New (to me) LT230

Using a TOP TEC MTF 5100 75W oil reasoning that it was slightly thicker than MTF94, so would 'quieten the box' but no too thick as to cause the pump an issue.
Normally (before these issues i've been creating for myself, I used Dexron III, which is an ATF and slightly thinner than MTF94.
