Filler neck removal

92 k2500 suburban 4l80 filler neck has a hole in it. How do I remove it?
There should be screws holding in the plastic retainer.
Remove the grounding strap, loosen the hose clamp, use a fairly long thin device/screw driver and separate the hose from the neck and pull the neck out of the hose. Oh yeah, and the breather hose too needs its clamp loosed and hose separated from the steel tube.

It's the transmission filler neck, sorry
 
you can most likely get to it from the top on the passenger side. it's usually a studded bolt, one that holds the trans to the block, then a nut that holds the tube. 15mm iirc, once the tab is off the stud then it should come straight up and out with a little twisting action.

now getting it fully out is another thing. sometimes depending on how much room you have it will come out from the top. other times youll have to pull it out from the bottom after it's out of the trans.
 
Before you remove it:
Clean the dipstick tube and transmission area where it goes in. Dirt builds up there and you don’t want to get anything inside the hole when removing it or reinstalling it.
After you put the new oring on the tube, coat bothe the oring and the metal where it he oring goes in with atf so that it installs properly and doesn’t damage the new oring. A twisting motion helps it come out and go back in.
