Tow Hubs

As long as there is oil in the transmission, I've not had an issue. I have an old sling type tow truck and have made well over 1000 tows with it with no problems. Some as long as 60 miles. I just cruise on the freeway at 55 for the most part. If it's an early trans (with a rear pump) you have to make sure the tranny is full or you will burn it out. Maybe I've just been lucky?
