What do you guys do for a transaxle flush? Keep in mind my bolens was sitting in a basement for 30 years untouched, and I'm sure there was no transaxle fluid change immediately beforehand.
Normally i'd just warm it up, drain the old and in with the new but since it's been sitting so long and I don't know how fresh the fluid was that was in there I have a feeling I should do something more.
One suggestion was filling it with diesel fuel and driving around the yard a time or two before putting the new fluid in. This won't hurt it? Or should I just change the fluid out a few times in a row with a few hours engine time between? What do you folks do for one that has been sitting?
