Hello and welcome to justanswer.com

Do you feel this surge when you are cruising between 30-50 mph?

Customer reply replied 10 years ago
Yes. And it feels strange when it shifts at lower speeds. And when I stop

Relist: Answer came too late.
Jaguar Mechanic: Richard, Jaguar Technician replied 10 years ago
Sorry for the delay.

This is usually caused by the torque converter however before replacing any components we need to have the TCM reprogrammed at the dealer. There is software to fix the surge.

I may have a trans fluid leak. How can I check fluid level & add fluid?
Jaguar Mechanic: Richard, Jaguar Technician replied 10 years ago
Unfortunately since there is no dipstick it is not easy to check and add fluid. There is a plug on the passenger side rear of the transmission that is removed then the fluid will flow out if full. This is done with the fluid warm and the engine running on a level surface or lift.

Thank you Richard. One more, what type fluid should I put in it
Jaguar Mechanic: Richard, Jaguar Technician replied 10 years ago
Only the Jag fluid should be used as you do not want to mix fluids.
