X2 ;)

If it's only jumping out off fourth I would be looking at the selector first.When gearbox's start doing that it's because of excessive endfloat but because it's only one gear I would look at the selector.For the doubters I ran ATF for 400,000k's before changing to oil and my gearbox has never been touched.

Can't really recommend it, it's totally out of spec compared to something like MTF94, at least to the casual observer.
About to try another one soon that would be considered even more radical.
I should have been taking samples and getting them analysed like the engine oils.

Hopefully I'll be using a stabilised HOBS based (High Oleic Base Stock) vegie/synthetic engine oil before autumn too (if everything goes to plan).

The Defender is going green !

ditto.
A weak/broken detent spring will do this too.

I won't comment on Pat's use of ATF :p

I think it is about $6K or so to auto a 300Tdi Defender.

if its only 4th as mentioned check the selectors and detents as well as the selector housing for a build up of crap and corruption.

if its not that and its only 4th and the box is not making any other noises more than likely its either gunk behind the baulk ring thats not letting 4th engage complete or a problem with the synchro unit itself.

price up the parts for the syncro bits for 3/4 then compare that to the cost of a swap out reco or second hand box.

there is just enough scope for it to be a loose selectors on the rods but I wouldnt bet the farm.
