Its time for me change the trans fluid and filter. I removed the rubber gromit looking for the T C drain plug and it wasnt there!!! I did turn the engine all the way around three time to make sure I didnt miss it. Is there one on the 4R100 Trans? If not is it possible to get all the old fluid out?

 

There are no drain plugs any longer.

HERE is how I change my trans fluid. It works great!

 

Drain plugs went away around 2001. I got one of the last R70W transmissions with a torque converter plug in it.
