CHECKING FLUID LEVEL
| WARNING | On 4WD models, ensure transfer case is in any gear range EXCEPT Neutral before checking transmission fluid level. |
Note. On AX4S transaxle, fluid level should be checked when fluid is cold only for purposes of ensuring fluid level is above DO NOT DRIVE mark. Once fluid is above DO NOT DRIVE mark, follow normal checking procedure.
Note. F350 commercial chassis may have a parking brake assembly mounted on rear of transmission. Parking brake assembly contains a separate reservoir. Fluid level must be checked separately from transmission. See PARKING BRAKE ASSEMBLY (F350) .
- Transmission or transaxle must be at normal operating temperature with vehicle on level ground. Apply parking brake, and run engine at curb idle. Shift gear selector lever through all positions, ending in Park.
- Fluid level should be in crosshatch area on dipstick if checked at operating temperature. If transmission is at room temperature, fluid level should be between 2 dimples on bottom of dipstick.
- DO NOT overfill. Check condition of fluid for contamination and burned smell. Fully reseat dipstick.
DRAINING & REFILLING
| WARNING | On vehicles with electrical air suspension, power to air suspension system must be shut off prior to hoisting, jacking or towing an air suspension vehicle. On Pickup and Van, air suspension switch is located behind right kick panel area. On cars, air suspension switch is located in left side of trunk. Failure to do so can result in inflation or deflation of air springs, which may cause vehicle to shift during servicing. |
