thanks for advice

MTF94 as recommended by LR for use in R380 gearbox

although atf would do nicely and was recommended for r380 to begin with ,i rebuild a lot and atf will protect your box as much as any oil,the same lubrication or lack of it are still as evident with mtf

I second that, use MTF94 in the gearbox. Carlube do one for a reasonable price, and Millers XSS 10w40 also meets the correct spec.

HTH,

Yep, MTF94 is available at a decent price, it's recommended by Land Rover, and most of us use it... You may find it's actually cheaper from your local LR dealer (I did).

The Difflock stuff is supposed to be better.

As above, MTF...wouldn't do it myself.

im not saying mtf isnt good just that for wear atf is as good and often with either,you do tend to find boxes often dirtier inside with mtf than atf presumably atf has more detergent

This is the MTF before Difflock put there label on the bottle and can be used instead of MTF94 which is Texaco
AMSOIL - Synthetic Manual Synchromesh Transmission Fluid (MTF)

My local motor factor sold me comma dexron 2 and told me it was the right stuff. Beginning to wonder if it is, any advice please ?

Tiz ATF

I put ATF in mine on first service, it had syrup in there before! The gear change was much easier, second service I put mtf in and it was better still, I'm sticking with mtf now (or the shell equivalent anyway)

The change quality of the R380 gearbox is adversely affected by the poor of operation of the synchros, as I understand it.


Using ATF gives too much slip so the synchros don't work correctly, whereas MTF 94 and EVO1 have friction modifiers to correct this.

not true synchro wear is still as evident as ever was with atf the main problem is baulk ring hasnt got dog teeth all the way around it unlike most baulk rings,ive stripped and checked thousands and its the outer teeth thatwear first and dirty oil thru lack of servicing that takes in surface out

Yeah as above, its frequency of changing rather than the exact type of oil, so long as its more/less within the viscosity requirement of the gears and synchros. So, when you use your very expensive synthetic (typically about 3x the price) are you tempted to leave it in 3x longer, or are you going to change it every year/12,000 miles like the service interval suggests?

Well personally I give my motors the best I can afford and am repaid with reliability.

I use synthetic transmission oils which cost about double the price of mineral oils and I change them every 10,000kms.

That's the best advice anyone can give
