Montero XLS 4WD V6-3.5L SOHC (2001)
Fluid - A/T: Testing and Inspection
A/T FLUID CHECK
1. Drive the vehicle until the fluid temperature rises to the normal temperature [70 - 90°C (158 - 194°F)].
2. Park the vehicle on a level surface.
3. Move the selector lever through all positions to fill the torque converter and the hydraulic circuits with fluid, and then move the selector lever to
the "N" position.
4. After wiping off any dirt around the dipstick, remove the dipstick and check the condition of the A/T fluid.
NOTE: If the A/T fluid smells as if it is burnt, it means that the A/T fluid has been contaminated by fine particles from the bushings and friction
materials, a transaxle overhaul and flashing the cooler line flushing may be necessary.
5. Check that the A/T fluid level is at the "HOT" mark on the dipstick. If the A/T fluid level is lower than this, pour in more DIAMOND ATF SP-II,
DIAMOND ATF SP-II M or equivalent until the level reaches the "HOT" mark.
NOTE: If the A/T fluid level is too low, the oil pump will drawing air along with the A/T fluid, which will cause bubbles to form. This will in
turn cause the hydraulic pressure to drop, which will result in late shifting and slipping of the clutches and brakes.
In either case, air bubbles can interfere with normal valve, clutch, and brake operation. Foaming can cause A/T Fluid to escape from the transaxle
vent, in which case it may be mistake for a leak.
6. Securely insert the dipstick.
NOTE: The A/T fluid and filter should always be replaced in the following conditions:
-
When trouble shooting the transaxle
-
When overhauling the transaxle
-
When the A/T fluid is noticeably dirty or burnt (driving under severe conditions)
Further more, the oil filters are special filters which are only to be used for the transaxle.
