The issue really came on after the SC install, so I suspected bushings, it was nominally good before that. The SC definitely puts more movement/hysteresis in the system. For now, I just sacrifice the TOB and hold the clutch in while I'm in first until I get this resolved. New clutch and TOB is on 5K, I'm safe there. New motul gear fluid put in same time as clutch.

I'll get some more bushing work before I replace the trans, thanks to PulsarBeerz. I'll try evert bushing available before I put a new trans in.

I just had Torque Solution motor mounts, and Whiteline KDT922, KDT925 and KDT923 bushing kits installed today. Needed them for SC upgrade, hysteresis was excessive on any spirited launch to the point of bucking, or wheel hop. Laying into it hard you could definitely feel the excessive deflection in the system that if you didn't manage correctly, it lost its smooth transition to and from power.. That's gone now, feels really good and the transition to and from power hysteresis is greatly minimized. You can still feel the bushings doing their thing, but they're all much stiffer now as they should be.

I blew a pressure hose off leaving as the techs must have loosened the connection for motor mount install and forgot it upon reassembly. The clamp not blown was loose to the point I could loosen it by hand, so I know they had to have loosened them. I had 4k miles from same shop on the SC install with no issues. Thankfully, I leaned in hard out of the shop to find out early. Walked back, got a screwdriver, fixed in two minutes, drove back and returned the screwdriver. I'll lean on that shop for some perks in the future. And teach the owner to lean on the car harder when testing.

Shift issue persists, but I didn't expect that to be resolved as I was after another issue that I figure caused this one to begin with. But I can see how it is party to the issue and likely moved or damaged othher bushings as well. Or, at m mileage, its just finally worn out.

Back to the parts boards, thanks for the guidance and experience on these matters.
