In AT it is not required to change oil during all term of operation.

The following belongs to number of the most probable places of development of leakages of ATF:

  • Plane of a joint of the block of cylinders and AT (back epiploon of the crankshaft).
  • Place of connection of a power shaft to a transmission.
  • Drain stopper.
  • Jellied stopper.

    1. Clear AT case.
    2. Possible places of leaks sprinkle with a thin layer of chalk or talc.
    3. Make a trial trip on distance about 30 kilometers.

    5. Eliminate leak and fill in oil in a transmission.
