LUBRICATION
SERVICE INTERVALS
Transmission
Check fluid level and condition of fluid at each engine oil
change. Under normal, light duty operating conditions, change fluid,
replace filter and adjust bands every 2 yrs. or 25,000 miles. Under
heavy duty service, change fluid, replace filter and adjust bands
every 12 months or 12,500 miles.
Transfer Case
Check transfer case fluid every 12,000 miles and replace
fluid every 30,000 miles.
CHECKING FLUID LEVEL
Transmission
Park vehicle on a level surface and apply parking brake.
With engine idling at normal operating temperature, move transmission
selector lever through all gears, ending in "N" ("P" for AW-4
transmission). Check fluid level. Fluid level should be between
"FULL" and "ADD ONE PINT" mark on dipstick. Add fluid as needed. DO
NOT overfill.
Transfer Case
Remove fill plug. Check oil level. If level is not up to
fill plug opening, add lubricant until it is.
RECOMMENDED FLUID
Both transmissions and transfer cases use DEXRON-II ATF.
FLUID CAPACITY
NOTE: Transmission and converter capacities are approximate. Fluid
level should always be determined by reading on dipstick,
rather than amount of fluid added.
