Is it like a diff? It is the bolt you fill it up from?
Its not like a diff. The 24mm fill plug is located on the passenger side towards the top of the trans. There are 2 plugs on the bottom of the trans. one is the drain plug and one is the check fluid level plug. That's where the 115 degree temp comes into play for checking the correct fluid. I`m old school and I just wait for the trans to get a little heat on it and then check it. I`ve been doing this way for almost 11 years and never had a problem. Get the trans warm and pull the check plug out if it doesn't drip and a little fluid to to the fill plug until it dribbles out of the check hole. Your done.
