1996 Ford Thunderbird LX (219k)
Okay that doesnt sound too complicated. I have a gravel driveway so jacking it up might be tough. Ill definetly replace it in the near future. How long you think is safe to drive it? I need 500 more miles out of it.A full fluid and filter change should eliminate the shudder, it always has for me. This is not just dropping the pan, which only gets a few qts.
Run the cooler return line into a bucket and run the car until it starts to sputter. Then drain the converter and drop the pan (which will be almost empty) to change the filter. That should be 11 or so qts. Always use a Ford gasket, which is re-usable, but I like to start with a new one.
