I just had my whole connector replaced yesterday... same deal... left it for a few days while I was on a hunting trip... came back and there was a puddle... the dealer had the part in stock... luckily I checked on the fluid before I had to bring it in and they had it there by the time I had my appointment... but the tech said they have to use a scan gauge to measure the fluid level to know how much to put back in there... he said exactly how they do it but I forgot I just remember thinking well I don't have the tools to do that... so I don't know about doing it yourself as far as putting the right amount of fluid back in...... 4400 miles on it....... later
