Attention! Unsatisfactory automatic transmission performance can be caused by poor engine performance, improper adjustment, malfunction of hydraulics and mechanical parts, interruptions in the operation of the processor unit.
Preliminary checks
1. Warm up the transmission by driving.
2. Check fluid level.
- A) If the level is below normal, then restore the level by adding fluid, then fix the leaks.
- b) If the level is above normal, then remove excess fluid and check the condition of the drained fluid. The presence of engine coolant in the transmission fluid indicates a leak in the radiator.
- V) If the fluid foams, change the fluid, check for traces of engine coolant in the transmission fluid, or watch the level rise to indicate engine fluid has entered the transmission.
3. Check engine idle speed.
Attention! If the engine runs intermittently, find out the cause and correct it.
4. Check the condition of the throttle cable. Adjust the cable if necessary.
Attention! On a warm engine, throttle cable performance may not be satisfactory. Check its operation on a cold and warm engine.
5. Check the gearshift linkage for smooth operation and linkage adjustment.
Fluid Leak Status Check
6. Liquid leakage is easily identified by the dark red color and is eliminated by replacing the seals or gaskets. To detect a noticeable leak, park your vehicle after driving a few miles over a blank sheet of cardboard or paper. After about 2 minutes, the leak can be detected. If the leak is weak, then carefully clean the crankcase and check the seals after the trip.
5. If the leak is located, then determine the cause of the leak and the method of repair (for example, replacing the gasket cannot eliminate the leak if the split planes are deformed).
6. Before repairing the leak, analyze the causes of the leak and determine the nature of the repair work, since many types of repairs cannot be performed independently.
7. A leak from under the gasket may be the result of an increase in pressure or liquid level due to clogging of the ventilation holes, deformation of the pallet or its split plane, inconsistency of the used sealant brand with the recommended one, defects in the casting of the pallet. Check periodically the tightness of the seal of the pointer pipe and the speedometer gearbox.
8. Seal leakage can be caused by increased pressure or fluid level due to clogged vent holes, incorrect seal installation, damaged shaft seal, or worn shaft bearing.
9. Crankcase leak due to casting defects. Check that the fluid cooler hoses are secure.
10. A leak from the breather or from the filler pipe indicates transmission overflow, coolant ingress, porosity of the crankcase material, incorrect position of the pointer, clogging of ventilation and drainage channels.
