run out of tranny oil while driving
 

As the title says, my beauty ran out of transmition oil while I was driving on the HW 15 nord, in Laval, Canada this mornig at -14 degrees centigrades.
I drove for 1km without oil, then replace the broken hose and refill with new oil. Now only 1 and 2 works. It slip on 3rd and 4th. Due to the cold, I decided to go back home so I drove in 2nd gear for about 10km.
What do you think is cousing 3rd and 4th to slip?
What do you think should I test?

if you ran it dry you probably damaged the internals because of the lack of lubrication. how much did you have to add?

When I ran my GMC truck low on transmission fluid it burned out the 3/4 clutch pack, and it required a rebuild :( I do realize that it is a different transmission but they all work about the same.
