I am about having the transmission fluid change correctly by dropping the bottom pan, let it drain, servicing the filters and screens, cleaning the pan of debris and filling with new, Mecron V fluid. It has never been done before car has 63.000 miles. Now, my question is:
1) Does a 2003Crown Victoria have a plug covering a screw in the torque convertor that allows to drain about 98% of the fluid without flushing?
Heres your answer.On most tranys if you drop the
pan you will get approx 5 or 6 litres of the old fluid out.The
rest will stay in there.Now to do the trany properly,depending
on the mileage and condition of the trany when the fluid is
being changed.
1st Drop pan
2nd Drop as much fluid as possible
3rd change filter
4th put pan back on
5th hook up to a machine that can put new trany fluid in and
remove the old fluid at the same time. Also known as flushing
in the shop.What you have to keep in mind is some tranys do
not like the fluid being flushed by the machine(stirrs up the dirt
and can make some valves in the valve body start to stick) It
is best left to a trany shop or Dealer that has ran into what
I am talking about.

I have determined that I do have a drain plug on my 1997 GM on the torque converter which will allow me to drain more of the old fluid out other that the small amount you get out just dropping the pan...Thinking about NOT doing a machine flush on this 10 year old vehicle...Just will change filter and replace as much of the fluid as I can drain out..
Not sure if the 2003 has this converter drain plug or not..Need to crawl under the vehicle and look for a plastic cover plate..If plate is there then it may conceal the drain plugs on the torque converted...May have to turn over the engine by hand to get drain plug lined up with inspection hole you are looking thru...
Converter may actually have two such plugs...
I think what I am going to do is to drop the pan, clean it, let the fluid drain then change the filter. After that, I was thinking driving about 5.000 miles and change the filter again since all the cleaning in the transmission is done by the fluid and all the dirt gets captured in that filter. I really do not like the idea of flushing it because you never know what car was on the machine before, could be something with the transmission on its last leg. All that dirt plus debrits that can get into my transmission, etc. This way, nothing else but Mecron will get into transmission.
Yep....That is exactly what I am planning to do as well...
Do not think we can go wrong doing that....Couple filters and bunch of quarts
of Mercon still way less expensive than a tannie rebuild....
If you catch the fluid in a perfectly clean container and then take the container out in the sunlight you will see just how much metal junk you had in the trannie and pan..Sun makes them sparkle...
Frank n texas, keep my updated on how it went with your car. I am about to do this sometime this month. Fluid in it still looks pristine, although when it shifts under moderate acceleration light nudge can be felt. Also, this happens when shifting from Reverse to Drive and vice versa.
