I noticed today that my transmission cooler lines are seaping and plan to replace them soon. They are not dripping so will it hurt the transmission to drive it?
 
I would play it safe and leave it parked. If the lines are rusted a seep can turn into a blown out line any time same thing with a weeping o ring fitting or hose under pressure.
You probably wouldn't know it till it is too late.
 
The lines on my Cruze were weeping for a while. I don't know about your vehicle but I'm unable to check the level in mine. There was never a drop on the ground. Just some oily dirty lines. When I had it repaired I was shocked at how low the fluid level was.
 
Some vehicles' lines just weep. I've heard of people (notoriously, GMT800s) replacing weeping ones with new ones and a week later the new ones weep. Unless you're under warranty or losing copious amounts of fluid, I wouldn't worry too much about it.
 
Self flushing!

I had to patch the metal lines on my Cherokee after an incident where the upper control arm sheared them off. They leak a little bit right now but nothing serious. I consider it self flushing.
 
I've had this issue after fitting a new radiator and lines to the Alero. Very difficult to get them to stop leaking at the fittings. No dipstick on my car (thanks GM) and I was surprised at how much fluid it took to bring the level to normal after the first repair.

You might have a walk-home, but probably won't hurt the trans. On a sudden loss of fluid you lose converter pressure and basically it just won't go anymore. Assuming it doesn't spray on the exhaust and catch on fire, which is pretty rare.
