I finally watched a transmission guy in Dayton use a bore scope on a valve body and it changed how I diagnose shifting issues
I was at a shop in Dayton helping a buddy bleed brakes when his transmission guy rolled in with a bore scope and started poking around inside a 2015 Silverado valve body. He found a tiny burr on a shift solenoid bore in about 4 minutes, something I would have chased with a pressure gauge for an hour. I went home that night and ordered a $60 USB bore scope and started using it on every hard shift complaint. Two weeks ago it caught a scored accumulator bore on a 2011 Civic that I never would have pulled the cover on just from the road test. Has anyone else started using a camera for valve body inspection or am I late to this one?

That line about chasing it with a pressure gauge for an hour really hits home. I've burned whole afternoons on a hard shift, pulling the pan twice, swapping a solenoid on a guess, and it turned out to be some little nick in a bore I couldn't even see. Hearing that a camera found it in four minutes makes me feel a bit dumb for not trying it sooner. Glad you posted this, my next hard shift complaint is getting the scope before the gauges come out.
