I am looking for a converter that will allow more torque to the wheels. I have the stock converter with my TH400. I am looking at the B&M Traveler Series converter that stalls 300 rpms higher than stock. This is supposed to help in pulling heavy loads from a dead stop. Is 300 rpms enough to actually make a difference? Has anyone had any experience with aftermarket converters and is it worth the money at 100 bucks.
