Indeed, but the reason may have been that they needed to cover for a piece of crap transmission. The ZF six speeds seem to be doing fine with lifetime or long interval fluid changes. Land Rover is 10 year / 150k interval and you rarely see a transmission problem on a Land Rover forum. The 722.6 is just a piece of crap by comparison and the .9 is even worse.

Interesting that Sun Valley is allowing Dexron III on 722.6s if changed every 24k miles. Those guys are no dummies. There was one post a while back from someone who had used WalMart Dexron III in a 722.6 for a couple hundred thousand miles without a problem, with regular changes.
