Leigh. Can't speak about a 105 1hz but a couple of years ago the R151 gearbox in my 2002 troopy stuck a couple of times in 5th. Advice was that this was a known weakness and a sign 5th was on the way out. I got advice from a few sources including lcool forum. In the end I had a H150 and transfer case fitted. Search lcool and you'll find my thread in the 70 series forum.

It required a different clutch plate because of different splines on the input shafts. While there you might as well fit an HD pressure plate and, of course, a new thrust bearing. Different plug on the speedo sender. Different spigot bearing. Shifter floor plate and boots from the donor vehicle. Alteration of the floor mat. It also cost me a lot of aggravation by choosing the wrong mechanic to do the job.

If I the same choice again tomorrow I'd probably buy a reco R151 and be nice to 5th, especially by no towing in it. I'd do the job myself or rather I'd give it to the mechanic who now looks after the troopy because he is a REAL mechanic and not a parts fitter. That said, there is a lot to like about having an H150 and transfer case. Food for thought mate.

There are many ways to solve this issue, with different components etc. Suggest "search" the internet as it has been done to death.
