Started my 4R70W swap as of tonight. Have the C4 out and getting the new trans prepped to be installed in the morning. Have a question about the starter, will the old starter from my C4 bell housing work with the new 4R70W?

Another question, and I'm sure many more to come through out the day. Has anyone installed a Casper Electronics breakout harness on the TPS of a Fitech? Do the wires have to go to a certain wire or can they go either way?

Has anyone bent the JB twin sticks to avoid cutting the tunnel. My adapter made the trans and case 1.5" longer than my C4 combo. Looks like I can bend the stick forward a bit and avoid cutting the tunnel to make it fit. Has anyone ever done this, is it advised? If so. What is the best method to bend them, heat or mo heat?

Did you have to cut the transmission shaft? If so how much did you have to trim?
