Oooh man! 
If you've got an automagic GET THIS MOD first before anything else (after an OSCAI) including a y-pipe, b-pipe, udp, rsw, fstb ect. I knew the auto tranny shifted poorly but I didn't realize how bad it really is until now.
I live in Austin which is about a 2 1/2 hour drive from where Don is in Houston so, to minimize downtime for my max, I took the VB out in my garage Saturday morning (after letting the car cool down overnight Friday night) and drove to Houston in another car, went over to Don's to get the VB done and drove back to Austin Saturday evening and put it in Saturday night. Don is a very cool guy and a genuine car and Maxima enthusiast at heart. I don't know if I could have gotten a more carefully done mod anywhere.
Here's how the tranny used to shift without this mod:
vrrooom ......... s h i f f f f t t t t.......... (now you've got to push the engine more since you lost so much time and momentum while the tranny was busy shifting from 1 to 2, sooo) VRRRROOOMMM . . . . . . . . s s h i f f f ff t t tt . . . . . . . VVVRRROOOOMMMM (now you've really got to push it even more - you get the idea).
Here's how it shifts with this mod: vrooom.shift.vrooom.shift.vroom.shift. It shifts like clockwork. It's a night and day difference. The harder you drive the quicker and more surely it shifts. I haven't been able to wipe the big grin of my face all day! My first thought was this is how the tranny should shift in STOCK form - I don't know why Nissan doesn't improve this on the automagics.
Thanks again Don!

I don't live in Texas, so I'd have to ship mine from VA, hence taking my one form of transportation out of action for a while. BUT, my ship is going underway from Aug 1-21, so now I have an excuse to get this done much sooner...I have a couple questions though-I have no idea what a valve body looks like or how big it is, so how much would it be to ship? Can any retard with the right tools take it off? Thanks!

First I'm heading of this "Don's Mod." Don must be an impressive guy. Since I live in PA and no where NEAR Houston, can we get some info from Don as to what he's doing to the VB so maybe I can get a good tranny guy near me to work on it?
Yes, if I have a good tranny guy, he should be able to do his own work and should know exactly what to take care of for me, but just curious to see what research I can come up with.

That is strange everyone says their Max shifts slowly and slushy. My Max shifts very firmly and quick. I actually think it shifts too strong sometimes. Would I benefit from Don's upgrade if my tranny already shifts very quick and firm?

The removal and install is pretty easy, you've got to prepare and plan well before starting it though. It pretty messy though. But it's way worth it!! By the way it also downshifts just as crisply when you need it!

ncm00max: I was kinda hesitant about removing it at first. You just have to plan it very well and make sure you have a clean work area and keep everything you unscrew very clean when putting it all in (that's what all the break cleaner is for). But it's really just a matter of uncrewing a bunch of bolts and keeping exact track of where each one goes and making sure you have them torqued correctly when putting them back. The VB weights about 10 lbs and you probably will need a "file" size cardboard box to ship it.
marky320: If you need to replace the solenoid and TCM under warranty, in other words if you car is affected by the TSM then I'd definitely take care of it. The VB mod is simply a mod for a tranny in good working order, it's not really a replacement for issues you may need to take care of under warranty.
Max_5gen: sometimes it did, but it shifts like nobodies business now!
