Bang on , the only drawback with this is for owners who live in the country ( like me ) or going straight onto a freeway if in a city, then it's pretty inefficient , unless you have manual lockup , the only problem there is if locked up too early the trans will run too cold which is not great either.


surfingooner Discorevy, What is torque converter lock up and how and why. Please excuse my ignorance, but keen to learn and understand what makes the beast tick

Hi , see Pedro's link , that's a really good explanation, but essentially lock up makes it pretty much a direct drive between engine to output shaft.
