This morning I decided to drain a couple of quarts from the transmission, 2 actually, and add some fresh fluid. The old fluid was pretty dirty. Took it for a test drive and after about 10 mins it was back to normal again. I’ll have to take it on a few more drives and see how she does. Seeing how dirty the fluid was I think I’ll just drain all of it and replace it with fresh fluid. I don’t doubt a complete rebuild is in my future, everything on this car is original and untouched. Except for the things I’ve had to replace that broke. Lol but hopefully I can keep this old girl running just a little longer.
