Disco 1 Auto breather

basquen · Apr 8, 2018

I'm getting pressure building up in the auto transmission - ATF dipstick comes out a couple of cm by itself.
I guess there is a breather blocked but I can't find where it comes out of the gearbox. Can anyone advise so i can clean it out?

if my memory is correct it is high'ish on the nearside of the box

my auto box dipstick does the same, but I have extended breathers so would be surprised if mine were blocked

Thanks - I'll check tonight. Do you know if this is a threaded connection or a push fit?
It must be well tucked away so not sure I'll be able to get a spanner on it if I can't even see it.

there is a 1/8th bsp thread in the box hi up possibly on top near side and something is screwed in to it that has a piece of pipe attached, can't remember how the pipe is attached.

My gearbox dipstick also does this and has done for the 7 years that I have owned it. gearbox operates perfectly though so I just push it back when I have the bonnet up and ignore it. I would have thought if it was a problem, something would have broke by now?
