I have a 2002 GL1800 with 40k miles, it runs great except for one aggrivating thing. When shifting from 2nd to 3rd it will not lock into third gear. if i shift at very low speeds it will go in ok. but if the rpm or speed is high it will not shift into 3rd gear. Any ideas what the problem is, the Honda store has checked the hydaulics for air and bled the system, still has the same problem....Thx....britrod...
