Check transmission fluid level when performing other
underhood services. Fluid change service interval information is not
available from manufacturer.
Transfer Case
Check transfer case fluid level when performing other
underhood services. On Dakota and Light-Duty Pickup, change transfer
case fluid at 37,500 miles or 30 months. On Medium-Duty and Heavy-Duty
Pickup, change transfer case fluid at 36,000 miles or 36 months.
CHECKING FLUID LEVEL
