Good Morning CF, I'm replacing the transmission line that runs from the bottom nipple of the radiator to just in front of the NSS (at least I think that's what the adjacent triangular part is). I'm stuck, literally. I've watched several vids of folks using these plastic disconnects with smiles and ease (my metal one doesn't go small enough for this line). Copious amounts of degreasing and kroil have gotten me to the point of getting the disco in there and I heard it pop/snap.

However, I can't get the line to let go. I've pulled on the line with and without pushing in on the disco. Can I maybe use the shaft of a long screwdriver behind the line for some pulling leverage? I have about an hour in so far of the described attempts. I've also pulled the disco out to make sure I hadn't broken it (although I did break part of the tab portion yesterday). When I re-inserted the disco I indeed heard it snap in again. If I simply need to keep pulling, that's fair and by all means let me know, but I'm otherwise at a loss for any other logical method.

As always, thanks in advance, I appreciate any help/ideas/criticism.

Use a 7/8" open end wrench (offset is the best) and turn the coupling out of the trans. The tube will come with it.

I had to do this. I was going to change my couplings as well as my tubes anyway.

Edit: Have a drip pan under those couplings when you pull them. You'll get several quarts of ATF out of the ports.

Thanks Ken, I considered that route. Of course, I assumed that the fitting would take the line with it, meaning the fitting wouldn't rotate without also rotating the line (which wouldn't work-no place for line to go).

I'll go give it a try and see what happens. I shall also kick self in butt for relying on assumptions. ha

Progress: None (well, hurting hands)
I definitely need an offset 7/8 for the line I was attempting. Since I'm doing the other line (waiting on tomorrow's parts for that), I thought I'd give the rear-most fitting a go for funsies to see if it would work by taking the fitting off with the line still attached. That one is NOT budging with the 7/8, although it also hasn't had a kroil bath til now.
Unfortunately, I have to clean up now so as to look like a normal mom at a school event. Next go at it not likely til tomorrow eve. So thanks, wish me luck, and I'll check in to report progress hopefully

Those couplings are tight. I had to position the wrench then tap it with a hammer to get it break loose.

Good luck.

Convert to AN fittings..

Why?

Just squeeze the ends squeeze him and pool at the same time and it should come out.

I thnk she said she tried that.

Then you do not have to deal with the POS plastic clips anymore.

can you show a picture of the conversion
