" From: farna@xxxxxxx " " It depends on " the "smarts" of the transmission some too. I have no problem pulling a " 3,500 pound trailer with my Volvo 960 (2.9L DOHC in-line six), and I " left it in OD. It didn't run in OD more than half the time -- it would " quickly drop to 3rd whenever there was much strain on the drivetrain, " not just a drop in speed. The older, non-computer OD trannys don't do " as well. The computer monitors engine rpm as well as road speed and " reacts faster. The AW4 does almost as well, but the Volvo drops out of " OD a lot quicker than any Jeep I've driven -- but that could be " programming due to engine size (Jeep 4.0L). you do know the volvo's auto -is- an aw4? maybe they make their own controller for it - it sure sounds like it behaves better! ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought
