I have been working on my 60k service, almost all done, just one more thing left.changing out the transmission fluid. It‘s a manual transmission.2004 V6 Ford Mustang. When I looked under.it APPEARS, there is no cover on the drain plug. Is this even possible? How long can a car go without transmission fluid?I have driven the car for 60,000 miles without any mechanical problems. I‘m thinking I might have just found the wrong plugs.
If the drain plug is not installed there will be no fluid and the transmission will grind to a halt in a very few miles. The drain plug on most manual transmissions is either a square head or Allen screw type plug located on the bottom of the transmission. There will also be a fill and level check plug about halfway up on the side of the transmission which may be square head or Allen head or it may be a rubber plug.
If you haven't had any problems yet then your car and tranny are fine. I don't know about Ford, but with my honda I drove a few hundred miles with no tranny fluid. Like a dummy I forgot to fill it when I replaced the tranny. It would make a whiny noise and would pop out of 1st, 3rd, or 5th.
