Question about 727 auto

[trailjeepman]

I am going to change the ATF in my 727 automatic. How much fluid should I buy and what is the best brand?

your best bet is to take it a shop that has the machine to flush out the entire system unless you have this machine. It would be alot easier and less of a headache plus it is not that exspensive even if you get them to use the semi synthetic fluid. The best fluid to use would just be Mercon 5 or 3.
