Checking A/T Fluid

INFOID:0000000001328919

Warm up engine.

Check for A/T fluid leakage.

Loosen the level gauge bolt.

Before driving, A/T fluid level can be checked at A/T fluid tem-
peratures of 30 to 50

C (86 to 122

F) using “COLD” range on A/

T fluid level gauge as follows.

Park vehicle on level surface and set parking brake.

Start engine and move selector lever through each gear posi-
tion. Leave selector lever in “P” position.

Check A/T fluid level with engine idling.

Remove A/T fluid level gauge and wipe clean with lint-free
paper.

CAUTION:

When wiping away the A/T fluid level gauge, always use
lint-free paper, not a cloth one.

Re-insert A/T fluid level gauge into A/T fluid charging pipe as far as it will go.

CAUTION:

To check A/T fluid level, insert the A/T fluid level gauge until the cap contacts the end of the A/T
fluid charging pipe, with the A/T fluid level gauge reversed from the normal attachment conditions.

Remove A/T fluid level gauge and note reading. If reading is at low side of range, add ATF to the A/T fluid
charging pipe.

CAUTION:

Do not overfill.

Drive vehicle for approximately 5 minutes in urban areas.

Make the A/T fluid temperature approximately 65

C (149

F).

• If ATF is very dark or smells burned, check operation of A/T.

Flush cooling system after repair of A/T.

• If ATF contains frictional material (clutches, bands, etc.),

replace radiator and flush cooler line using cleaning solvent
and compressed air after repair of A/T. Refer to

VQ35DE) or

(for VK45DE) and

Install the removed A/T fluid level gauge in the A/T fluid charging
