Ok here is my problem, I bought a truck with a 6.0 swap, the trans was trash so bought a built 1. I'm not getting any fluid flow. So I talkd to circle d converters n he said it could be I'm using the wrong parts to adapt 1 or the othe. IE moter/trans. So I need to fig out wat they r lol. I know the motor is a 2000 6.0. Cast iron heads, but no idea wat flex plate is on it. I used the 1 that was on it. N he says it could be diff depending on trans it came with frm gm. Second need to know wat 4l60e I'm using. I didn know there were 2 diff 1s. But he said it matters so I can see if the right converter is used. So any help on this is a huge help. My project is on hold.
