Blew a cooler hose today
I got a hole in the transmission cooler line today where I insalled a magnefine filter about a month ago. The truck barley got me where I was going. I fixed the hose and filled her up with 5 quarts of fluid. Anyone know if I may have done any damage to the tranny when this happened. I only went about a mile on the lagging transmission.

You will never know without pulling the trans and taking it apart to inspect the internals. Driving one low on fluid is a fast way to damage a trans.
I would just fix the leak, fill it up and drive it, take your chances, drive it till it drops.

You need to open the clutches, inspect the bearings, etc. None of that is possible by dropping the pan, like jk080 said.

So just because you're an automatic transmission engineer, you think you know something about this? Don't you need to be mildly qualified to comment on this forum?
Seriously, though, what are the chances I did some damage? I noticed it goes into reverse a little slower. Forward gears seem fine.

You might have damaged something. It's really impossible to tell without tearing it down.
I once had a Crown Vic on a chassis rolls that I was running a cooler test. The chassis rolls were in a different room. There were three of us in the control room BSing while the test ran. The test was a 30 minutes test, and the temps didn't get hot enough to have to watch closely until at least the 20 minute mark. At the 10 minute mark we started to notice that the engine noise seemed to go up. We looked at the instruments and realized the wheels had slowed from 60 MPH to 10 MPH, and the engine was on the rev limiter! We quickly shut it down. Inspection found that where the tech had tapped into the cooler line to install the thermocouple and flow meter had leaked and dumped enough fluid that the trans ran out.
We fixed the leak, refilled the trans, and finished running the test. After the test was complete we took the trans out and tore it down. There was no damage.

Your story makes me feel better. I lost 5 quarts of fluid. Do you know the minimum amount of fluid it takes to keep the transmission working? I'm not looking for a diagnosis, but I'm just really curious about the mechanics. Sometimes I think I should have stayed in engineering in college.
