Guess what? They originally sold me the wrong one. The one I had on the Durango since August was for a Durango with 5.2 or 5.9. No wonder it was killing the mileage.

This got me to thinking though, what would happen if someone would put a 4.7 clutch on a 318 (5.2) or 360 (5.9) Durango, Dakota , or Ram? Would you gain a little better gas mileage? Would it overheat? Inquiring minds want to know.
