I have a 99 SVT, and had the motor replaced under warranty at 32k, it has 40k now. I had the clutch replaced as well since everything was appart anyway. Since this work was done, I have had a problem with an intermittent but regular hesitation when driving at highway speeds. The dealer says the problem is clutch A/C (whatever that is) but the problem was not present before the work was done. The dash was also replaced under warranty and is now worse than it was before.
