The car drives great below 30 mph and over 70 mph. While driving between the two levels, when giving gas I am fine. While trying to maintain a certain speed, a strong whining sound takes over as though it is desperate for gas. When using cruise control, the problem lessens but is still present. An Aamco transmission shop fixed an oil leak and hooked the vehicle up to update all the necessary codes, problem still exists. A Jaguar specialists in Naples Florida (also works on Aston Martins) said they never experienced this before.

I saw on a previous Jaguar forum where someone else had this problem but a solution was never given. Please help!
