Re: shifting issue with 3GMD/KM3-A
Just a quick follow-up, but my shifting problem may have just been dirty oil. It had plenty of oil when I checked this weekend, but it looked embarrassingly old - sort of milky cast to it as well. With fresh oil, it did hang up once, near beginning, and then seemed to be good the rest of the weekend, with couple of motoring legs that were long enough to have triggered the fault before. I will do another oil change next visit to be sure all of the old stuff is well gone.
Can anyone confirm the correct way to use the dipstick in the KM tranny? I believe you unscrew it , wipe, then re-insert it without screwing it down, to get the reading. If you need to screw it down, then the reading will be quite a bit higher on the stick. I have had various small gas engines with similar dip-sticks, and have seen that some manufacturers say to screw theirs down, others say to not screw it down.
Finally, what is the usual recommendation as to tranny oil changing frequency? (10-30 CC oil in this case).
