just want to report that I've now got one season on my doubler, and there have been zero problems to report. The product works as advertised. The manual needs work. /forums/images/icons/smile.gif I broke one tranny this year (my fault for not skidplating the bottom of the tcase), but the doubler never skipped a beat. I can put the truck on literally ANY incline in low low and it will sit there with no brake and no gas. Coming down with the Auto (TH400) is awesome on hills, great compression braking. Thanks ORD. Good product. Tim.
