"Constant pressure IS NOT the solution for sure. It requires the pump to work itself 100% of the time, increasing side load to the pump gears and pump bushing...and also increases pressure on all trans components as seal...rings mainly...they are subject to the side load of all that pressure for no reason. They will wear out the stator or the rings, or both in terms of constant use such as a daily driver. When these components fail is totally unknown.
When you pick up a penny on the sidewalk, to you flex your muscle and pinch the living hell out of it just to lift it and put it in your pocket? No you use just the right amount of force/effort it takes to move it from A to B. Or does your heart pound @ 200 beat per second all day to maintain life...nope...just what it has to.
Well with constant pressure you are asking the trans to flex its muscle and beat its heart as hard it can 100% of the time."
My car sees 15k miles+/year, so I don't think I want to go that route. Besides, there are probably millions of AODs on the road in variable pressure factory applications. I think the fear of the TV is forum-bred hyperbole to some extent. There are a lot of Bubbas out there working on these things and they're not killing that many AODs. If the installation is right and a little attention paid to maintenance of the cable, I just don't see any major issues.
