I recently picked up my 04 Lightning, and am wondering if this truck will benefit in the same way my old 7.3L Diesels did, by installing a shift kit in the 4R100 tranny. Lots of wasted torque, as I can feel. ' One other question. I have an 03 Cobra, too. I like that 6sp tremec, and am wondering if there is any chance I can mate a tremec to the Lightning's 5.4. Thanks in advance. Looking for suggestions, not smart a$$ replies, as is often the case on this forum.
