MTF

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.

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?

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)

thanks, im going to be changing all the fluids one of these weekends just makin sure im using the right stuff

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.

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.

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.

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