Default Transmission cooler line question

I've got some corroded transmission lines running under my radiator. I want to replace them myself, problem is i don't know whether i have an auxiliary cooler or not on my car. The lines are upper and lower lines (i'm going to replace both) but there is an option to buy lines for an auxiliary cooler and an option to buy a line that fits without the cooler.

How can i tell if i've got one? Its a 1990 Buick Electra- Park Avenue. A picture would be great. I can't tell from the auto parts online store, which line would fit either. :(
Haynes Manual won't say :(

Any other suggestions before i try the job?

If all you can see is 1 line going into the radiator and 1 line going out, you do not have an auxiliary cooler.

The transmission cooler lines got fixed.. Old ones were terribly corroded, a wonder any fluid was getting cooled down. We were able to remove them with crescent wrench and socket wrench.. and by taking off just the radiator fan. No auxiliary cooler, so the parts fit really nice. tightened up the connections and no more trans fluid on the ground.

Took it to the shop the other day though..and needed new CV joints.. So that hurt the pocket book. But saved alittle money with the line replacement.

next time I was alittle strapped for time and the mechanic (of course he did) said it wasn't something i wanted to attempt on my own. I'm going to work myself up to brake replacement next.

When you get to brakes check if youu need a specail bit to get the calipers off I know on the 97 bonnevilles you need a 3/8 allen bit. Also you will need a C-Clamp or pistion depressor to reset the calipers. It'* a fullying job. Not to difficult.
