Hi everyone,
well this is my first proper post since joining your forum and hope someone will be able to point me in the right direction regarding a problem that i have with my 110.
First off, it is a 2009 XS Utility model with the Puma engine. After owning it for about 6 months i was pulling out from a junction when something snapped and could not get drive out of it (although the gears seemed to be engageing)
Off to my local garage it went. They told me (which i have no reason to disbelieve) that the clutch plate shattered and in the process took out some parts in the gearbox. They sent the gearbox to a local specialist (Bexhill Gearboxes) who had a look at it and said one of the shafts had snapped and they replaced that with an upgraded shaft (commenting that the OMP ones were not unlike carrots)
So after the return of the "upgraded gearbox", new clutch i got the wagon back from the garage and shortly after noticed a reduction in power.
I can hardly get into 6th gear when motorway driving and going up average hills can be a bit embarrassing being overtaken by artic's and woe betide Fonteras! Selecting gears is not an issue, its just once in top gear the rev's just die off and have to drop down to lower gears.

Now for a couple of notes. Before the clutch went i did some minor mods although nothing regarding the engine. I successfully replaced the background of the instrument cluster with a white one from "Tune My Defender" and wound the needles in the correct manor that they recommended, and had no trouble with any of the instruments.
When i got the wagon back i noticed that the speedo was now not working. After mentioning this to my mechanic he made some enquiries and suggested that if the speedo was not working then a rev limiter would come into effect by the engine management system and would explain top gear problem.
Not completely convinced, and loathed to send my cluster off to a specialist i had a word with a local Defender dealer. They said the first thing they would check would be the gearbox transducer which i decided to renew myself, being an easy job sitting onto the gearbox under the centre cubby box.
Still no joy!

Having the speedo not working is not really an issue with me, but if by fixing this it will sort my power (lack of) problems then obviously would get it done. Incidentally, out of gear and in the lower gears the rev counter works fine and goes to red line.

Hope someone can shed some light on this most annoying problem

These Defenders do have a speed limiter and a CAN bus between the IPK and the PCM on which the vehicle speed is broardcast.
I would get the speedo fixed first and take it from there.
I have seen a few of these with stripped splines on the shaft between the gearbox and transferbox but I haven't seen any broken shafts in the main box. The last one we had in was an electric board 110 that had got stuck and broke the transfer rear output shaft, clutch and main box were fine.
