Anyone towing with 5.3/ 4L60e?

[Seminoles]

Thanks for the info just was not sure this is my first new Chevy in a long time the Buick we had only had D321 and no button so used 3 towing one of Uhaul's big trailers from Texas. (kids can't make up there mind where they want to live) The Dodge Ram I had the button kept the converter from locking up which is the week point and D was a gear sort of. I did try the tow haul with nothing and it ran 2300 and off 2000 like you said does it keep the converter clutchs (the weak link) from locking up too? If I have this right I can tow 7000 to 9000lbs in D with tow haul on flat highway's and 3 in high hill and mountain areas which I plan on staying out of until I can aford a real truck like the big boys. I did tow it a couple of weeks ago it stayed at 2400 even up the bigist hill I will go up seams to be a good ol truck never broke a sweat still need to get the WD set up right still have a sway around 65 found out the guy has 600lbs spring bars and need 800-1000lbs bars that should help a lot. Once thanks for the info....
