ON-VEHICLE MAINTENANCE
A/T FLUID
Checking the A/T Fluid (ATF)INFOID:0000000005148722
CAUTION:
If using the vehicle for towing, the A/T fluid must be replaced as specified. Refer to MA-9, "
Introduc-
tion of Periodic Maintenance".
1. Before driving, the A/T fluid level can be checked at A/T fluid temperatures of 30 ° to 50° C (86° to 122° F) using the “COLD”
range on the A/T fluid level gauge as follows:
a. Park the vehicle on a level surface and set the parking brake.
b. Start the engine and move the selector lever through each gear position. Shift the selector lever into the “P” position.
c. Check the A/T fluid level with the engine idling.
d. Remove the A/T fluid level gauge and wipe it clean with a lint- free paper.
CAUTION:
When wiping the A/T fluid from the A/ T fluid level gauge,
always use a lint-free paper, not a cloth.
e. Re-insert the A/T fluid level gauge into the A/T fluid charging pipe until the cap contacts the t op of the A/T fluid charging pipe
as shown.
CAUTION:
To check A/T fluid level, insert th e A/T fluid level gauge until
the cap contacts the top of the A/T fluid charging pipe, with
the gauge reversed from th e normal inserted position.
f. Remove the A/T fluid level gauge and note the A/T fluid level. If the A/T fluid level is at low si de of range, add A/T fluid to the
transmission through the A/T fluid charging pipe.
CAUTION:
Do not overfill the transmission with A/T fluid.
g. Install the A/T fluid level gauge and the A/T fluid level gauge bolt.
2. Warm up the engine and transmission.
3. Check for any A/T fluid leaks.
4. Drive the vehicle to increase the A/T fluid temperature to 80 ° C (176 ° F).
