I've used Shaefers in the past after reviews on Bobsistheoilguy forums and have been VERY happy with it... But what do I put in my 727? The car has about 130K miles on it and I dont know if the tranny has ever been serviced, but the fluid has NO burnt smell and is a good color of red.

Type F, Dextron, Mercon etc all have basically the same lubricating properties but have different friction modifiers. The friction modifiers cause the clutches to slip a little on engagement and lessen harsh shifts. Type F has less friction modifiers and therefore shifts are firmer. Ford designed their transmissions around that fluid that is why a Ford with Type F shift like a Dodge with Dextron, but a Dodge with type F shifts firmer. Be cautious of the newer fuids because they are loaded with extra friction modifiers and are very slippery. The lockup convertors are very harsh on lockup if you don't have them. Some of the newer transmissions require CVT fluids and such. For older stuff like ours I like type F. It is as close to the Dextron II that they were designed for as you will get these days. Often mix it with the current flavor of Dextron. My
