Transmission whine?

Hello, the filter is fairly straight forward however getting the level right is tricky if you do not have a scan tool that can read live data, specifically transmission fluid temperature. This is required to set the level correctly. I will list the procedure for replacing the fluid below, and be sure to use Nissan NS-3 or equivalent CVT transmission fluid. For changing the filter, drain the fluid as described and then remove the transmission pan bolts. Once removed you will see the large plastic filter with one bolt attaching it to the valve body (see image showing exploded view). Remove and replace the filter, gasket, and pan, and follow through the procedure for filling and setting the fluid level.

1. Select “Data Monitor” in “TRANSMISSION” using CONSULT.
2. Select “FLUID TEMP” and confirm that the CVT fluid temperature is 40°C (104°F) or less.
3. Check that the selector lever is in the “P” position, then completely engage the parking brake.
4. Lift up the vehicle.
5. Remove the drain plug and overflow tube and drain the CVT fluid from the oil pan. Exploded View.
6. Install the charging pipe set (KV311039S0) (A) into the drain hole.

(see image 1)

AUTION:
Tighten the charging pipe by hand.
7. Install the ATF changer hose (B) to the charging pipe.

CAUTION:
Press the ATF changer hose all the way onto the charging pipe until it stops.

8. Fill approximately 3 liter (2-5/8 lmp qt) of the CVT fluid.
9. Remove the ATF changer hose and charging pipe, then install the drain plug.
NOTE:
Perform this work quickly because CVT fluid leaks.

10. Lift down the vehicle.
11. Start the engine.
12. While depressing the brake pedal, shift the selector lever to the entire position from “P” to “L”, and shift it to the “P” position.
NOTE:
Hold the lever at each position for 5 seconds.

13. Check that the CONSULT “Data monitor” in “FLUID TEMP” is 35°C (95°F) to 45°C (113°F).
14. Stop the engine.
15. Lift up the vehicle.
16. Remove the drain plug and then drain CVT fluid from oil pan.
17. Repeat steps 6 to 16 (one time).
18. Install the overflow tube.

CAUTION:
Be sure to tighten to the specified torque. If it is not tightened to the specified torque, the tube may be damaged.
19. Install the charging pipe set (KV311039S0) (A) into the drain hole.

CAUTION:
Tighten the charging pipe by hand.
20. Install the ATF changer hose (B) to the charging pipe.

CAUTION:
Press the ATF changer hose all the way onto the charging pipe until it stops.

21. Fill approximately 3 liter (2-5/8 lmp qt) of the CVT fluid.
22. Remove the ATF changer hose and charging pipe, then install the drain plug.
NOTE: Perform this work quickly because CVT fluid leaks.

23. Lift down the vehicle.
24. Start the engine.
25. While depressing the brake pedal, shift the selector lever to the entire position from “P” to “L”, and shift it to the “P” position.
NOTE: Hold the lever at each position for 5 seconds.

26. Check that the CONSULT “Data monitor” in “FLUID TEMP” is 35°C (95°F) to 45°C (113°F).
27. Lift up the vehicle.
28. Remove the drain plug and confirm that the CVT fluid is drained from the overflow tube.

CAUTION:
Perform this work with the vehicle idling.
NOTE: If the CVT fluid is not drained, refer to “Adjustment” and refill with the CVT fluid.
29. When the flow of CVT fluid slows to a drip, tighten the drain plug to the specified torque.

CAUTION: Never reuse drain plug gasket.

30. Lift down the vehicle.
31. Select “Work Support” in “TRANSMISSION” using CONSULT.
32. Select “CONFORM CVTF DETERIORTN”.
33. Touch “Erase”.
34. Stop the engine.

Hope this helps,

The design of the plug and overflow tube is made so that you can remove it with the transmission running and the excess fluid will run out of the overflow tube. The drain plug threads into the overflow tube and then the tube is threaded into the pan. This has to be done with the transmission fluid at the correct temperature. Once the fluid stops flowing you can put the plug back and tighten.

William

Yes after you have replaced the filter and are prepared to refill the transmission, you will need to add fluid the fluid as described and then close the drain plug. Once at temperature remove the plug and allow the overflow to drain. I would save the fluid drained out to measure and put back in the same amount and adjust from there.

William

This is why I measure what comes out. You should go through around 5 to 6 quarts of fluid. The design of the overflow is to let you know it's full when it slows to a drip.

William

When you're ready to fill it, make sure both plugs are tight and sealed. Fill it with the equal amount of fluid that you drained out, and run it until the transmission reaches the optimal temperature. Once it reaches temperature, remove the first plug and what drains out will be the overflow. When that stream stops, you're done.

William

If you put the bolt back it while there is a light stream, I don't think it will hurt it, but it will technically be overfilled by a little.

William

I would say so, yes.
