Seen some post about additives earlier.

What effect would a friction reducer have on a CVT that I think relies on friction for its drive?

The viscosity of the fluid is crucial to the operation. You have valves that control the pressure. Years ago a friend tried this in his Nissan which also had a CVT transmission, only to find that it started to creep a lot when idling at the traffic lights. There were no benefits that he could discern

I think the spec of the 'fluid' in a CVT transmission is so utterly critical I would not depart from whatever Honda specify. The viscosity and lubricity characteristics must be key to performance, reliability and longevity. I certainly wouldn't risk any 'additives' either. Why would you want to take a chance?

My reason is that there is a 'sluggishness' in the cold mornings for the clutch to engage first time - a full 30' to one minute.

As far as I know all CVTs with the starter clutch (All CVTs pre 2009) are slow to engage drive when cold. Mine was like it for all of the six years I owned it. The newer CVTs with a torque convertor are much better.

never put additives in CVT fluid - you may end up with a very expensive repair bill

quote from lubricant manufacturer website --

transmission fluid is the most complex of all lubricating fluids. Not only does it have to reduce friction to prevent wear like all lubricants, but it also has to allow a certain level of friction so clutch materials can engage. Since most OEMs use proprietary frictional materials, virtually every ATF is OEM-specific. In some cases, they're transmission-specific. In addition, fluids must be compatible with all transmission components, operate at both low and high temperature extremes, and maintain constant performance for extended periods.

When I bought our very low mileage, 52 plate CVT, I INSISTED that the supplying dealer changed the transmission fluid. I even went so far as to split the cost of the stuff 50/50, to make sure he fitted the correct Honda part number for the car.
