The liquid is added through the dipstick hole with the engine running. With the parking brake applied and the brake pedal depressed, alternately move the selector lever to all positions. Finally, move the selector to position P and check the fluid level again.

To replace the working fluid, the old one must first be drained through two holes located in different places. The plug of one of them is in the crankcase and is shown in fig. 343. The other is screwed into the torque converter. To gain access to it, it is necessary to manually turn the crankshaft of the engine until the plug appears in the hole in the torque converter housing, as shown in Fig. 344.
When changing the working fluid, proceed as follows:
- take a short car ride so that the fluid is warmed up, but not too hot;
- place the car on supports and place a container of approximately 6 liters under the gearbox;
- Unscrew the plug from the drain hole in the gearbox housing with a hexagon and allow the fluid to drain. It is important that the liquid is not too hot. Feel the crankcase: if it is very hot, wait a while until you can touch the crankcase with your hand. After draining the fluid, check the sealing ring of the plug and replace if necessary. Then wrap the plug and tighten with a torque of 14 Nm;
- rotate the engine crankshaft by installing the head on the crankshaft pulley bolt until the drain plug in the torque converter is accessible. Unscrew the plug with a hexagon and wait until the liquid drains. Then tighten the plug with a torque of 16 Nm. Replace sealing ring if necessary;
- Pour the recommended fluid into the gearbox. The above amount will not go in completely, because some of the old liquid remains in the box. Therefore, from time to time, you should check the level on the dipstick. Finally, insert the dipstick and check the fluid level as described earlier.
