| AUTOMATIC TRANSMISSION FLUID CHECK CAUTION When replacing the transmission with a new one, overhauling the existing transmission, or driving in a harsh condition, the A/T fluid cooler line should always be flushed out and A/T fluid should be replaced with a new one. Drive the vehicle until the A/T fluid temperature reaches the normal temperature (70 - 80°C) NOTE: Measure A/T fluid temperature using MUT-II/III.
| NOTE: Check the oil level referring to the characteristics chart shown at left if it takes some time to reach the normal operation temperature of A/T fluid (70 - 80°C). Park the vehicle on a level surface. Move the selector lever to all positions to fully charge the torque converter and the fluid lines with A/T fluid, and then move the selector lever to the N position. After wiping away any dirt from around the oil level gauge, pull out the oil level gauge and check the level of A/T fluid. NOTE: If the A/T fluid has a burnt smell, or if it has become very contaminated or dirty, it means that the A/T fluid has become contaminated by minute particles form bushings (metal) or worn parts. In such a case, the transmission needs to be overhauled and the A/T fluid cooler line needs to be flushed out.
| Check that the A/T fluid level is between the HOT marks on the oil level gauge. If the A/T fluid level is too low, add more A/T fluid until the level reaches between the HOT marks. Automatic transmission fluid: DIA QUEEN ATF SP III NOTE: If the A/T fluid level is too low, the oil pump draws air into the system along with the A/T fluid, and air bubbles will thus from in the fluid circuit. This will cause a drop in fluid pressure and cause the shift points to change and the clutches and brakes to slip. If the A/T fluid level is too high, the gear will churn the A/T fluid and cause bubbles to develop, which can then cause the same problems as when the A/T fluid is too low. In either case, the air bubbles can cause overheating and oxidation of the A/T fluid, and also prevent the valves, clutches and brakes from operating normally. In addition, if bubbles develop in the A/T fluid, the A/T fluid can overflow from the transmission vent holes and be mistaken for leaks. Securely re-insert the oil level gauge.
