I am putting billet parts and checking everything out in my buddies trans. It was already built by a fairly local shop. The truck is getting a decent build and will be around the 900-1,000hp mark. I usually modify the stock valve for no converter knock down. This one has a trans go valve in it and unfortunately I don’t have any spare early 5 speed valves. Is it possible for me to tig weld up the hole on the end and the hole on the body and grind the valve just like you would a factory one? Or is there a better method, or is it just best to leave it and still let it knock it down some?
