I have a 68 plate Jaguar E pace P300.

I’ve received it back from jag have it had gears adaptions and updated TCM software.

but when I put my foot down to accelerate the car can rev up to 6/7RMP before changing gear and when it changes gear the can judders like a lost of power then take my foot of the accelerator then will jerk into gear I think by the way this is an automatic 9 speed

 

Take it back, they did something wrong. Take a video when the problem arises and show it to the service manager.
