MTF

[Les Parker]

Changed the transmission oil in the DEf 90 recently to Amsoil MTF.
What a difference !! Selects very well and NO notches on 2nd gear, as before with ATF.

Is ATF for auto transmission only or can I use MTF on my 97 D90, is your D90 automatic or stick ?

Jorge,

My 90 is 5 speed manual, MTF is for Manual trans. ATF is for automatics.
Up to now I have used ATF on my 5 speeds also. Now, it is time to rethink this strategy.

LT77 manual gearboxes should have ATF Dexron II oil.

Land Rover always specified using ATF in the LT77 and R380 5 speed manual gearboxes, as well as always using it in all the auto boxes. Amsoil is one a few that have recently formulated a gearbox oil specifically for manual transmissions, and the point Les is making is that using it improved his shifting. Land Rover hasn't come out with any directive telling owners of LT77 and R380 gearboxes to use an MTF formulation as yet.
My only concern would be the internal oil pump on these two gearboxes. Unlike most conventional manual gearboxes that get lubed by splash, the two Land Rover boxes have a forced oil circulation by way of an internal oil pump.

what oil should I run in my Lt95?

Land Rover always specified using ATF in the LT77 and R380 5 speed manual gearboxes,.

Is the Lt77 the transmission I have in my 72 NAS series III 88? Its a four speed, should i be putting ATF in there vs. 90wt?
