    C4 w/pa internals w/art carr servo&valvebody?Help please

    I have a built up c4 that has all PA internals and ART CARR servo and manual valvebody w/ transbrake. Well this is my problem. the guys I got car from said they put the A.C. valvebody in the trans and shifter great from 2/3 shift but when it was put in first the tires would lock up on it. Now there is a sylenoid looking thing that came with the valvebody and they said they didnt where to install it so they just didn't . They thought there might be a piece of garbage that got sucked up in it and that might be the problem. My question is does this sound like the valvebody does have a transbrake in it and they just didn't install the sylnd and thats why it didn't work for them??? or do you think there is something wrong with it all together??? One of the guys said they thought it did have a transbrake and the other guy said you could install a brake in it so I am lost. I'M SORRY IF THIS IS A VERY DUMB QUESTION BUT MYSELF HAVE NOT A CLUE WHEN IT COMES TO TRANSBRAKES OR TRANS. IN GENERAL BUT COULD SOMEONE HELPOUT i KNOW THERE ARE VERY SMART PEOPLE ON THIS SIGHT AND WOULD APPRECIATE SOME INSIGHT. There is a pic of sylenoid looking thing as well as a pic of the valvebody in ad#1900806. ops: Thank you for your time, Korey

    Well, I'm not that familar with C-4's, but on any other trans, the transbrake solenoid installs in place of the vacuum modulator. If it's a transbrake valvebody, and it has a vacuum modulator installed instead of the solenoid, it's probably pushing the valve and applying the transbrake. Most brakes only work in low, so the trans would work in 2nd and 3rd....I'd try installing the solenoid.

    just a guess,
