Sure, the two small lines that connect to the bottom of the radiator are from the transmission. Disconnect them and add some rubber tubing to each and after you determine which is supply and which is return attach a funnel to the return and a bucket to the supply. I can’t remember which is which but a quick start will show you. Have a friend start the car and hold both over a bucket and wa la! You’ll need about 8 quarts of fluid. Just pour the fluid in the return until it starts to come out like new and your done. Also if you’re thinking about installing an external transmission cooler now is the time to do it. Just eliminate/bypass the one in the radiator. Oh yeah don’t do this with the trans in reverse = lots of pressure.

Interesting - is there any danger of the transmission running dry by doing this? - I mean is it possible to add fluid to the return hose fast enough ? If you add too fast could you overfill ? Does the return hose dump into the pan or go elsewhere >? I would think it might be best to match the normal return hose flow rate/pressure ??
