133,000, I'll take the risk of being banned from a Citroen Forum and post a couple of pictures below.

Was not intending to buy her, but with the price I was offered it would have been rude not too.

Cheers for everyone's advice by the way, much appreciated.

I drew that conclusion after taking many rides in the passenger seats of auto owners whose boxes regularly failed.

Dean - do you mean changing the round oil filter with the O-rings, or otherwise?

Yes Adam, I have decided to change it now, with it having twin skins it is rather hard to clean it completely, especialy if the fluid is mucky and the filter has taken a beating.

Umm, the only rational explanation I can think of is that applying a bit of brake will cause a non-adaptive 'box to 'hunt' between gears but by golly you'd have to have your foot well on the brake pedal to do that and before anything untoward happened in the gearbox department, I'd expect untoward things to happen in the braking department such as red-hot discs and pad wear measured in days...

Also, these days the engine and gearbox ECUs are a bit savvy in that they know it's not right for the brake and throttle to be pressed at the same time and will take some sort of retributive action against the illogical condition it sees.

If anyone suffers from riding the brake in an auto it's dead easy to cure. Just keep your left foot tucked under the edge of the seat and behind your right.

Indeed, even on manual box vehicles if you touch the brakes the ecu instantly cuts boost pressure on turbo models, i know that.

That's how I usually tell people to drive them if they have not driven an auto before. As if its out the way they cannot use it.

Also I point out to keep the hand away from the selector as (psychologically perhaps?) they stood on the brakes with the left foot when slowing down

, automatic (no pun intended) reaction to having to depress the clutch I think. ?

As the topic is sort of non PSA autos:

My Astra auto drops out of drive if you are at a standstill and have the footbrake on for more than a few seconds. Appears to rely on the brakelight switch and the speed sensor, sensor at zero and brakes applied (again only after x seconds) Picks up fine though no roll back even on steep hills.

A quick whizz though the manual shows its normal and to prevent the fluid overheating, it is a bit strange though as my old and decrepit Mondeo I had around 2002 never did that. I do find it slightly disturbing though.

On a positive note the dealer told me it was "sealed for life" (I think not I've changed it twice already to empty it more or less fully) and they thoughtfully fitted a dipstick at the factory too. I wish the later PSA box's had one though.

I'm a bit long in the tooth chaps

I got to threatening to cut their b**** foot off.

I'm not too familiar with the latest boxes having been brought up on Borg Warners, GM Powerglides and ZFs of which I've repaired many in the past. and many Mini auto boxes and the Renault boxes which caused some diyers nightmares, if they fitted copper core plug leads the geabox went berserk picking up stray signals.
