I am a newbie...Just got an 03 GT with 6 spd.....160K miles. The trans fluid has never been changed according to the seller. I cant seem to find a dipstick. I think I found a plug that looks like a drain plug but dont want to drain it without finding a port to refill it. There are a couple plugs on the front side of the gearbox that could be fill plugs that bring it to a correct level..any help appreciated. Jerry in Michigan.
