Control of level of ATF in an automatic transmission

Continuous check

The automatic transmission is filled with synthetic liquid under the name Automatic Transmission Fluid. This liquid serves as lubricant means, and also for management of hydraulic pressure in a transmission. That it met the put requirements, ATF should be checked and have «Dexron» designation (with the subsequent control number). Incorrectly chosen liquid can cause damage of a transmission not subject to repair!


  1. At check of ATF should have working temperature that approximately corresponds to a trip on 10 km. The amount of liquid changes depending on temperature. In a cold condition controllable level is too low, after a long trip the too high.
  2. To put the car on the parking brake, to establish the transmission handle on the situation "R", to leave the engine to idle.
  3. To extend щуп ATF located in the direction of movement at the left behind from the engine. He can be learned on the handle. To wipe it follows only rag absolutely dry and not leaving fibers.
  4. To insert щуп and once again to extend it. The amount of liquid between the top and bottom mark makes 0,23 l.
  5. Between both markings transparent ATF should be visible. Marking on a tip щупа is intended only for measurement when filling in case of ATF replacement.
  6. Before ATF it was always transparent and painted in light-red color. Now liquid which in use can be painted in black-brown color is applied.
  7. If ATF on extended щупе smells as ashes, means, there is any damage of a transmission.
  8. At too low level of liquid it is impossible to add simply ATF, it is necessary to check a transmission on leak existence. You should entrust necessary works on sealing to a workshop.
  9. Too high level of liquid can speak laying damages between planetary transfer and a bridge drive.
  10. To check oil level in a bridge drive.
  11. If there is not enough oil, it is necessary to carry out new sealing of both knots in a workshop and to replace ATF.
  12. If oil level is in a drive of the bridge at normal level, in this case surplus of ATF simply suck away from an automatic transmission. Too high level of ATF also can lead to transmission damages.
