They know their shit when it comes to auto trannies.
They completely built me the tranny I wanted, kevlar bands, clutches, completely go through and modify the valve body...amazing stuff. The tranny in my jeep would downshift IMMEDIATELY whenever I wanted to, and it really held the power and shifts well. It would litterally shift faster than I could snap my fingers, no lag or sliding into gear, even at WOT. Simply amazing for an automatic.
If I were building up my Lude and didn't want the manual (aka Show or drag car), then I would definately go through them. They build them so well that litterally the ONLY benefit of having a manual at that point is the ability to manually slip the clutch in corners...it just plain shifts faster and more efficient than you ever could with a manual.
