I expect that for @vulcan bomber and all of us if we could somehow get a picture of how many units are out there? Total, working and non working - it seems quite a few of us have more than one?

I'll modify an oak peg to make a bung. I had severe memory loss after Sepsis during lockdown, resulting a a new heart valve - so I cant remember which has the faulty sensor But - I previously had issues that were caused by the flimsy wiring loom that went up the gear stick, so I'm wondering whether to look at those too? Triggered by your comment about there being nothing in them to fail - I'm wondering whether we are heading in the wrong direction Has anyone got a wiring diagram? Maybe a simple jig could be made to test the sensors - Somebody could chuck-up a (Blunt) Sawbalde in a lathe or mill or drill and introduce a sensor (carefully) to see if pulses are generated? I'll get my coat!

Sorry missed this - Yes be happy to lend you it - But I'll need a bung to stop the ATF draining out - maybe the sensor from the 'shelf' one?

https://www.maximum-overdrive.com/ seem to sell it - $185 very little info on their site though

I have 2 - one in my 110 V8 - Not in use due to a lack of the speed sensor, and another "Sulking on a shelf"

Yes - Its a possibility that the wrong fuel went in - But would a Puma 2.2 run on 60% Petrol? for 150 miles?

Defender 110 2015 Utility XS I filled my tank up, with 2/3rds V Power on top of a 1/3 of an existing tank of Tesco Diesel. We went 70 miles to Bristol Dual carriageways and Motorways - When we got close the engine started to 'miss', loose power intermittently, jerk (not violently) - We were moving flats for my daughter and made multiple trips across the city - then headed home. The problems only seemed to occur at low speeds, Not low revs. Once we were heading home Dual carriageways and Motorways, no issues. When I went to fire her up the next day she is very reluctant, clattering unhappily. We kangarooed down our short track, then down the single track steep hill we live on in 3rd using momentum to her her running. At the bottom of the hill she cut out and I got the engine management light. I pulled into a passing space. the engine had stared running in a very rough fashion, slow and ragged. by now it was POURING white smoke out the exhaust - so much so you couldn't see across the lane - people were stopping to see if I was OK? after a while it revved-up and I carried-on. now it was in some sort of limp mode not revving above 2000 RPM, and pretty gutless (but after a mile no more smoke) after a few miles I stopped on a steep down slope, turned her off - then re started - All good, still had the Bristol hesitation, but the power was back, and I could rev it as much as I wanted. I nursed it into town, and after an hour of 'Cardio Rehab' It was very reluctant to start - but got me home despite the 'Bristol hesitation'. I enlist the help of a friend who is very good with all things Land-Rover, and he suggests a problem with the fuel, We replace the fuel filter (preloaded with redex pump and injector cleaner) and put a gallon of diesel in the now half full tank. It reluctantly starts, runs badly, makes smoke (much less than before) LR Mechanic Friend turns off the engine management light. says he thinks I must have filled it with Petrol. the residue in the tray from changing the fuel filter has what might be construed as a petrol small, I'm not convinced. The main question is this - If i had put 50 litres of petrol on top of 30 litres of Diesel - would it have run? - unless you can advise differently it does seem like a fuel contamination issue - but I'm not sure what. It is pretty galling that having pushed out the boat and put V-Power in the tank - this is the result. Thanks

Dont! - I worked for a company who's Foreman/Manager set out the dwarf wall for a newbuild Oak Barn using his dads linen tape (that had been left out in the rain) Guess what??

We did have a long chat about it in 2015 - (probably triggered by me - I think of these GKN gatherings as the school reunions I never went to)

Thanks for the info Gents. I can remember looking through the RS Catalogue at the time (early 2004/5 maybe) and having the same problem with the thread and diameter, it would be a benefit for all the GKN owners if you had a tried and tested solution? Thanks Bill

I suppose its time to raise the hoary old GKN Overdrive issues. This was precipitated by the return of my old 110 CSW 300 Tdi M Reg having spent the last 11 years being trashed on my sisters little farm. I had this from 1999 to 2010 put 100K on it with no real issues did a lot of towing and the GKN was an absolute god send - you can select exactly the right gear for every situation - and being able to change on the fly was a real bonus. Needless to say - the GKN no longer works, the speed sensor being the likly suspect. So now I have 2 110s with GKNs that dont work siting outside. I haven't approached Devon 4X4 since they sold out of sensors years ago, and wondering whether anybody on here had come up with a solution? Thanks B

Hi I'm gearing up to buying another new tilt and I'm looking for information on a Durable Winter Cover for my 1956 86" Series One - We are quite exposed, and Canvas tilts quickly get trashed, as do the Tarps that go over the tilt. I have learned that quality tarps are the way to go, but was wondering whether anyone knows of a decent Durable cover (which will be a good fit) Also does anybody have views about breathable / non breathable covers? pros and cons. Cheers B

As will I shortly...................................................

Yes, we have a VDub T4 camper too (sadly neglected) - it will always start first time - as will the V8 until recenty - This whole thing is a ball ache! Tomorrow -I'll post a picture of my home made 12V battery pack (made with life expired PC UPS batteries - rejuvenated by the CTEK charger) The VW T4, The series one, my daughters VW Fox, and the V8 have all had new batteries recently, all Numax I think!
