Jolt selecting drive when first starting. (CVT)

[Laurence]

A few times I've had a jolt from the transmission when I first take it out of park after starting up. After the initial jolt everything is fine. It's probably after the car has been unused for a week or so. 

Has anyone else experienced this?

A jolt ?

 

Have you driven automatics before ?

 

Most automatics will produce a (small) 'jolt' when initially shifted into drive as the auto-transmission loads up ready to move off.

Keep the footbrake in until you are ready to move off.

They will also move (settle) forward or backward (depending on the slope) a little when parking up unless you apply the footbrake first.

 

It really depends on the magnitude of your jolt whether you have a problem, or, more likely, everything is OK.

How are you parking?

Put vehicle in neutral, before the parking brake is applied, otherwise the gearbox is under tension against the parking pawl pin.

I found this. I had an auto Merc with the gear select on stalk and auto electric brake (my first auto), then got the Vellfire and wondered why I had a jolt when I moved house and parked on sloped drive. I thought the gearbox was on its way out, then worked out to put parking brake on then into park

I have been driving automatics for about 35 years now. Occasionally when I drive a manual I forget and wonder why it's not changing gear itself!!

I always park in the same place on a virtually level drive. I'm inclined to think the last two replies are hitting the nail on the head. It's quite possible I have let it roll forward in park before applying the parking break and then selected drive with the transmission under tension. 

It's only happened 3 or 4 times in just over a year. 

Many thanks everyone. I will make a conscious effort to do things in the right order.
