Good luck with finding the noise gremlin, Dave. I hope you get it sorted out in time for our NE nice weather coming soon.

Bob, your input in my thread is highly appreciated. You can get a TH350 or any automatic with a manual valve body that requires you to shift into the gear you want but I didn't go that route on this one. We've done some tweaking on the trans to target proper shifting behavior but almost certainly it will require further adjustment after I hit the road and see how it actually shifts up and down. Are you saying your CTS-V has a Toyota clutch? If so, I had no idea. Or are you just making the Toyota comment since I have a Toyota listed in my cars? My 6 speed car is a '95 Toyota Supra that I've had for over 12 years, bought it with barely any miles and factory fresh stock but have moded it over the years to my taste ...mostly mechanical mods other than a carbon fiber front lip to better scoop air to my radiator and intercooler, plus it incorporates two scoops for front brake ducting. The 6 sp in that car is a super heavy duty design that I've come to love but of course with over 700hp I had to go with a more serious clutch and since it's a Japanese car a couple of the best clutches are Japanese (U.S. made Tilton is too rich for me and not sure how durable it is for a lot of street use) so I have an O.S. Giken R3C triple and I really like it; I also swapped out the stock Torsen diff for a Giken Superlock (1.5 way) and that made a big difference in the stability of the car while accelerating, braking hard especially if I'm also sort of turning at the same time. Here's a couple gratuitous shots of the Supra at track days at Pocono, Watkins Glen, New Jersey Motorsports Park, and a shot of the "somewhat unique" twin turbo setup I have on it for the last few years...it works great but I have to say I have a soft spot for how this DOHC 3 liter inline 6 looks with this turbo setup.
