We use a wet clutch, when you would move uphill at very low speeds it would slip almost constantly. We cool this clutch with CVT oil, this is pumped trough the clutch by our CVT pump, this pump is directly connected to the engine. So yes, when not driving as you should with a CVT (and you cannot know this as this is new) you can overheat it. Please compare to manual, if you would keep it on a hill only using the clutch you would burn it.
What to do? avoid long slipping clutches by applying enough throttle when moving uphill, the engine will produce enough power for us to close fast without long slipping period. Shift to N when you can, this will have a cooling effect on the CVT, if possible in N apply little throttle till lets say 1500rpm, this will rev up the pump and increase cooling.
these tips are only for extreme conditions! all other condition drive as you want!
Our CVT's are tested under extreme temperatures! Worst case scenario clutch will open, resulting in no drive as we measure temperature and in order not to break the CVT we will open clutch. You will have to wait a few moments, key on and off and there you go again, this is no breakdown!
Need more specific info on the following:
1) Do we know when the cluth is fully open? is there an indication or behaviour that we can observe?
2) as you said "when you would move uphill at very low speeds it would slip almost constantly", how slow is the slow (car speed and engine rev)?
3) The tips in the "what to do" is for extreme conditions. could you elaborate more on the conditions?
4) When u said the CVT is tested under extreme temperature, how extreme is it?
5) If the car is in extreme condition, i believe the CVT oil might be degraded earlier than expected. Is there a way for us to check if the CVT oil is still at its functional condition to lub and cool the CVT?
I am currently driving a Honda City with CVT and it is working fine after 150k+ km. it has the idle neutral behaviour as you mentioned above. As we know, City CVT is not supplied by Punch. Thus, i want to make sure i drive like what Punch recommends in order to get the best out the CVT, yet with minimal wear and tear. i am getting my Exora soon in the next 2-3 weeks.
