What goes here?

This is over by the intake filter and the battery.

 

Looks like the nipple on top of the transmission right where the cables attach. A rubber plug usually covers the top of it. I use that hole to fill my transmission with oil.

 

isn't this where u also check the level of the oil in the tranny?

 

if you have a manual trans, then there is no dipstick to check the fluid level, and that is just a filler hole. If you have an auto then you need to find the dipstick that goes in that hole. If your worried about it, just find something to cap it off with.

 

Hmm, I capped mine off and it started blowing fluid out around the shift fork-- I took the cap off after a 20 mi. drive and it popped off, it was totally pressurized in there. I just left it off- figured it was a breather.

 

thats not a fillelr hole its a vent/breather tube for the tranny. It is suspposed to have a rubber cap that allows it to breathe without worrying abouto anything falling into the tranny.
the filler hole is just behind the axle on the diffrerential.

 

The only correct answer

 

edit: just saw the post about where the filler is for the tranny
