I want to change the 55 year old oil in my T-10 in my 63 Buick LeSabre. So what do I use I have been all over the net asking all the experts and I am so confused. I think I may have to go to the wrecking yard and start to drain the oil from all the old trannies. That may the only solution. I know about the GL-4 business, but what I find is synthetic. Maybe just a big rubber band. What the heck is the correct answer??????
