How do you change the transmission fluid in a 1953 Mercury Monterey 329 flathead engine?
Most Mercury Montereys must be drained (transmission) by
removing the big inverted nut that holds the filler tube in place.
This is the way mine works. I have heard that some had a drain
plug, but have never seen one. I have also seen suggestions that
the best way was to remove the pan, but these were only guesses in
the blind because you can't remove the pan without removing the
dipstick tube in any case.
PS: This all assumes that you have an automatic trans. Also, unless you or someone else has swapped engines, the 53 Merc flathead eng was 255 cu.in. The ford flatheads of that era had a 239 in. eng. so maybe you got the numbers inverted???????
PPS...I have a chilton manual for this period, that goes up to 1953, so email me if I can look up anything else for you, and I'll try to help
slave cylinder location in the Mercury mystique the slave cylinder is located in the transmission. it is connected to the release bearing. the onbly way to change the slave cylinder in this perticular car is to pull the transmission. stupid desing but its a ford so this kind of briliant thinking is expected..lol
The transmission on a 2000 mercury Cougar is on the drivers side. If your planning on removing the tranny, the subframe must be removed. If your wanting to change the filter you are out of luck...it is deep inside the transmission. The pan on the side of the tranny toward the front of the car covers the valve body.
