Transaxle/Transmission | Automatic Transaxle System |
The transaxle should be overhauled under the following conditions.
Transaxle fluid: GENUINE HYUNDAI ATF SP-II, DIAMOND ATF SP-II or AUTRAN MMSP-II.
Low fluid level can cause a variety of abnormal conditions because it allows the pump to take in air along with fluid. Air trapped in the hydraulic system forms bubbles which are compressable. Therefore, pressures will be erratic, causing delayed shifting, slipping clutch and brakes, etc.
Improper filling can also raise fluid level too high. When the transaxle has too much fluid, gears churn up foam and cause the same conditions which occur with low fluid level, resulting in accelerated deterioration of automatic transaxle fluid.
In either case, air bubbles can cause overheating, and fluid oxidation, which can interfere with normal valve, clutch, and servo operation. Foaming can also result in fluid escaping from the transaxle vent where it may be mistaken for a leak.
