I've already used the search function, but have not found much info for clutching the 09-10 with engine reverse. The sled has the following done to it, SLP pipe kit, pcIII, BDX intake, 54/66 gears, and a Cutler torsion kit. I've been told that I need to use the Cutler orange spring for my reverse to function, but it seems like it might be holding back the upshift, I was running a 42 helix, but the helix bolts snaped so it is toast. Has anyone gotten the torsion kit to work well with the orange spring?
