If there is no slope to cause force on mechanical park lock and the shifting is harder in first time than later in the day, then it must be somethning else. Maybe some stiff grease on linkage or lock mechanism, which gets softer as the transmission gets warmer. Just a wild guess.

Or as the gearbox ( aluminium ) warms it expands mote than the (steel ) pin and allows it to slide more freely.  Overnight temperatures in most countries are colder than daytime.

I've been monitoring it and during the day of many stops and engaging Park it can be sometimes be very easy to move from Park to Reverse but most times it requires a fair amount of force, not a worrying amount but definitely a lot more than a light touch. First engaging the handbrake firmly doesn't appear to make much difference.

Is that normal behaviour on the CVT?

It's not normal. Force should not be needed.

No force should be required at all. Foot on brake pedal, press the lock on the gear selector, move lever. virtually no resistance felt.

I am surprised by by the antipathy shown by some to the I-shift. I feel that the problem is twofold; the owner needs to understand both the driving AND the mechanics to get the best from the Jazz I-shift. The car needs to be set up correctly, well maintained with the recommended oil and wheels/tyres. Honda recommend 0W-20 synthetic oil and expensive spark plugs; why would you compromise the life of your motor by using anything inferior?
Mine has nearly 170k miles and does not use oil or coolant. It out-performs many larger engined vehicles.
The only concession to original spec I have indulged in Mitchellen tyres which I inflate a little lower than original.
My driving is a mix of heavy urban and long distance Motorway/A roads. It is by far the best car I have owned.

   170k?   Have you had any work done on the gearbox actuators?

Only thing I can think of ( and it happened on some conventional automatics ) is someone was a bit hasty to push selector into 'P' before car came to a full stop and the locking device got distorted.

I've never had an automatic before, so Im not really sure how much force is more than normal or reasonable. I just noticed sometimes it's very light and other times it's harder, normally harder.

Is the amount of force necessary for you to get in and out of park the same at all times, even if parked on a slope?

What generation Jazz is yours?

Go and test drive another one, and see how it compares with yours.

Just to clarify, when more force is required to go from Park to Reverse that's typically only when the engine is running, if the engine is off it's normally much easier to change.

On my Mk2 CVT I find on harder acceleration at low speeds the drive feels a bit rattley much like lugging the engine sounds, at higher speeds when you accelerate it just pulls and is very quiet. That's on the 1.3(same engine as the 1.4).

The Mk1 CVT I drove seemed to be the opposite, less noise at the lower speeds but very noisy at highway speeds(which I have read is a common complaint). Probably due to the low down torque of the 1.4dsi engine.

Anyone else noticed the above?

I've been monitoring this, sometimes going in or out of Park is very easy but generally not, all the gears seem to require a fair amount of force to click over the shift pawls/points, none of them are particularly light.

If I recall it was a similar shift feel in the Mk1 CVT's I drove, I definitely didn't notice anything out of the ordinary when I first drive the Mk2.
