I just put on a set of 35-12. 5-17 BFG muds and now have some questions. First off, is there a product that I can get that will allow me to control the torque convertor to lockup in OD under 50 mph? I have no problems with how the transmission acts in the first few gears, but I sure would like to be able to get full lock in OD while cruising the flats @ 45 mph. My truck just wont do it. Also, is the TQ lockup controlled by the computer. Thanks for any input.
