Searched quite abit and really couldnt find anything. I have a 48re swap in my 09 so my 4 low is not working yet. I have a sled pull coming up this weekend and I am wanting to pull. Has anyone ever tried ever pulling in 4 high before. I have a stage 6 ats with pcs controller. Not sure if I can go in 2 gear or not. I am thinking I will only be able to go in 1st gear, but my main concern is the torque convertor not being locked in first. 37" tires with 3.73 rearend.
