Hey guys I have a issue from trying to use my built 4l60e to my new 5.3. It feels like the torque converter is pashing against the flex plate and not letting the transmission get tight too the block. The 4L60e 4x4 i have is from a vortec 5.7 that I blew up in my s10 and got a 2002 5.3 to replace it. any help would be appreciated. I was gonna put it all in the truck today but this has stopped me for the night.

Thanks
Austin
