Note:
- (CVT fluid replacement) Jatco, the CVT manufacturer, does not specify the need to replace the CVT fluid, since its use is designed for the entire service life of the gearbox. However, given the operation in the CIS countries, it is recommended to replace the CVT fluid under normal operating conditions every 40,000 - 60,000 km. When operating under severe conditions, it is recommended to reduce the intervals for replacing the fluid.
- This procedure is carried out only if there is no special device for draining the working fluid.
Attention: when replacing or overhauling the CVT or automatic transmission, it is necessary to clean the working fluid cooler lines and replace the working fluid in the CVT or automatic transmission.
1. Disconnect the hose shown in the figure, connecting the CVT/AT and the working fluid cooler built into the radiator of the cooling system.
2. Start the engine and drain the working fluid through the hose when the engine is idling and the CVT or automatic transmission selector lever is in the "N" position.
Note: After starting, let the engine run for no more than 1 minute. If the working fluid drains before this point, stop the engine immediately.
The volume of drained working fluid is approximately 3.5 l
3. Unscrew the drain plug on the bottom of the variator or automatic transmission housing and let the working fluid drain into the prepared container.
The volume of drained working fluid is approximately 2.0 l
Variator.
Automatic transmission
4. Install the drain plug with a new gasket and tighten the plug to the specified torque.
Tightening torque - 32 +2 Nm
5. Fill the CVT or automatic transmission with fresh working fluid (ATF) through the guide tube of the working fluid level dipstick.
Recommended working fluid - DiaQueen ATF SP-III or equivalent
Filling volume: approximately 5.5 l
Attention: stop pouring working fluid into the variator or automatic transmission if it is impossible to fill the volume specified above.
6. Repeat the procedure in point "2". Note: drain at least 8 liters (CVT) or 7 liters (AT) through the cooler hose of the working fluid when performing the procedures in points "2" and "6". Then drain some more working fluid and check for signs of contamination of the working fluid. If the working fluid is contaminated, repeat the operations in points "5" - "6".
7. Fill with fresh working fluid through the guide tube of the working fluid level dipstick.
Filling volume: approximately 3.5 l
8. Connect the CVT or automatic transmission fluid cooler hose (disconnected in step "1"), clean the dipstick and its installation location from dirt, then securely insert the dipstick into place.
9. Start the engine and let it idle for one to two minutes.
10. Move the CVT or automatic transmission selector through all positions, then set it to the "N" position.
11. Make sure that the working fluid level is at the "COLD" mark on the working fluid level dipstick. If the level is below this mark, add the required amount of working fluid.
12. Drive the car until the working fluid (ATF) in the CVT or automatic transmission reaches normal operating temperature (70 - 80°C), then recheck the working fluid level. The working fluid level should be within the "HOT" range.
Total filling capacity:
- Variator - 8.1 l
- Automatic transmission - 7.7 l
Note:
- The "COLD" mark on the working fluid level dipstick is for reference only. Always check the working fluid level in the variator or automatic transmission in the "HOT" range on a warmed-up variator or warmed-up automatic transmission.
- It is recommended to read the temperature of the working fluid (ATF) using the MUT-II tester.
13. If the working fluid level is above the "HOT" range of the dipstick, drain the excess working fluid through the drain plug. If the working fluid level is below the "HOT" range of the dipstick, add working fluid to the variator or automatic transmission.
14. Insert the fluid level dipstick securely into its guide tube.
