly greater engine braking and hydraulic re-
tarder action. The lower the gear range, the
greater the braking, power, and retarding
effects. When conditions go back to normal,
select D position.
Used to restrict automatic shifting to the
2nd and 3rd gear range.
Used for driving through ice and snow, or for .
driving up steep grades. No automatic shift-
ing will occur in this position (unless engine
overspeed occurs).
Used to get greatest pulling power, engine
braking, and hydraulic retarder effect.
