I would have had a Viper 6 speed with a known 3/4 shift problem and a box/bag of parts and a face... Yes, you look at that scenario as someone who can diagnose the problem, determine the parts required to fix it and anything else you may have found, source the parts at a reasonable price, and fix it and put it all together and have it work. Like I do with medical equipment and audio/video/CCTV and home theater systems. There's other things/stuff I know how to do, or research and figure out, and I believe manual transmission diagnosis and repair is probably something that would come easy to me, BUT While I'm doing all that, I'm not doing my day job, and my ONE man business doesn't run unless this ONE man is working. Sure, there's things I either want to or have to do with my car and the GTO myself, but if I'm busy and can make what I spend in the same amount of time, well as long as the mechanic is competent, we both do what we do well, and I come out even, and know the mechanic work is done right and all I have to do is write the check and turn the key... From the guy w/a real V-code but not drivetrain matching #s, who has had subframe connectors, torque boxes, and sliders welded in/on, replaced his correct V-code K-member and front suspension and bench seat and SOLD them both, and now that AMD is making BEAUTIFUL factory appearing inside wheelwells for wider tires and there's a leafspring relocation kit and I have the desire for REALLY wide rear wheels and tires..... Even with ALL of that, I am EXTREMELY happy that the 855 didn't require ANY cutting, pounding, patching, or welding to install the Passon 5 speed!! I'm especially glad that I didn't have to cut up the transmission crossmember!! Now, if anything on the GTO has to have any of that kind of invasive, basically non-reversible surgery done to it to make the TKO600 look "factory" from inside the vehicle, so be it! Why? Because it's a rather common GTO 38o 4bbl car, but it is built and presented as a Royal Bobcat Tribute car, so it's already had a significant departure away from how "it was born" including the AWESOME Quick Performance 9" rear axle assembly, UMI rear suspension arms, and the separate shock/spring array is being replaced with a single point coilover rear suspension design. It's going to be SO MUCH BETTER than how it was, and I was VERY happy when I grenaded the POS open factory Pontiac rear axle assembly at the track one day a few years ago. The 9" setup was already "planned" but it got moved to the top of "the list" and got it done! So I know that dichotomy may not make sense, but it does to me, and THAT is what really matters.
