I'm contemplating an LS swap, using a Tremec TKO 5 speed. I would like to go with the Holley mounts, but they don't list on their site specifically for that combination. They list for LS with T56 or T6060, but not a 5 speed. I called their tech line, and spoke with one of the folks there. He told me that Holley hasn't done an LS swap buildup with a 5 speed yet, that's why they don't list parts for it. He suggested using the mounting kit for a 4L60E, then positioning the crossmember in the spot where the TKO will fit, and mounting it to the frame in that spot. Anyone here have any experience with this?
