check the fluid level in the box, it's very possible its on the way out.
AR25's are fitted to 2.5TD's and they all go bang around 120k miles - If you do replace the box, make sure its an AR35 as they are much stronger

All I can tell you, seeing as it's an Auto and the engine actually stalled, is
that it's not necessarily a Gearbox fault.
Being an auto, there is a fluid drive between the Engine and the Gearbox,
not a direct mechanical link. So there can be some variance between the
input and output speeds of the gearbox.
The ECU will have a set of parameters built into it, an operating envelope if you
like. If these parameters are exceeded, it will put the gearbox into Limp manual
mode.
When my Crank sensor was playing up, sometimes the engine would try to stall,
revs drop down, road speed normal. If it recovered without actually stalling,
the gearbox fault light would come on and the go into manual operation only.
All would reset on a restart.
Not saying this is what happened to you, but bear it in mind and don't automatically
condemn the Auto box.
There are some chaps on here that are on intimate terms :) with every nut, bolt,
and widget on the diesels, and I'm sure they'll be along soon with a check list
for you to carry out.

What are the AR 35s fitted to, the 3.2s, when it said they go bang, does it refere to the gearbox is stuffed.

Dunno for sure but theres a fair bit on the forum already.

but more likely, this in maintenance guides - http://www.omegaowners.com/forum/YaBB.pl?num=1183142571

If the engine stalls, its not uncommon to get a false 'gearbox fault'...
Worth doing the fluid and filters as a matter of course...

Thanks for your suggestions i have just been out again [ priorority club meeting ] i will check fluids asap ;) this weekend if i can pinpiont the cause i will post back findings :-?

Gearbox fault will also appear if you were to forget to fit the throttle position doo-dar after you've done your cam belt change ..... apparently ::) ::)
;D ;D ;D
