5AT Upgrades for boost.

Did adding the Edge Racing TC drastically improve power performance?

Now the valve body... that rocks! Very solid and quick shifts.

What brand of a valve body did you go with?

Coach, are you running an aftermarket radiator? Or is your tranny cooler an additional auxilary cooler?

I asked Thomas at SGP a simple pre-sales question. If I floored the car in full auto mode, would the SGP VB ever miss a shift? He said no. Can you vouch for that?
Also, how hard are the upshifts and downshifts when you are cruising at low throttle?
Thanks again!

Under normal driving the shifts are strong but not teeth chipping hard. It does take a little bit of getting used to. Trust me though, it is all worth it.

I hope there is not a long wait or too long of a downtime for this part from SGP.

I've never seen that number (325 rwhp) being referenced as a safe "stopping point" of the stock transmission. I've also never heard solid answers to what the VB and TC will support, but I highly doubt it'll raise from "shouldn't go past 325 rwhp" all the way to "500 rwhp."
In all reality, who has destroyed their 5AT, built or not, from too much torque?
Correct me if I'm wrong, but isn't torque the killer of the tranny?
I know of a 507 rwhp tc+vb upgraded 5AT... what other numbers have you heard of on the 5AT? The 507 is runnin fine so far (VRT JWT TT
)

Is the SFR tranny giving you trouble at high hp/tq levels? Is that the basis for the recommendation for a GM tranny upgrade beyond 500? I thought that thing was designed for 800-1000 hp...
I have an upgraded TC from Edge Racing and also an upgraded VB from GTM, they did the install on both along with a oil cooler and tranny cooler.
When I left the car was putting down 410rwhp and I had no issues, right now the car is back with them with a new engine ( lower compression) and a few other things, we shall see what the setup can handle now.
Before the APS TT, I had a Voretch with 400rwhp and I was running on the stock setup for over a year with no issues. Soon as I went to the TT I started to have shifting issues which maybe due to the more trq I had acquired.

OT..you going to the Bradenton event on 9/30? My car will be a good example of what this tranny can handle.
I don't know if anyone has told you this yet but its not really horsepower that kills that auto tranny it is the torque. It is dangerous to go over 400rwtq in the auto tranny. This is also a very interesting thread but i have one question someone mentioned a auto that has 517rwhp im figuring this is TT if so those torque numbers should be over 400 so how is it making this type of power without slipping with just a vb and tranny cooler.
