It's completely silent under load, it's only when off the gas it moans and groans like a bearing has failed? It went for a complete recondition and was Willies original gearbox on 68,000 which I replaced when I got him in 2003. I expected the selector to be much smoother than it is as well?
The place that did the recon was Cumbrian transmissions which were recommended.
I also replaced the seals on the transfer box and the drive shafts as well as all new inner and outer boots inc the propshaft boots prior to the Istanbul trip. The old box was noisier under load but completely silent on the overrun.
I got a second opinion on it as I'm a bit under the weather at the mo, from a mechanic I know locally and he's said it's knackered. I also noticed earlier that there was some drips of oil on the ground which is a leak from the box so it needs sorting.
It's in all gears and the box has only covered a couple of miles from being completely topped up.
