Thanks ya'll - we were able to find the cross-reference number and found the part in one of our local auto parts store! We also added the shift kit as suggested! And, I think I did add our info on the coach, etc in our profile....but, still kinda new at this and might have missed something.
Again, thank you all for your input and advice - hoping to be back in the running on Tuesday...as far as the tranny is concerned. Then Lucy goes to another mechanic for radiator flushing and other minor fixes! ? Become full-timers on Oct 1 -- we need time to load her up!!
