maybe related. but it won't shift from 1 at all until warm up. then, even after driving all day, often, but not always, it will skip 2 and go directly from 1 to 3, which would not be too bad, but it goes to very high rpms before it does it. other times it goes 1, 2, 3 exactly as it should. very curious intermittant problem. has my good mechanic stumpted, too.
