I ran into this problem yesterday when trying to change my ATF for the first time in my SE-R. The ATF filler bolt is 5 sided bolt, and I cant find anything that fits it. I called the dealer and they said it should be a hex head bolt. I've tried Napa and Sears and Autozone. Im sure I could find something custom or rare on a website, but I dont know where to begin.

Don't know what size you are looking for but it's a 5 point socket, somtimes called penta

Also I should also note the only reason I've seen one has to do with my grandpa working for the telephone company.

Since it seems like such a odd thing for automotive use and the dealer says it's a hex bolt, are you sure you are looking at the right part?

 

Yea, its definitely the ATF filler bolt. I did a brief search last night for 5 sided bolt, and the only stuff that came up was for electrical and gas security bolts. I guess whoever owned this before me threw it on there. I'll take a look at those links posted.

Thanks guys.

 

It appears to be a 19mm socket (from what I've read on the web). Do you own metric sockets?

 

How about using an adjustable wrench if you don't have a socket set?

 

A 12 point socket might fit, but its more like 27mm. I dont have any 12 points to try, so I'll prob end up buying a custom socket from one of the links above. PLUS as you can see in the pic, theres a plate that sits really close to the bolt. That just adds to my frustration.

 

he would most likely round off the bolt. that would work best on your usual 6 sided bolts.

 

Can't see the pics at work.

 

when you can see the pics you'll see

 

You might want to look into replacing the bolt with a standard one once you get it off, too.

 

wtf? never seen that or had anyone ask me about that before, ever.

 

Reading the thread title, I thought this thread was about trying to contact msl82

 

^ zing!

 

I'd be VERY sure that's the filler before messing with it. Often a factory will put an odd bolt head in something so that it can't be taken out by accident.
