Thanks guys. that's what I was worried about. Trans is a 3 speed, no overdrive. don't know the gear ratio. Now to find someone to check it without costing 175.00. the motorhome is 22' and i get 10mph per gallon. Gonna have to find out how to hook up a different tach to check the other one.
as far as shifting, it revs pretty high, but not excessively, between 1st and 2nd. then between 2 and 3 you cant tell it shifted at all. Never really settles down between gears....
