Customer Question

I have a 2004 xjr and I was wondering what would cause a small surge in the rpm's between 30 - 50 mph?

Usually a rpm surge when driving at a steady speed is from the torque converter. Before replacing any components the Transmission Control Module should be cleared and updated with specific software which will usually correct this problem. Of course we should also have the fluid level and condition checked but since there is no dipstick this is not easily done.

Sounds like I need to bring o to the dealer to have a conclusive diagnosis?
Is it damaging to keep driving it until I can get it in to the dealer?
Expert:  Richard replied 4 months ago.

No you should not cause any further damage.
