Just making sure where these attach - I am seeing a few drips on the right/front side of the transmission pan. without crawling under the car, I think the cooler lines are on the left side, but maybe not?

+1 passenger side of trans... driver side of rad on boxes.
driver side of the trans is either the gear selector port or the pan itself.

Big thank you guys. Saved me a little time this morning. So the leak may actually be one of the cooler lines then - that is the side it is on. Are the lines on these cars prone to leakage?? I know pan gaskets can wear too, just a bit surprising that this started up suddenly.

My experience has been that the lines are not prone to leaking unless they have been disturbed, but that's just my experience so I would be curious to see what others have to say.
I once had the lower fitting smashed on my 89 MGM, I have no idea how it happened but whatever hit that fitting somehow left no evidence anywhere else on the trans that it had been there. It was definitely a wtf moment when I found that fitting disfigured and leaking with no other damage anywhere near it.Vic

Mine aren't leaking but they are starting to look pretty crusty by the oil pan. Up higher, they're fine. I gave them a coat of rust paint to hold them over longer but I can see them become an issue in the next year or so.
Also, just a side note: besides that my car isn't really rusty at all besides some surface rust. (Surprising for a life long Long Island car)Last edited by slack; 03-18-2015, 03:04 PM.

Some of this depends on the attach method. I think your car is late enough that they do not have the quick connect fittings anymore, but those really sucked as far as leaking, especially if they had been disturbed at all. If it looks like 2 hex fittings screwed together, you have conventional flare fittings. if its only one hex thing screwed right into the trans with the steel line going into that, you have quick connects. The trans end should be the same as the radiator end, so have a gander there first.86 Lincoln Town Car (Galactica).

Well, it was the pan bolts loose. One of the front/center pan bolts was also missing. Service manual says they are M8 x 1.25 x 15, which seems right length wise, but typically the head on an M8 bolt is a hell of a lot bigger than 10 mm hex. I could only find 20mm length at Lowes home improvement, so if that is the right thread pitch, will cut it off. Also, forgot to mention it's a flange style bolt.95 DGM Impala SS, 383, LT4 cnc heads, LT4 matched intake, Holley 58 mm t/body, GM 846 cam, GMPP 1.5 rr's, F-body MAF, BH OBD I PCM, LT4 knock module, K&N cold air, Edelbrock headers, Flowmaster exhaust, BBHP #73 6-speed, 4:10 gear, sloted and drilled rotors, Z28 cluster

yeah its a funny bolt with a flange and a reduced size head. You could cheat and just use a flat washer instead if it comes to it. I don't have any extras here or I'd just send you a couple.86 Lincoln Town Car (Galactica).

No worries - I just cut it down to 10mm with a dremel cut off wheel and cleaned the threads up a little. Damn thing has a 13mm head.95 DGM Impala SS, 383, LT4 cnc heads, LT4 matched intake, Holley 58 mm t/body, GM 846 cam, GMPP 1.5 rr's, F-body MAF, BH OBD I PCM, LT4 knock module, K&N cold air, Edelbrock headers, Flowmaster exhaust, BBHP #73 6-speed, 4:10 gear, sloted and drilled rotors, Z28 cluster

RETURN (cool) line
Pretty much the same on the rad. AOD uses the bottom for return while the AODE/4R7x uses the top.

If the plumbing made sense, the bottom on the radiator would be the hot side, and the top would be the return. I would not expect it to make sense though. From memory here, my factory cooler plumbs into the lower fitting on the radiator.86 Lincoln Town Car (Galactica).
