The gearbox and overdrive call for 30 wt oil. The MTL is a 75W/80 wt
GL4 gear oil that has a SAE viscosity of 10/ 30 wt engine oils.
The MT 90 is a 75W90 wt GL4 gear oil and the viscosity is that of a
90wt gear oil which is to heavy for the Healey gearbox.
We have been using this in the transmissions for about a year with
not problems.
