OK, I know I'm a dummy. So I was changing the gear oil and removed the gear shift pin, not the drain plug like I should have. I put it right back in, and it went in no problem. I have not started the engine yet. Just wondering if I am going to have any issues with this. Is there anything I should do before I start it to make sure it will shift in and out of gear? Any help or advice will be greatly appreciated. Thanks, Terry
