Jyodaiam Posted September 23, 2013 Share Posted September 23, 2013 I have recently bought a 110 defender 1995 after my old one (identical year and body) started to need more welding on the chassis. Having driven it in now the gear box needs attention: Can't change down from 5th into 4th; I have to go into 3rd then into 5th Can't engage the transfer box; I could when I test drove it The gearbox is now starting to make wizzing noise I visited a local garage who specialise in gearboxes and he had a discovery gear/transfer box same year on the shelves already to go. Could I ask for advise on replacing the gear/transfer box given that it is from a discovery (I believe it is a r380); I have been told that they are better runners on the road but a bit high for off road???

Retroanaconda Posted September 23, 2013 Share Posted September 23, 2013 A Discovery R380 gearbox is not a straight swap for the R380 gearbox in your Defender 110. The shifter arrangement etc. is different. As for ratios it depends what sort of driving your doing. Off road won't be affected as the ratio in low range is the same for both transfer boxes, only high range is different from Defender to Disco.

Jyodaiam Posted September 23, 2013 Author Share Posted September 23, 2013 Mmm. We travel from spring to the end of summer on the roads and then I'm back in Yorkshire for the rest working on the moors, so a bit of both usage wise. However the travelling costs more fuel so a suitable gear box would benefit my pocket more in the long run. How does this fit with the discovery box? Is it costly to fit? Gearboxes haven't needed my attention as yet so a bit to learn, but we never stop learning. As much advice as I can get, as this landy is staying with me for a long time and want to get it right now at the start. Many thanks Quote Link to comment Share on other sites More sharing options...
nobber Posted September 23, 2013 Share Posted September 23, 2013 How much is he charging you for the gearbox? Quote Link to comment Share on other sites More sharing options...
Jyodaiam Posted September 24, 2013 Author Share Posted September 24, 2013 £400 and £200 for fitting 6mth warranty Quote Link to comment Share on other sites More sharing options...
nobber Posted September 24, 2013 Share Posted September 24, 2013 £400 and £200 for fitting 6mth warranty Why not give Ashcroft Transmissions a call, you will get the correct box that will fit properly for around the same price. They recondition gear and transfer boxes and have a very good reputation for good quality. Second hand is always a gamble and at that kind of money if it were me I would rather buy a reconditioned unit. http://www.ashcroft-transmissions.co.uk/ Quote Link to comment Share on other sites More sharing options...
Jyodaiam Posted September 24, 2013 Author Share Posted September 24, 2013 Thanks for the advice. The unit i got a quote for was for a reconditioned. Trouble was it was for a discovery box and I'm unsure what needs to be done for it to fit. Do you know how the defender and discovery r380's differ?

Aragorn Posted September 24, 2013 Share Posted September 24, 2013 you'd need to either strip the box down and swap the selector shaft for a defender one, or buy an adaptor piece to allow you to fit the defender selector to the discovery box. You might as well just buy the correct box from the start, or have the existing one repaired. Quote Link to comment Share on other sites More sharing options...
nobber Posted September 24, 2013 Share Posted September 24, 2013 Isnt the discovery box longer? I always thought discovery boxes had a longer main shaft. Quote Link to comment Share on other sites More sharing options...
Aragorn Posted September 24, 2013 Share Posted September 24, 2013 not compared with a 300tdi defender box no. Quote Link to comment Share on other sites More sharing options...
Jyodaiam Posted September 24, 2013 Author Share Posted September 24, 2013 Was is the difference in drive and running between the defender and discovery box? Quote Link to comment Share on other sites More sharing options...
Mo Murphy Posted September 28, 2013 Share Posted September 28, 2013 Don't muck about trying to get the wrong gearbox to fit. Fit the correct gearbox and do the job properly otherwise you'll only regret it later. Mo Quote Link to comment Share on other sites More sharing options...
reb78 Posted September 28, 2013 Share Posted September 28, 2013 I'd just go for a late defender lt77. Perfectly good boxes with uprated components over the older ones. Straight fit and decent enough box. Quote Link to comment Share on other sites More sharing options...
Mo Murphy Posted September 28, 2013 Share Posted September 28, 2013 His is a '95 110 Rich, so it'll have an R380 as standard. Mo Quote Link to comment Share on other sites More sharing options...
reb78 Posted September 28, 2013 Share Posted September 28, 2013 Bugger. I've read too many 'need a new gearbox, will this fit threads?'! Anyway, I agree with your previous post Mo. Fit like for like and save a whole load of hassle. Quote Link to comment Share on other sites More sharing options...
Mo Murphy Posted September 29, 2013 Share Posted September 29, 2013 You are quite right of course though Rich, nothing wrong with an lt77 in the right vehicle Would be nice to find an lt77s for mine. Quote Link to comment Share on other sites More sharing options...
