Transgo VB Upgrade NOT for 5AT Daily Drivers
I have painfully come to realize that with the Tansgo valve body upgrade, you will never get rid of the 2-3rd hard shift. I had the Transgo kit installed with my turbos and the 2-3rd shift got harder and harder over time. It got to where it felt like someone was rear-ending me when it shifted. After about 30k miles, it was so bad, I had to get my entire transmission rebuilt. $6,000 later, I got my G back, and I can still feel the 2-3rd hard shift. The problem was not fixed, just masked. I am at the point where I probably have to buy a new factory valve body just to get the transmission to shift normal. I would NOT recommend a Transgo valve body upgrade for a daily driver. I spoke to Transgo and they said they were aware of the problem and there was no fix. They have terrible customer service and had no interest in helping me. If anyone has ever been through this nightmare and knows a solution, I would love to hear it.

I'm sorry you're going through this. Honestly though, I think you had either installation error or incorrect AT fluid levels. I've daily driven my supercharged coupe with transgo kit for over 15k miles and have not had any problems with the kit. You get hard shifts when you drive aggressively, and slightly more noticeable than stock shifts when you drive normal.

I've been reading FI forums back and forth and it just seems to be a mix of people who only drive in manual-matic and others leaving it in drive. No real hard evidence has been provided that leaving it in drive will hinder your tranny though, so I'm just trying to figure what the issue is before I start piecing together my Vortech.

Other then the obvious of being able to somewhat control your car's shifting when you're a boosted 5AT, does it hinder your tranny in anyway to just leave it in drive?

As far as mechanical issues go, the 2nd-3rd shift gets harder and harder with time, and I had to get my transmission rebuilt within 30k miles. I suspect if I do not buy a new VB (another $1000), I will be rebuilding my transmission again in the near future...but I am not sure how the new stock VB will interact with the built transmission??? I may need to check out a different VB upgrade. I guess the only alternate is a Stillen VB. Looks like I will end up with a $10k transmission when all is said and done. Maybe I should have bought a GT-R.
