Semi synthetic 75W 90 for gear box

Is semi synthetic 75W 90 oil ok for my Disco TD5 manuel gearbox.

 

only use mtf or atf

 

now i dont know what spec MTF and ATF are, but the 75 w 90 was told to me by a guy who has been working on Landies for 30 years has his own garage

 

Dont do that m8 ... not for gearbox, maybe u misunderstood this one is for diffs and transfer box .. listen to jamesmartin... he knows what he's talking about ... (your guy maybe works just on series) the R380 box is very squeamish .... MTF94 or ATF dexron III

 

if i said i had my own garage and had been working a similar time would that help ,and have been reconditioning them for over 20 years atf automatic transmission fluid dexron 2 or 3 mtf94 manual transmission fluid part no stc9157 1 litre or stc9157 5 litres lr recommended both latter now recommended but will run on either ,but change yearly if long life required

 

just been on castrol site and ATF IS 75W 90 have a look castrol uk

 

Are u talking about ATF DEXRON III

 

ATF in general looking at castrol site it is 75W 90

 

No they dont look again it's Castrol Syntrans Multivehicle 75W-90 Fully Synthetic MTF

 

Cos it's a transmission fluid and the diffs and the transfer box are transmission as well... Dexron IID or III which u can put in the R380 is something else....u will not be happy with the 75w90 in the gearbox....i rest my case

 

All the major oil companies produce an MTF, Land Rover use Texaco MTF94 when it left the factory http://www.texacobaltic.eu/en/products/cars/mtf-94.html
For Amsoil oil AMSOIL - Synthetic Manual Synchromesh Transmission Fluid (MTF).

 

I cant find that bit.
All i want to know is 75w 90 ok for the box

 

Similar to MTF94 which is 75w 80.

 

Oil that works in gearboxes is not just down to the viscosities.
some stuff works well with the bearings but messes up the syncromesh function.
Some stuff works well with the syncromesh but not the bearings.
The Good stuff is good with both.
LR spent a lot of money with Texaco to come up with something that works.Why not use it - or a CLOSE equivalent if you have to.

 

you stick that crap in your box it`s gonna **** up. when it gets hot will be hell to get into gear dont do it go to landrover get the MTF94
