Hi Jack, In my searching for old literature on toyota campers I came
across a Sunrader motorhome and slide in camper owners manual on a
bookstore web site, I don't know what years it covers or anything, in
fact I just mailed the check off yesterday so when it gets here I'll
let you know what it is and what it covers. Your oil consumption
might be the valve guide seals letting enough past to show use but
not smoke, just a guess, Your probably on the right track with the
tranny problem, with all the computer controlled electronics it could
be thermal or some sensor or who knows what. Hope you figure it out.
