Note: Due to the complexity of the automatic transmission device, it is very difficult to properly diagnose and troubleshoot this unit on your own. For problems not listed below, contact your dealer's service department or automatic transmission specialist. Do not rush to remove the transmission if you suspect that it is faulty, since most tests are performed without removing the block.
Fluid leak
- Transmission fluid is usually dark in color. Do not mistake engine oil for fluid leaks, drops of which may fall on the transmission.
- To determine the source of the leak, first remove all dirt from the gearbox housing and the area around them using a special compound or steam. Make a short trip at low speed so that the leak is not blown away from the source by the air flow. Jack up the car and determine the location of the leak. Common Leak Locations:
- a) Sump
- b) Level connection
- c) Branch pipes connecting the transmission to the cooler
Transmission fluid is brown or smells of burning
- Transmission fluid level is low or needs to be replaced
