Installed a Ralco short throw shifter from Concept Z Performance, and a few days later I can't get into 5th gear. It seems like I can't push the shifter forward far enough to grab the gear, as you can hear it making slight contact. The transmission is new. Only about 3k to 5k miles on it. All the other gears are fine. No grinding. Would this be related to the short throw shifter? I've installed one on my NA in 2002, with no problems since.
