If I remember correctly I used to use ATF in my Talbot Torqueflite Auto Box. I actually managed to rebuild that one but not recomended. I digress. Thanks for that interesting bit of info. Why does ATF work with a leak when the normal fluid doesn't? I haven't bought the car yet so is there a lot of work in converting to use ATF? Sorry to keep asking but I am trying to understand the problem as well as look for a solution.
