You leave in a 1.48:1 gear instead of a 2.48:1
Basically like having a powerglide. It softens the launch, you can ramp in alot more power. it wont make a difference for most cars, but if youre over 1000rwhp, 2.48 is really too much gearing. some people are swapping them out for 2.10's but theyre pricy.
I think I can wire the switch for 3rd and leave shifter in 2nd and launch this way.

Are you using a switch/button to force 3rd on the line to stall/spool then release to drop down to 2nd and leaving off the line in 2nd? I don't know if I read your posts correctly, but it seems that you are dropping from 3rd to 2nd to launch off the line instead of going back to 1st.

Before wiring the switch up I would just leave in 2nd gear since I could stall up higher in 2nd and have 1-2psi vs a low stall and 0psi in first. Now with my button wired up I just leave the shifter in D and hold the button and stall it up and build boost then release button and it drops back to 1st.

i wasnt able to trip it correctly with just a button, might have been because of the codes in the ECU getting upset, or it could be because its not breaking the connection, just adding a ground to the wire already setup for grounding.
i use a switch, to trigger a 5 wire relay, it disconnects the normal operating wire and throws it to ground manually, so when you come off the switch the trans works normally after you switch back, wich it needs to complete its shifts after

Talked to the guys at North Texas Converter about this before pulling the trigger. They said that for a stock trans it may or may not be the best. But for one that has been modified for a trans brake (which they say theirs and the Jakes stage II like I have) all get the modification regardless of if it gets the trans brake or not. I am not entirely sure of the inner workings of the transmission, but it is good to hear that with the transmission I have it is not in any real danger, or no more than a trans brake would put it in.
That being said mine got pretty darn hot quickly playing around with pulling against 3rd when manually commanded. It built around 7 or 8 psi very easily even with my nitto 555r tires on the car and never pushed through. I am in the process of wiring up the sloppy transbrake this week and hope, weather permitting, to get to test it at the track this weekend.
