PERIODIC SERVICE RECOMMENDATIONS
TOWING
If the transmission, drive line or axle do not have a mal-
function, the vehicle may be towed in neutral at speeds up
to
45
mph. The distance should not exceed 50 miles.
For higher speeds or extended distances, it is recom-
mended that the propeller shaft be disconnected or the
rear wheels be off the ground.
TRANSMISSION FLUID
Transmission fluid level should be checked (with trans-
mission hot) every time engine oil level is checked or every
6000 miles when engine oil is changed.
CAUTION: Since the Turbo Hydra-Matic
(M-40) transmission is very sensitive to oil
/eve/, special precautions should be taken when
checking the oil /eve/, to ensure against an over-
fill
(see Checking Procedure).
Transmission fluid and filter assembly should be changed
every 24 months or 24,000 miles, whichever occurs first.
Refill with DEXRON or equivalent automatic transmis-
sion fluid. Under heavy-duty operating conditions or
excessive stop-and-go driving, replace the fluid and filter
assembly at 12,000 mile intervals.
