Billet aluminum servo is FULLY adjustable outside the transmission! Much easier to adjust when building on a bench or re-adjust after break-in period. The adjustability also allows for band adjustment during routine maintenance without dis-assembly or the normal mess involved. Adjustments are MUCH easier to attain and more precise with the incremental adjuster incorporated into the cover. No more repeated install/remove to add or subtract shims and no more 'tips' beat on the end of the servo pin and again; no repeated install/remove to grind tip for imprecise adjustment. This servo can be installed and adjusted with transmission in the vehicle with basic hand tools. If you have any suggestions...eh, ummm, I know that leaves me wide open on this site but, feel free to suggest away! Thanks, John.
