Re:


Thanks jalaski!

Think I need to do a bit of research when it comes to driving in that mode. Are you meant to keep your foot on the accelerator when you go up/down the gears? Is it bad for the transmission to use this mode for prolonged periods?

Cheers

Re:


I lift my foot off when am about to change gears manually, but I think it doesn't make a difference. Anyway, I have used it for prolonged period of time as it just felt a bit weird emoticon

In Manual mode, personally, I keep accelerating with the foot down when down-changing during a hill climb and when up-changing for maximum take-off at the lights.

The foot is naturally off the accelerator when dropping down a gear to use engine braking on a downhill run.

There is no clutch interface so when you do select a gear with the + (push stick forward to go up) and - (pull stick back to go down) gear selector, it allows the gearbox to select that particular ratio.

As I understand it, all the manual select does, is to tell the continuously variable gearbox position/ratios cones to use the only the positions which correspond with the normal Manual (or Auto) gearbox ratios.

Being Semi-Auto in that mode, you don't need a clutch and if the gear ratio you select is too high for the load, it will still decide to operate in a gear it regards as more appropriate for the load on the engine/gearbox (up to, but not exceeding , that which you chose).

e.g.: You might select 5th on a steep hill at 2000 rpm, but that only tells the manually over-ridden CVT that you are willing to go up to 5th.

The gearbox 'brain' may disagree.

The gearbox brain then decides which gear is the highest it is prepared to accept and use without damage... it might prefer 4th (or even 3rd) when you choose 5th , so it will only change up to your selected gear when the transmission load is low enough to allow 5th comfortably within its preferred rpm and load range.

Note: I would hope that anyone using the manual over-ride was actually skilled enough to improve on the CVT default selection by driving it as if it was a real Manual and selecting the rpm and load to get the best from the combination.

Bottom line: it is safe to experiment with the joys of Manual over-ride as that gearbox does protect itself from short-shifters.

However, it does allow over-revving at relatively low speed in a wrongly selected low gear as it won't change up beyond the highest gear available in its manually constrained selection. Do that at your own peril.

Re:


I came from a ford before the Xy and it's the opposite direction when in manual mode. Imagine my surprise the 1st time I went manual!

Re:


I Came from a ford XT as well and honestly the exy is more logical, just like the Toyota.

Why the hell Ford thought people would push forward to shange down and pull back to change up is beyond me.

But this is just 1 of the several hundred things I hated about the XT ford

The Exy maynot be a beautiful car
It may bot be as powerful car
It may not be as economical a car
It may not even be a quiet car in comparison to the ford

Buts its a damn site better in build quality, ease of access and egress, better for the legs,(bent not straight out in front like the ford)
It can carry more much easier, its a far better car for my needs and its all wrapped up in a good looking (to me) functional box shape

Im still getting used to the quirky gearbox.
Its spooky watching the tacho stop at 2500 rpm while the speedo keeps heading north.
I also admit its better on the freeway than stop and start driving, but I drive 85k to and from work each day on the freeway.

I like my car
