If you've only just bought it then go back to the dealer but first of all get in and just see that the lever feels "positive" in its movement. Put the main gear lever in first or reverse at a standstill then with the High/Low lever in neutral pull it back into High with the clutch in, keep your hand on the lever and gently let the clutch out and feel to see if the lever "meshes" into gear fully. You might find that as you let the clutch out that it fully meshes into gear. It might be something as simple as the sound proofing(yes it does exist!) is hampering the lever throw or the linkage needs adjusting slightly.
I'm not saying driver error but sometimes Land Rovers with their "up to date" technology need a bit of help  |

Hi JWL,
Thanks for this, and yes, it works as you've outlined. It feels like it fully meshes into gear but what I wonder is if it'll come out again as I travel. When I put it in gear yesterday I believed that it fully linked (can't be 100% sure of course) but then it came out. Unfortunately the dealer is a ship and 5000km away in Middle England. This is something i'm going to have to take care of locally. |

when changing from hi to lo , lo to hi best to move lever drive forward few feet then give the lever another tug to make sure its fully engaged

Hi Munch,
Thanks. I did this before a short drive out earlier and it stuck fast as was supposed to. Hopefully between your advice and JWL's it should be ok. Only time will tell.. the locals around my neighborhood are going to be wondering why that guy seems to be driving in circles though.. |

As has been said it is not uncommon for the transfer lever not to be fully meshed but still be in enough to provide drive until it decides to pop out usually at the most inconvenient time - ie under power. Using the lever every now and again will help to free up th mechanism and keep it free. Steve.

It can be a case that the gear selection rod has not been adjusted right from the factory. That was just discovered on mine after 5 years! Russell

Hello fellow defender owners.
I too have recently taken delivery of a Defender and although very interested in cars, this is my first dip into the off-road market or anything out of he norm. After travelling almost 500 miles, I too have suffered the same fate of loss if drive but only when stationary. I have experimented with this lever before but during a very short burst of towing, the lever popped-out and think that I also incorrectly engaged when putting it back in drive. Now I've experimented and selected a gear allowing the lever to operate freely, I can now 'feel' the lever engage fully. As I'm suspicious with your problem Bastion, at hand-over the dealer did not explain how the lever worked and said 'as long as its down there somewhere, it'll be fine for the road' this is fine for the short-term and until reading the manual, but what the manual can't show you is the feel you get when it's fully engaged. Anyone know the significance of driving with the lever only partially engaged, giving drive? It this likely to contribute or cause damage? I don't think I've done all 500 miles like this but certainly some. One time I could hear an incredibly faint shinning noise on acceleration and convinced this was when it was not fully engaged!? Any thoughts would be appreciated. |

'Whining' noise, not shinning! Not so smart phone.

A whining noise (or even a shining noise!) is unlikely to be the result of only having partial engagement of the high range transfer gear dog clutch.
Prolonged use of the vehicle with the high range gear not fully selected is likely to cause wear on the selector dog clutch, but in all honesty it is unlikly that you will have caused any problems, damage, or wear with what you think you've done. I really wouldn't worry about it! The best method for engaging either low or high range is to have the engine running, the main gearbox in gear (probably first or reverse, but in reality any gear will do). With the clutch pedal presssed firmly to the floor, move the transfer gear selector lever smoothly and decisively into neutral then into the destination gear. It may or may not feel as though it has moved fully into gear, but in either case very gently ease up on the clutch until either the lever moves the last fraction, or the vehicle tries to move. It should be unmistakable. When this happens, clutch pedal down again, then go about your business. it is comparatively rare (especially with a nice tight new transmission) for the engagement to be full without this (or an equivalent) technique. It is all part of the joy of Defender ownership - the fact you have to work at driving it and understand what it is doing! It is possible under fault conditions for the transfer box to jump out of gear. Like all traditional gearboxes, the selector is held in gear by spring-loaded detent balls pressing into notches in the selector shaft, and if these are sticking then there is nothing actually prevent the selector shaft and fork assembly from moving and jumping out of gear. Also, more commonly, iif the external parts of the gearshift mechanism are covered in crud it can prevent full travel of the mechanism, and this can prevent the detents from engaging. |

TBH the high / low range lever only being partially engaged yet still delivering drive [until it pops out with a bang usually at the most inconvenient time] can even happen to us salty old beggars who have driven Land Rovers for decades
The system is an old design so time needs to be spent to ensure proper engagement. If you drive with the lever partially engaged you may, or may not, notice a little more slack in the transmission - but much depends on how tuned in to your vehicle you are. Steve.

I've had this happen to me
But it only happens immediately after using low range. I've found that it's me not engaging it properly, now I select high and lift the clutch slightly whilst pulling it back into high. If it does jump out stop the vehicle before trying to select high again. I did it with the clutch in once I'm gear but rolling and the bang scared the life out of me. I guess it's a straight cut box, no idea if double de clutch would help. 2014 - current ..... 2003 defender td5 90 (my car) 2009 - current .... 2005 zx10r |

I had the problem recently of the xfer box jumping out of high (always went properly into low). Sometimes it would go in properly and stay in. Sometimes no matter how I tried I could only get it partially in, and it popped out at an awkward moment. Turned out to be that one of the retaining clips Frc8548 in the linkage had come off and the pin had worked half way out resulting in some lost travel. I could see it from underneath the car and also by shining a torch down the hole in the gear tunnel (foam removed). New clip on and all good again.

I suspect you mean "clutch out", ie pedal pressed, which if you're rolling is likely to make bad noises unless you match the gear speeds (as you do when double de-clutching). The problem of course is that everything between the clutch and the intermediate gears in the transfer box will stop moving after you've pressed the clutch, whilst the output shaft of the transfer box will be moving, driven by the wheels. Result, nasty noises. Clutch in, and provided you match speeds correctly, it should be silent.. The LT230 transfer boxes are helical cut not straight (early vehicles were helical on high and straight on low) and are constant mesh on both gearsets. Selection is by dog clutch and there is no synchro. |

Thanks everyone for your comments, stories and knowledge. I always knew Defenders had huge followings but maybe not aware of just how much. As a new owner and novice who is willing to learn, it's very nice to know there is loads of advice and help out there at the click of a button.
It makes every sense that it will take time to tune into the car and understanding of how it works will come with time and experiences I guess! Anyone know of any links to any good diagrams of the transfer box so I can see what is happening when I'm operating it? My new toy: Nov 2015 90XS hardtop in Santorini Black |
