Removing Transmission oil cooling line - The 1947 - Present Chevrolet & GMC Truck Message Board Network

So what's the magic with removing the trasmission oil line from the transmission of '76 305 elky? hhmm, I don't know the model of the tranny, but it's a standard AT. It looks like you need a special tool, some kind of open socket because you can't get a wrench or anything around the bolt from the side and the top face has the line coming out of it.
I'm puzzled?

You need a Line or flare nut wrench. It is an box end 6 point wrench with one of the sides missing.

hhhmm, I'll have to take another look but I don't think I had space to use a wrench like that. there doesn't seem to be room to move a wrench sideways. hhhmmm

I think this is your only option.

It is a be-otch to get to those tranny fittings.
Trust Chris on the line wrench. You don't want to round them puppies rounding off. Try reaching up from behind the tranny. It's ackward but you seem to have more room to get some leverage. once you have them loose you can use a regular wrench.
Also If you have a torch and a spare line wrench, heat it up and bend it so it is easier to use.
You should see all the single purpose tools I have custom bent.

Maybe a crowfoot flare nut wrench?

Slonaker's got it--you need the crows foot wrench--at least in my experience.

Kenneth · 10-23-2003, 12:58 PM

yeah, the crows feet look like they'll work fine. Unfortunately Sears doesn't carry them in the store, so I just picked up 11/16 flare nut wrench. I'll give it try and then see if I need the crows feet version. Thanks for all the help!
by the way, where could you get the crowsfeet flare nut socket thing?
I don't know of general online tool supply stores.

ive always just used the flare nut wrench without a problem i dont know guess thats just my luck tho

Slonaker · 10-23-2003, 05:21 PM

I bought the crowfoot version at Harbor Freight Tools. Their tools are not good quality, but very inexpensive. The quality is usually good enough for a "use it every few years" tool.
