Found a company that offers either new 5-speed or 6-speed complete conversion kits for the XJS V12 and it looks like a pretty nice setup. Anyone have any experience with this? Upside is better mileage, quicker acceleration, and apparently lower running temperatures. Looks to be me to be a decent option if you are looking at a rebuild or replacement of the standard automatic tranny. Company is "The Driven Man" out of Cookeville, TN FYI. Also seem to have some other nice parts for the XJS, just as an aftermarket exhaust, a complete suspension upgrade, etc.
Any thoughts?
