DiscoStu Posted May 17, 2011 Share Posted May 17, 2011 Hi all, Disappointingly, I wanted to ask a question about my gearbox! When cold, warm, running about, off roading etc my gearbox is fine if a little notchy on 2nd - no news there. It's a recently new to me truck, 300Tdi 1995. After motorway journeys the gear change really tightens up - not unusable but its quite tight. I noticed after a recent run to a trial (40 miles) so decided to change all the fluids. Done G & T box and both diffs. I used ep 80-90 in the T box and Good quality ATF in the G box. Thinking that all would be solved - especially after seeing the trickle of carp that came out of the gearbox - I did another run to another trial. No change, box still stiff when coming off the motorway and stays stiff for a good while until, I assume, it cools down. Does anyone know what causes this? Is it something I can rectify? Stu.

monkeyb0y Posted May 18, 2011 Share Posted May 18, 2011 The other thread r380 gear selections is worth keeping an eye on as it sounds similar...I take it yours is an auto as you put atf in as opposed to mtf for manual...I used mtf and put in 2 molyslips from halfords....it helped....

Retroanaconda Posted May 18, 2011 Share Posted May 18, 2011 Putting the right fluid in might help R380 boxes require MTF94, it's the earlier LT77s which take ATF. Land Rover changed the spec at some point during production. Quote Link to comment Share on other sites More sharing options...
DiscoStu Posted May 18, 2011 Author Share Posted May 18, 2011 Thanks for that sage advice It's a manual R380 (hence the stiff gearchange) - yes new fangled folk use MTF but historically its been ATF - it even says it in the Haynes book of lies. Do you think swithcing to £40 worth of snazzy oil will do the trick? Stu. Quote Link to comment Share on other sites More sharing options...
monkeyb0y Posted May 18, 2011 Share Posted May 18, 2011 It's cheapest potential fix I think tbh....I would put molyslip in as well.. Even an easy life gearbox seems to play up 100k into its life...considering they can pull ridiculous loads, its disappointing in my opinion..

JimAttrill Posted May 19, 2011 Share Posted May 19, 2011 It's a manual R380 (hence the stiff gearchange) - yes new fangled folk use MTF but historically its been ATF - it even says it in the Haynes book of lies. It also says so in the genuine bedouin LR manual. But LR changed their minds in 1996 in favour of MTF94. It is no coincidence that the Freeloader came out then and the oil was the spec for its gearbox. I managed to get a 20l drum but used it all up. So then I switched to Redline MTL which is a fully synthetic. Expensive, but gives a wonderful gearchange. Quote Link to comment Share on other sites More sharing options...
