Lets revive this thread a bit,
I have the TKO600 with almost 8000 miles on it now, in two years. I now have a hell of a time getting back into 1st gear after driving a while and downshifting to a stop. It will slide right back into 1st as i'm coming to a stop (2-3 mph), but I have to keep my foot on the cutch and keep it in gear at a stop or it won't go back in from neutral if I let out the clutch in neutral and let the main shaft turn in neutral.
I thought the clutch MC and/or the Tilton internal HTOB was not releasing fully. I measured, even tried different size MCs; all the hydraulic clutch components are working correctly.
I eventually talked to Paul at Modern Driveline in Idaho, and he spent a few days with me helping diagnose it over the phone, try this and call back, try that and call back, etc. He came to the conclusion that the 5th gear "interlock"? was not resetting back to neutral. That it was a known flaw of the TKO600. There is a fix/upgrade or somesuch.
I dont have $3,000 to buy a new TKX when I spent almost as much for a TKO600 just a few years ago during my build.
So has anyone experienced this shifting back to 1st gear when stopped problem?
I first reported this back in September 2020, here:
