Hi all. I have to drop the stock transmission pan on my 727 to replace a leaking pan gasket. Does anybody know how much trans fluid a stock 727 pan holds? Also can different types of transmission fluids be mixed? I have no idea what type of tranny fluid is in the transmission at this time. It's a 1969 727 trans. I bought the car 20+ yrs ago and have no idea what the previous owner used. I hope it was Dexron, but even so I see that today there are different types of that even. shruggy Please help.
