I'll try and check mine in the next couple days Mike, but I'm pretty sure the trans mount bolt is almost at the end of the slot away from the cross tube.
Thanks guys, this was perfect.
I have been getting more inquiries on 4L80 trans, which is a few inches longer then the 700R4. So I'm looking at making it adjustable to slide rearward to fit longer trans. The T400 is also longer. I know the lengths just needed to make sure where I'm at now.
Why they want to use the 4L80 is beyond me, I've always felt the 700 is the way to go, but then I also get inquiries for the Th400
