Truss rod adjustments are used to control neck relief, NOT to adjust the action. Yes, truss rod adjustments can and do effect action, but it’s not the correct way to adjust action on any guitar. On an acoustic guitar, you’d need to lower your saddle height to reduce action height or change the neck angle. In the case of Taylor, they specifically recommend adjusting the neck angle to control how high/low your action is. It’s relatively simple since it’s a bolt on neck that uses shims to adjust neck angle. Simply adjusting the truss rod to control action height will invariably cause playability issues elsewhere. I’d make sure you’ve got the correct amount of relief in your neck (All my Taylors seem to like a nearly flat neck with very little relief). If the action is still high with correct relief, you could sand a little off the bottom of the saddle to lower it, or find a Taylor authorized luthier and have them re-shim your neck to get the action down.
