AOD question(sealing cooler lines)
The truck is ready to drive, BUT I have substantial dripping coming from the transmission cooler lines where they connect to the transmission. I thought these were compression fittings (like brake hard lines) but they aren't. They basically screw into the side of the transmission. From what I can tell, it looks like they were sealed with Teflon tape. Does this sound right? Is there supposed to be O-rings too? Or, just the Teflon tape? I put on both, but the upper one is still leaking (maybe more tape?). The tranny supposedly came out of an 87 T-bird. I'm about to hit it with Hylomar HPV (my favorite sealant). Anybody have any thoughts or suggestions?

You might check with a local transmission shop. I'm sure they wouldn't seal with teflon tape. That's not typical. On older trans, like C4 and C6, they have a brass fitting that screws into the trans and the lines connect to that. I'm sure there's an easy answer. And I'd almost put money on it that it's not tape.

52 Merc, you're correct. The solution isn't tape. The solution turns out to be Dorman 800-609 (at O'Riely's) and possibly Napa part # 730-4956. Apparently the line is a "quick-disconnect" style that has an internal o-ring that is prone to deterioration. Thanks for reading! I guess I need to Google sooner rather than later the next time. Maybe somebody else will benefit form the knowledge.

Yep, still hammering the bugs. It's up on the lift, so all I've been able to do is watch the "wheels go round-n-round" and leave a red puddle. That throttle valve cable is starting to worry me too.

convert to 1/4 pipe thread i had to do that on my aod the treads are 18tpi 1/4 pipe is 18tpi but tapered make sure that you don't tap the hole too deep then you can run 1/4 [ipe to inverted flare for lines and no leaks

I may have to, but I bought the one Dorman connector and it fixed the top leak. I had to order the second one. I'll install it tomorrow. Hopefully, that will be the end of the leaks.

If you don't look closely, mine look just like threaded/flared lines instead of quick-disconnects.

The other line was also a quick disconnect (as it I assumed it was since the first one was). The new connector seems to be working well.

I was tempted to tear it down and rebuild it before the install as it was a junk-yard tranny. But, the last tranny I rebuilt lasted about 15 miles, so I thought maybe I'd better go with the saying "if it's not broken, don't fix it."
