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.

i too am interested in the oil for an lt95?
I currently have 90wt in there and there does not seem to be any problems. Of course that could change if ive got the wrong stuff...

Landrover (NA), published a tech buletin ( Buletin # 007, CDS Ref L8462bu Dated 29-03-2000) detailing post WA> VINs all Range Rover, Discovery (1 and II) and Defender manual gearboxes were fitted with Texaco MTF from the assembly line.
This also details that it would benefit earlier manual transmissions, if applyed on a full trans. oil change.
My R380 dates from 97 and is appreciably easier on shift changes, just thought others might benefit from my experience.

It strikes me as odd, that Land Rover North America would issue a tech bulletin in March of 2000 on a transmission that hadn't been imported to the US since 1995 in the Defender, 1996 (and a VERY few in 1997) in the Discovery and never in a Range Rover or Discovery Series 2. If anything it may have been a regurgitation of something generated in the UK. My 110 was dealer serviced in 2001, just prior to my getting it, and the service report indicates 8 quarts Dexron ATF. I guess Miami didn't get that memo.

Redline MTL is said to be the best thing you can do for your R380.

Hmm,

Is there any data to back that? I'd be interested to see some testimonials.

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?

An LT77 is a 5 speed with internal oil pump, hence the original directive for ATF.
You want a suitable gear oil with a viscosity in the 85 or up range, but deffinately not ATF. (Use 85W-130 for the winter)

LT77 is a 5 speed tranny, if it is the later LT77S, with synchro 5th gear, I would use the MTF.
LT76 is the Series 4 Speed transmission.

LT = Leyland Transmissions
76,77,85,95 is the diameter of the mainshaft in millimeters.

Really? I thought it was the dimension between the centerline of the mainshaft and layshaft......

can't speak to the Amsoil product but I use Redline MTL in 95's, 77's and 380's.
In my personal truck (lt77s) I noticed a pronounced difference when
I put the Redline in. I have been buying it from some fellow on ebay in Pa for a bit over $8 a qt.

8 Quarts? Hopefully you got about 4.5 quarts in a 'to-go' box. If I'm not mistaken, the R-380 takes about 2.7 litres (4.7 pints) and the LT-77 takes even less at 2.2 litres (3.9 pints).

I just ordered a gallon of Redline MTF in hopes of eliminating the dreaded 2nd-gear grind. I have tried 80W-90 and then ATF. Both with the same result. I'll try to follow up with the results.

When I took delivery of my D-90 the gearbox was empty. :eek:

Les thanks for that info about the tranny classifications, learn something new everyday.

I'm not surprised you have difficulty using 90 weight, since the internal oil pump in an R-380 can't even pump it.
