I've had this car for a few years now, and have never gotten the transmission drain bolt out. I've had a couple of guys attempt MIG welding it and impact wrenching it out, to no avail.
Today I brought it to a really good muffler guy.
He MIG welded this bitch on.
Loosened it with a ratchet and a rubber mallet.

I go home & drain the tranny. About 1qt comes out :|.

Filled with 2.4 liters, shifts goooooood now! =)

I'm gonna fill it with synthetic fluid in a few weeks.

Yea. That's a common problem for our cars.

Its a square shaped plug which freaking sucks. You always tend to strip an edge.

So are you keeping that 1/2 drive as your plug from now on?

Usually, some PB blaster, spray the shit out of it. Let it sit for a few hours.
Get a 16mm or 17mm forgot which one. Open end wrench, slide it in.

Get a breaker bar and break it loose.

Was that your first tranny fluid change since you bought the car? :nono:

That sounds correct. Gearbox and diff usually don't need much fluid.

wow i've never heard of this being a problem on our cars, looking at that drain plug, i would suggest getting a new one, the threads look a little funky.

and possibly the fact there is a fucking impact socket welded to it?

We ended up having to do the exact same crap.

Just be sure to clean the threads real nice when you replace it and put a little ant-seize around the threads and hole.

Next time will be smooth like butter.

Hmm, I dont know, I was able to stick a 1/2" drive breaker bar directly onto that plug and get it out, first try, when I first did my swap like 3 years ago. After that, when I put it back on I wrapped it with teflon tape, so it hasn't been a problem since.

Some tranny's just like the rough stuff.

Well then handcuffs, whips, and leather should have been enough to get the plug out.

Not welding.

I remember when I tried to get mine out. At the point where I had my hands and head wedged up against my wheel and my feet pushing on the breaker bar and it didnt budge, I said fuck it, still shifts and called it a day.

Mine was a bitch and I considered welding a 1/2" drive socket on the plug. I got mine loose after heating the plug with a propane torch and cranking on it. :rawk:

I had a new 1/2 drain plug for my tranny & already installed that bish.
I'm keeping the old one for memories.

Do you fuckers think i'd actually REUSE this shit?
Ghetto 240 owner?

I know I should have kept it filled :|. That's my bad.
But prior to this I tried EVERYTHING.
Breaker bar, Hammering in a socket & blasting away at it with a impact wrench, torch, PB blaster, everything. I should have taken a picture of this shit, it was pretty much a concave dome. No edges to grip on to. I tried those locking wrenches on the open threads, nothing on that either.

It wasn't a triple square either. It's a 1/2 drive socket. straight up.

Anyway, good tip on the anti-seize, I'm gonna smear some of that on in a week when I do the flush again.

You need leverage. I had my car up on the highest jackstand setting and i took the stock exhaust from my accord and put it over the handle of my 1/2''. Came right off :)

leverage isnt gonna help if theres nothing for the 1/2 drive to catch on :ugh:

It's actually not a 1/2" square drive, which is why a lot of folks round the hole out by using a 1/2" extension/breaker bar.

It's a 13.1mm square, and there's a socket for it. I bought one from thetoolwarehouse.net

Breaker bar with jack lever added to it, while the car was on a harbor freight jack.

Not jackSTANDS, a jack.

lol.

Mine was a bitch to get off the first time I changed my transmission oil. After that I put anti-seize compound on the plug before I torqued it back on.

haha this sounds like my 3 day long oil change


the douch i bought my s14 from tightened the oil filter way too tight and it seized...tried every wrench in the book and nothing worked...stuck a huge screwdriver through it and tried to turn it but ended up ripping the whole thing in half...then i lit it on fire and got two huge channel locks...i grabbed on from the top and and my buddy grabbed on with a channel lock from the bottom and both twisted and it finally came off

we lit that shit on fire and kicked it across my neighbors lawn...i still keep that shit to remind me to never tighten a filter like that douche

Each of those plugs may have different heads, but both have the same thread. The only other difference is that the drain plug is magnetic while the filler plug is not.

I like to use the filler plug in the drain hole for extra piece of mind due to the magnet being able to pick up any particle that floats that high.

Also as a tip, the drain plug and filler plug on the diff is the same thread so in a pinch you can interchange gearbox and diff plugs.

If worse comes to worse you can always get a cheap pump and to pump out the fluid either through the filler hole or from inside the cabin by removing the shifter.
