2003 Lincoln Town Car - how to flush old tranny fluid from torque converter?
 

As most on this forum know, most vintage mercedes automobiles have a drain plug in the torque converter of the transmission. this allows for a total transmission fluid drain which is a good thing.

I recently read that for cars that do not have such a drain plug, people take off one of the transmission hoses that goes to the cooler and have a helper start the engine while watching the old fluid come gushing out.

This facilitates total flushing out the old transmission fluid. I have never done anything like this, is it actually possible? Is there anything I need to watch for if I try this? Is it possible to install a drain plug in the Lincoln's torque converter?

All input and advice is appreciated.

Even if possible to install a drain plug I wouldn't for a regular service, just not worth it in my opinion and it will throw the rotating assembly out of balance. I'd drop the pan, replace the filter, pan gasket and add genuine Ford fluid. You could remove the return line at the radiator and let it drain into a container but I wouldn't unless the old fluid was really bad. Some disagree but I also like to add a bottle of Lubegard.

Might be better to ask on a Ford/Lincoln/Mercury forum

Never done it , but if you disconnect one of the 2 oil cooler lines , use a hose into a bucket , run engine a short time , the old fluid will go into the bucket , keep filling and doing it until clean fluid come out .

Its the same for almost all transmissions unless you have a certain situation where there is a thermostat in the system or doesnt flow out there till in drive or reverse.

Trying wont hurt
