Transmission cooler lines leaking?
During my manifold swap last night, I noticed that the base of the front mount (by the starter) is wet, as are the transmission cooler lines. Both the bottom of that mount and the two lines have the lightest coat of something that looks dark green and feels oily. (My coolant is green, but I filled up five months ago and haven't lost a drop since.)
I asked Bill if the front mount was leaking fluid, but he suggested transmission cooler lines. So, what parts do I need to replace those lines? Would this be a good time to price out an auxiliary cooler?

Check the rubber lines, they may be cracked and leaking there. I would take a degreaser and wipe everything down real good, get it clean. Then give it a little time and see if it comes back. If not, you saved yourself some time and have a cleaner engine. If it does come back, then you have a better chance of locating the leak.

Like I think I mentioned. Where the compression fitting meets the rubber hose is where they typically leak.
I'd check dealer or Rockauto for the lines.

These transmission are perfectly fine with the cool you have. No need for a cooler unless you are going a high stall convertor and dragging on a regular bases.

So what do I need from Rockauto? Just the Dorman lines under Oil Cooling Hose, or do I need connectors, fittings, and whatnot?

I dunno, I didn't research your car. What do the pictures show, full lines or partials?
Another alternative is to slap on an aftermarket cooler and cut/bubble the lines near the trans. Then run trans hose to the cooler and back.

I'm finally getting out of bed today, so I'll degrease the existing dark-green crud and watch for new red crud.

It'* not the build date of the trans, it'* the build date of the car. Look at the door for the month/year. I found out my car was born 11/22/96 when I did my trans lines.
Either lines will work BTW..might not clip in the exact same spot under the radiator, but that'* it.
