Here's the deal.... The makers of Auto Transmissions (and for some reason even in our application) design them so that the shifts are smooth and as "imperceptible" as possible. To do this they actually have, during the shift, both gears (clutch packs) engaged at the same time. Handing the change in ratio over with as little disturbance as they can.
What this is doing though, is creating a Bunch of friction and friction = heat & wear. So, the modified VB is designed to eliminate some of that, the transition is firmer with less "mush". It's a subtle difference though, not as dramatic as you might think. You won't notice a Nigh & Day difference, not gonna chirp shifts or anything. Just know it's Much better for the life of the transmission.
At 150K though, I donno if it's gonna do much for yours. At this point you've got most of that wear already...
