bought a very well built, used red neck c4 with a reverse manual valve body from a good friend. just had it installed. also had a 2.73 gear put in back along with carbon fiber clutches. when i shift it, i hear kinda like a clunk, or clank coming from either the trans, drive shaft, or rear end. dosent matter if im up or down shifting, dosent matter what rpm, speed wot, or babying it. the only time it dosent do it is when i shift from 2nd to 1st. besides that, it runs great, pulls great, ect. this may be normal for this kind of set up. have never had a manual valve body. any feedback would be much appreciated. thanks

First of all, not all manual valve bodies are programmed the same. So some will react differently from the next one.

Most of these run at full line pressure ALL THE TIME. Even when you are at idle or partial throttle. Thet's mainly why it hits the shift so hard.

that makes sense.
