I had a T-45 and that crossmember bolted up fine. Yours might also. But I had to move it up about 5" on the frame rails due to different tailshaft housing mounting locations.
Just for the record, I sold the car and on the first drive for the new owner he broke the intermediate shaft on the street tune putting 780 rwhp down. just doing some highway pulls. And Darrin wouldn't answer his phone, which doesn't surprise me since he wouldn't answer for me the last time I tried to call him either.
Darrin can be hard to get a hold of. He took care of me after the sale and shipped out a new complete tailshaft housing at no charge when I destroyed the seal.
Obviously I have no idea why the intermediate shaft broke in that trans. From what I understand though, shifting into O/D under WOT can break that shaft. I'm not saying that's what he did but it certainly could be a possibility.
I spoke with Darrin a couple of weeks ago and he said he has a lot of things going on now and he doesn't have time to work on transmissions right now. Put me in touch w Chris @ CircleD for my converter. Think he has moved on with his other business.
How do I correct m speedometer??? I'm in binary editor right now but can't figure out what needs to be changed. It's a 4r75w with 315/35/17 et streets ad 4.10 gears
