Re: TR O/D Gearbox Oil

Simple.
The variable here is the Laycock Overdrive, which always required motor grade
oil. TR boxes work fine with motor oil in the 30-50w range (20-50w is great)
and as previously mentioned, it isn't as corrosive on syncro rings etc as
EP90 is, also doesn't break down as fast. MG trannys will work with heavier
oil than motor oil, but they seem to have tighter tolorances than the TR
trans' do, as syncros etc get very sluggish.
