Hi everyone,

just wondering where the breathers are situated on the gearbox and transfer case of a 92 Sierra, also do you have to tap into them to fit breathers or can you do a similar thing to breathers on the diffs?
Any help would be great!

The gearbox breather is on the top of the box above the arrow pointing to the bolt.

do a search, they have been fitted with breathers before, but do bear in mind that the shifter is really badly sealed and is only 1.5" higher up.

Search is your friend.

Thanks heaps for your help Steve! Now with the breather on top of the gearbox I searched and people have said that the holes are on the side so if you place a hose over the top it will block the holes! Any suggestions? Could you maybe cut the top off?

You are correct, the holes are on the sides. Ideally pull the cap out, tap the box for a 90˚ barb and put a hose on that, but as I said, do consider that it's tough to seal the shifter so it might be a bit pointless.

Ok maybe forget extending the breathers on the gearbox then if it's gonna be a sieve in other places haha. But is the shifter on the transfer the same?

It seals better (and is easier to seal)

I've filled a transfer with mud and water twice. Never a gearbox.

The shifter on the gearbox should have a round rubber boot over it covering the top plate with 3 bolts

The shifter on the transfer should have one also, but with a metal band that wraps around it holding it in place in a groove
