The No 1 is the filling plug on the top of the transmission.
The No 2 is the check plug on the bottom of the transmission.

ATF fluid level check

We start the engine in P (Park) position and wait to reach the temperature to 30-40 Co. Remove the check plug and we must have a continues small flow. If there is no flow we add ATF from the top filling plug until we get the flow we want.

ATF fluid change

To change the fluid, remove the Allen plug on the oil pan.

Always use CVT only oil fluids
