Automatic Transmission: Maintenance Nissan Rogue I

CHECKING CVT FLUID

The fluid level should be checked with the fluid warmed up to 50 to 80°C (122 to 176°F). The fluid level check procedure is as follows

Scheme 93

Scheme 94

Scheme 95

Scheme 96

1. Check for fluid leakage.
2. With the engine warmed up, drive the vehicle in an urban area. When ambient temperature is 20°C (68°F), it takes about 10 minutes for the CVT fluid to warm up to 50 to 80°C (122 to 176°F).
3. Park the vehicle on a level surface.
4. Apply parking brake firmly.
5. With engine at idle, while depressing brake pedal, move shift selector throughout the entire shift range. see scheme 64: Checking Fluid Leakage
6. Pull out the CVT fluid level gauge from the CVT fluid charging pipe after pressing the tab on the CVT fluid level gauge to release the lock. see scheme 65: Identifying CVT Fluid Level Gauge And CVT Fluid Charging Pipe
7. Wipe fluid off the CVT fluid level gauge. Insert the CVT fluid level gauge rotating 180° from the originally installed position, then securely push the CVT fluid level gauge until it meets the top end of the CVT fluid charging pipe. CAUTION: When wiping away the CVT fluid level gauge, always use lint-free paper, not a cloth rag. see scheme 66: Identifying CVT Fluid Level Gauge And CVT Fluid Charging Pipe
8. Place the selector lever in "P" or "N" and check that the fluid level is within the specified range. CAUTION: When reinstalling CVT fluid level gauge, insert it into the CVT fluid charging pipe and rotate it to the original installation position until securely locked.

Check CVT fluid condition.

Scheme 97

1. If CVT fluid is very dark or smells burned, check operation of CVT. Flush cooling system after repair of CVT.
2. If CVT fluid contains frictional material (clutches, brakes, etc.), replace radiator and flush cooler line using cleaning solvent and compressed air after repair of CVT. Refer to " «FLUID COOLER: EXPLODED VIEW»(ref-295118-S09179841802008081400000) " (with fluid cooler), " «CLEANING»(ref-295118-S00853197892008081400000) ". CVT FLUID CONDITION REFERENCE CHART Fluid status Conceivable cause Required operation Varnished (viscous varnish state) CVT fluid become degraded due to high temperatures. Replace the CVT fluid and check the CVT main unit and the vehicle for malfunctions (wire harnesses, cooler pipes, etc.) Milky white or cloudy Water in the fluid Replace the CVT fluid and check for places where water is getting in. Large amount of metal powder mixed in Unusual wear of sliding parts within CVT Replace the CVT fluid and check for improper operation of the CVT. (Scheme 94): Checking CVT Fluid Condition
