Defender 1996 r380 HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!

Hi all
Just got my first Landrover and think i should give her a little bit of TLC before i let her teach me how to drive off road.
I am going to service her and am looking into changing the oil in the gear box transmission and everything else usual on a service.

I have had a look under and from what i can see i am missing what at first looked like a drain hole on the 5th gear extension of the gear box.
After sever hours of sh***ing myself thinking i have been driving with no oil in the gear box, i have come across loads of information and just need someone to conform i am correct

on the lt77 the hole was used for an oil filter and a second drain hole for the oil. But in the r380 this is not longer used and left open to allow oil leackage to drain out without causing problems to the clutch or something like that and should only be capped of going wading (deep water/ mud)

Is this correct or am i very mistaken

Also several places say that you need a torx 55 to undo the filler bolt is this correct as the only ones i can find seam to be large star key screw divers shoved into a 1/2 drive socket and the nut seams to be a square nut on it

Help please

I think the drain hole you are referring to is in fact the flywheel drain/wading hole and is at least 18 inchs away from the lt77 oil filter assy.
I think you need a pic for an accurate answer.
Where is your reverse gear? to the right and back, or to the left and forwards?

This may help http://www.landyzone.co.uk/lz/f7/gearbox-leak-drain-breather-holes-133708.html

on ali housing rear of main casing on lt77 is 15/16 24mm bung which holds filter with drain bung drivers side on main casing,r380 has no accessible filter but drain is in same place on front of gear box main casing is bell housing ,in front of that is flywheel housing with hole for timing pin and bung for wading,they do normally have torx bit but may have been changed for 1/2 square headed bung like lt77 for ease in past

Thanks for help, reverse is under 5th so i deffentlly have the r380. I have found the filler and drain holes on it but when laying underneath the landie (under drivers seat) there is another bit if the gear box just behine the engine sump, and the hold is in the middle of this i will walk on up there and take a pic in a minuit if that will help.

Ok pics to conform
this is the hole that seams to have no plug in it

and sorted the torx 55 problem was looking at something different it is torx 55!!!!
one down one to go

pics

Thats where the wading plug goes, Even the LT77 didnt have this pluged all the time, just a lot of nuggets never take them out

Cheers many thanks i can rest easy now and thanks everyone else for your help to

I have one more question
Im thinking of changing the dif oil at the same time just to be sure its ok and they look to me like they have a half inch square bung in them like the back if a 1/2 inch drive socket.

Is there a special tool needed or can i just shove the rench in the hole and on you go???
kev

no special tool just 1/2 rachette etc

James your a star
from what i can see same oil as transmision is that right

nearly all sorted now just need to get the oils and that will start a whole new ball game i guess
any info would be helpful

diffs are same as transferbox ,gearbox atf dexron 2 or 3 or mtf

OK diffs and transfer box are ep 90, main gearbox is auto trans fluid check your year for the correct specification DO not use anything else. Or use difflock fully synthetic, i gave it a try cos my box was touchy about going in to second when cold after having that stuff in my box for 2 years now it is still doing the trick

you should change it 2 years is a bit long not for oils ability to still work but the contamination that goes around gears ,baulk rings brgs etc,use better oil but still change it ,i still rebuild plenty with posh oil and ****ed parts because of the stuff going round with oil,

nice one mate

and i take it engine oil cheap full mineral oil and change it at service intervals is what i have been sujusted or should i go for something better
and amoutns i am unsure of
engine is about 6.7l
gear box is like 2.5l what about the transpher box and difs???

as for the main gear box auto trans fluid or difflock fully syth which is better

(2.78) 3 litres gear box t/box !1.5 each diff,engine oil fine gear box synthetic can be better especially with gear change but still change it yearly ,but others would do fine and wont shorten boxes life

ok will someone please check for me i know im a spud
think these will be correct and enough for engin and gear box can seam to fine anything for transpher box or diffs as yet
4x4 Store

the difflock evoloution1 fully synthetic gear oil can extend service intervals to 48 K miles.
Mines has done less than 10K in the last two years. I run standard oils in my diffs and tranny box. I change the diff oil every six months when changing the engine oil and i only use castrol GTX for the engine, The transfer box gets changed every year

you strip as many boxes as i have and you will change your mind ,the oil might last that long but it will be heavily contaminated with condensation gear and brg particles .,case filings etc in less than 3 litres of oil ,they also put special seals in alot of boxes too to keep the **** from the brgs with extended service intervals but that dosent help gears ,synchros etc,the longer service intervals now recommended arent given as the best way to gie box long life but to reduce what they have to do /time in servicing,lr dont want cars on road past 6 years not when you make a living selling new

ok think im getting it now

so am i right in saying
difflock eveloution 1 in the main gear box
sp90 of difflock eveloution 2 in the transpher and diffs
and castrol gxt 10w-40 for the engine

this is doing my head in may book it into the garage and let them do it, it will probably end up there if im playing with it
but if you dont try you dont learn

also is there anything else i should be look at on the service i know to look at the breaks as well but is there anything else??????????????????

oh really appricate all the help i know im being a pain in the ass lol
