Hello, I need help on how to replace the Breather plug. Mine got broken and it needs replacing. Can it be removed from outside or transaxle needs to be dismantled? Does it need a special tool to remove it? Here is the picture. Thank you. View attachment 290402
Looks like you should be able to pull it out and snap the new one in without taking the trans. apart.

Try using a hook pick in the center. Can't tell if there's supposed to be a c clip holding the assembly to the transmission.

I figured it broke off.

Try this. With the hook pick in the through hole, try to tip it to one side and fit a small flat head to reach the push clip.

Don't know if it would work, but worth a shot.

All else fails, take a flat blade screwdriver and heat up the end ( stove or propane stove works) then slide it down one side to cut it. Then take needle nose pliers and grab the edge near the cut and roll the part in on itself while pulling it up and out.

Thanks! I'll try that too as my second option and once I get my replacement order.

Keep us posted. Curious to know if these ideas work or not.

Instead of going down the side as @sdspeed suggested, maybe try using the same heated screwdriver and make a slot down and go as far as you can. That may break it enough to use the needle nose pliers. But hopefully, it won't fall into the transmission.

That too, by cutting a slot top to bottom it should melt away enough material that you can push the slotted edge into the center with the pliers and basically roll it out. Depending on how secure it is where it sits you could heat a 90 degree pick (i.e dental pick) and perice it into one side and hold that in place and make two cuts opposite each other and pull it out as two parts. The tabs that hold it in look like their pretty stout and may need the added clearance. Hopefully it's pliable vs. brittle. At least by using heat there's less chance of debri falling into the transmission. You'll know alot more about what your dealing with once you have the new part in your hand!

Already installed the new breather plug. It took us more than 30 mins to remove and clean everything. Due to the age of the plastic, it is too brittle to pry it as a whole. ? What we did was to melt the plastic bit by bit and pull it out every pieces and clean it thoroughly. Looks an easy job but it is not due to limited space since we did not pull down the tranny.
