Look into the engine compartment it's the big silver thing attached to the engine. aaaaaahahahahaha
The gearbox breather hose.
The Peugeot 406 is made by french car makers. This is large and spacious and sedan type look. The lines are sleek and finished. The interior can be tailored to fit you.
they are black in colour and have a multiplug connection on the side of them
on the right hand side of the engine as you look at it, remove the airbox to gain access, what does it look like
Under the air breather... Remove air breather and look down right there and not too bad to get to. Hope it helps.
look on the ebay
get gearbox number off gear box and look it up online.other than that try counting the different positions of gears
due to the complexeity of an auto gearbox i would suggest a replacment of the gearbox as the cost of repairs will out way the cost of a good secondhand unit. so to save the head ache go to an auction look for a written off car the same as yours and salvage for the parts needed. or look for a specialist breaker for a new gearbox.
look on the valve cover right behind the oil cap. if it is like mine it may just have a breather that looks like a cap in it's place. you just remover the breather thingy or pcv whatever the case may be and insert the new valve. if it just has the breather cap you may have to rerout an extra vacuum line to it from the main vac source or something. Anyways, hope this helps
Look at the V5 document.
