Thanks my friend, I needed that

[@raygale4198]

Another easy fix for difficult to select Lo range is check the clevis pin on the shift lever, if the plastic washers and clip aren't installed properly the clevis pin can wander across and foul the gearbox casting as you try and select Lo. Did this very job on my Defender yesterday.

[@williamdevereux541]

Brilliant thanks so much excellent advice

[@BritannicaRestorations]

Glad it was helpful!

[@roy2689]

An old post I know but heres my penny's worth... I've changed the 'O' rings on these from time to time and sometimes found that the grub screw has been tightened so tight ( from the factory) that the the shaft has deformed slightly and if you try to force the shaft out you can damage the bore where the seal rests, so remove the grub screw slide the selector along the shaft out of the way and file the burrs down (it's a bit cramped in there but just perservere with it) and the shaft will come out easily and avoid damage to the aluminium bore...

Charging for sound effects, brilliant! How very Yorkshire. Love to see your down to earth way of doing things, that was the most even but minimal squeeze out I have ever seen, tool of choice, a finger. And why not.

[@BritannicaRestorations]

I think I put too much on! Lol! Problem with these new types of sealer is they dry so quick in the tube make a nice seal but when you come to use the tube again it is solid

[@harveysmith100]

@@BritannicaRestorations You and I both understand the importance of tolerances, we also both know that most things coming out of China have poor quality. Put the two together, the tubes that the sealer come in probable don't seal properly once opened. Try a bit of PTFE tape around the thread before replacing the cap. This is just a thought.

[@adrianbletan310]

From where I can buy that O-Ring?

[@terrybreeze6070]

Hi, I have a 50th anniversary D90 automatic basically a NAS, wont shift into low range tried all the usual rocking back and forth etc but no joy will check the linkage, but if that doesn't work would I have to drop the transfer box out to fix it as per your video cheers Terry

[@urmomgoestocollege14]

Removed the selector and it was fine. Not gummed at all like this one. Interlock solenoid removed. Put selector back on and still won't shift between hi and lo. Help.

[@gmkgroup2459]

I have done as above, lever free. When re-attach still stuck.

[@blessedperson3676]

good day. excellent video. i would like to know what can cause my reverse to slip out. not staying on reverse. and a grinding noise.

[@BritannicaRestorations]

If it is a reverse problem, then it will be in the main gearbox

[@breals_8489]

Hi, to replace the prop shaft bolts it seems like you have to remove the flanges so the bolts can be removed. Could you refit the bolts the other way round to make them easier to change later if needed ?

[@BritannicaRestorations]

No sorry you cannot

[@MattTester]

Turns out it was this pesky little grub screw that was causing my issue, it wasn't even finger tight and I think if I drove the truck again it would've vibrated out and gone through the transfer box. Cheers again. While I've got this off do you reckon it's a good place to fill the box from if I'm changing the oil? Seems easier than the fill plug.

[@BritannicaRestorations]

Might as well do - just make sure the surfaces are clean for applying the sealer

[@MattTester]

@@BritannicaRestorations Will do, thanks.

[@CHAGrady]

Mike, I’ve just put my LT230 back in after replacing seals and gaskets etc. What I noticed is that with a 10mm spanner I could move the difflock mechanism quite easily. However, when I fit the “arm” back on to the bar from the LT77 gearbox. It won’t budge out of difflock. And here’s the kicker, I’ve had my 110 2.5 na for five years and seemingly been driving with difflock engaged all the time!! Would it do damage? I’ve put it back to Normal now with the 10mm spanner.

[@BritannicaRestorations]

I don't think you would be in diff lock for 5 years as you would be buying tyres every month or fitting an centre diff weekly! The diff-lock is funny as you can turn it with a spanner to what seems like 3 positions, but only in and out works - fully to the right ( the little lever on the top of the diff lock) is locked - straight ahead is out You may have to tinker with the adjustment on the eye rod screwed into the gearbox casting

[@CHAGrady]

Thanks for the reply, I’m not sure what’s going on then. The difflock light hasn’t worked in five years but now it does when I use the 10mm spanner to move the mechanism. High and low are fine. Weird

[@whiskeyromeobravo3645]

Is it possible to access that transfer case mechanism cover via transmission tunnel from above - Disco 1 automatic Nicely done videos…thanks.

[@BritannicaRestorations]

Can be done but tight

yes

Hi I like your videos very helpful got a question maybe you can help me while driving the Land Rover it sounded like a loose wire then I gave a gas car will not move I'm wondering if you can help me what would be the problem or what should I look for? Thank you

[@BritannicaRestorations]

Would help if I knew what vehicle!

[@FaithinThoth]

Can that selecter actuator cover be removed without removing the transfer case ?

[@BritannicaRestorations]

Yes you can remover the High/low selector without removing the transfer case - bit fiddly but it can be done

[@lachlanstrong6000]

I have a Land Rover discovery 1 and it goes into hi and low range but as soon as a you back off the throttle and unload the transfer case it pops out into neutral any idea what would be causing this

[@BritannicaRestorations]

It could be the detent for the high low is stuck - or missing www.lrworkshop.com/diagrams/land-rover-defender-transfer-box/transfer-box-lt230/high-low-gear_53751#15

[@neilfrancis3013]

Hi Mike boss my 110 is jumping out of hi range when I'm driving and it looks like the stick goes into low range with plenty of room but when going back it doesn't seem to go so far back any idea thanks in advance because your the man that can lol

[@BritannicaRestorations]

Sounds like the lever is a spline or two out on the high low linkage

[@neilfrancis3013]

Thanks Mike I didn't see your reply lol I had gone around to my garage and stripped it off did exactly what you just said but I haven't had no time to put it back and try it. thank you mate for replying .. I do have some nice classic mirrors I won't to send to you still in the original boxes If I can been told because of covid regulations I can't do anything yet but as soon as I can I will .

[@thomasmccready6390]

has any body done this repair by removing front driveshaft and just reaching in? I have worked on the lock/unlock this way

[@axelwindels5711]

Mine keeps jumping out of diff lock. Really annoying when doing steep hills 😅 Any solution for that? (It’s a 2.4 tdci - same transfer box I assume)

[@BritannicaRestorations]

Could be the detent spring is too weak near the diff lock light switch - or not adjusted right

[@kennethkirwin3934]

Hello my question isn't related to this but is a gear box problem i have i think an r380 box im trying to change the oil however the filler plug which is a torx 55 is so chewed i cant get it out i know i will have to weld a nut on but i dont have access to one right now can it be filled any other way

[@BritannicaRestorations]

You will have to remove the top gearbox cover and fill the correct amount. Refill 2.3 litres

[@paulhancock3844]

I've got a problem where if I select low range to get a heavy trailer into my drive. When I've unloaded and reverse back out, if I take the way from the house downhill, it drops into neutral and I loose drive. If I go the other way on the flat, it's fine. I'm suspecting its not quite fully engaging into high range and when on overrun on the downhill section the gears force themselves out of mesh? Or am I looking at something more serious?

[@BritannicaRestorations]

It could be the spline on the high low lever is one spline out - easy fix

[@paulhancock3844]

@@BritannicaRestorations Cheers, I've had the centre console out enough times now so I think I'm sure what's involved. On another subject but with the main box, what would you say to the plastic bushing on the sector yoke falling apart after a thousand miles? I was lucky in that the bits fell into a location where I could retrieve them. I wondering if the one I fitted wasn't genuine? I've fitted new land rover parts but I'm concerned incase it happens again. I was lucky this time in that I was only outside the house when it happened. I could only select 5th, i put it into low as well and it got me back to the house to do the repair. Bloody land rovers!

[@BritannicaRestorations]

It's a bit of a gamble with parts nowadays!

[@macphestozoo3885]

Great video… question. I just had my transfer case resealed by a Land Rover mechanic. When I installed the transfer case back into car and button everything up now it won’t shift into neutral or low. I can only lock it in high. There is no binding from a visual inspection. Is it possible when it was sealed that it was installed incorrectly?

[@BritannicaRestorations]

There is a detent ball and spring on the top right looking from the front - just make sure that the grub screw is flush, not screwed in fully

[@macphestozoo3885]

Thanks for the fast response!! Is that the grub screw on the lever? Or somewhere on the linkage?

[@BritannicaRestorations]

On the transfer box itself You can see a pic of it here www.pinterest.com/pin/797911258969189886/ On the main body, right in the centre of the pic

@@BritannicaRestorations Ugh unfortunately the grub screw is flush. The cdl worked fine before the reseal. Any other ideas? Thanks for your time🙏

Does this have anything to do with the differential lock?

Same housing

[@RunDub]

Mike, can this be done in the vehicle, or must the transfer box come down?

Pretty easy on a Defender but tricky on a Discovery/Range Rover

[@RunDub]

@@BritannicaRestorations Nuts! I just bought a '99 Disco 1 where it's completely seized. I have a spare LT230 already, so worst case I can swap it in, but I'd hoped to not have to remove it to free the linkage.

[@ChibabaDave]

Ive lost drive on my landy. Feels like the diff lock is working but going from hi to lo feels loose and as if it isnt driving anything. Could this grub screw coming loose be a cause? Im hoping its not the mainshaft

[@BritannicaRestorations]

Sounds like the mainshaft - take the PTO cover off and have a look

[@ChibabaDave]

@@BritannicaRestorations thanks for replying mate. Think im just trying to avoid the inevitable here. Ive got a PTO attached is there any other way to check without taking it off?

[@BritannicaRestorations]

Is the PTO working?

[@ChibabaDave]

@@BritannicaRestorations ive never tried it. It had an oil leak that i sealed up with sikaflex pending a proper strip down. It does feel like one of the links on it might be seized when I was checkin things the other night

Maybe not so easy with the LT230 in situ. But of course it would be difficult to film if You did not have the transfer box on the table :-)))

Mike, I have a 2003 Discovery 2 SE7 (North American Model). It does not have a center diff-lock on the gearbox lever. I have read some Discos nevertheless came with proper internals, is this true? Is there a way to identify this without R/R and disassembly of the gearbox? I there a way to modify the original linkage for this purpose, or is one kit required to purchase, for example from lucky8.com (www.lucky8llc.com/products/ashcroft-discovery-ii-cdl-kit) I love your videos, and passion for teaching us how to properly repair these Land Rovers! Tausend dank für alles!

[@BritannicaRestorations]

The 1999 and maybe 2000 had the transfer box with the diff lock fitted and also the last of the D2's had the diff lock fitted It is very strange but when I converted my V8's to 300Tdi and 5 speed, I linked up the diff lock and lever Never used it on 3 vehicles as the traction control worked perfectly (VERY ODD!) The Ashcroft kit is actually a Britpart kit DA1178 Note from the BP website - Early Discovery 2's were not supplied with a centre diff lock function for the LT230 transfer case although the vehicles still have the centre diff lock installed in the transfer case. To get the diff lock function to work it just needs connecting. The linkage is easy to fit, cable operated and very neat. You attach the existing high/low stud to this new lever assembly. This kit will only work on transfer cases with serial numbers starting with either 41D or 42D. Thanks for the support! Mike
