th400 kickdown
th400 kickdown i have decided that i want to go with a transgo shift kit in my th400. going to keep the standard pattern instead of the reverse..this means i will have the modualtor as well.. it is to my understanding that with the transgo kit,. i can still have full auto shifts unless i put the car in 1st which would hold that gear until i shifted it and so forth. my question is if any of you guys are running this vs the full manual do you run a kickdown switch? i know some people say it is a must to run one so how do u rig it up? i have a wot switch already for my n20 so it would be kind of hairy to install another switch.. as far as the manual vb goes...i have pretty much decided to go with the above mentioned plan but with some pursation i might be tempted to go another route.. 
first off i am not going to run a t-brake..i have talked to people that have them and they say it would be hell to drive on the street all the time..like i said this is what is being told to me..not my opinion.. its the manual valvebody that i may be talked out of..is running a straight manual vb really that much more affective at the track? i mean when you can get a shift kit that can make you stndrd vb into a manual..its to my understanding its all in the pressure correct? with the manual vb it has full line pressure always vs..the shift kit using the modulator? i know you have to buy a whole new valvebody for the full manual so i guess its set up totally different,, BUT this would eliminate the whole kickdown thing...i just cant decide i kind of want to keep the auto body with manual option mainly because im told it will last longer..i dont know

John,
How do you indentify the truck v-body from the others? Also would this setup be good to 650 rwhp without killing the clutches? Most people want to put a manual v-body in one right off the bat, but i would like to keep the auto features.
