Im new at this tuning thing but i am trying to lock a transmission in 2 gear for a circle track car. I only want the car to run in 1st and 2nd gear. How do i lock out 3rd and 4th? Its a 2009 Pontiac G6 with a 3.9 and i believe it has the 4t45 transmission. what are good pressures to look for? How do i make the torque convertor go in to lock up at a certain rpm?
