I know GM doesn't recommend towing in fourth, but any of who do it on a regular basis? How many miles on vehicle? any problems?

I routinely tow in 4th. No problems. Of course I have a 4.10 rear, but I've seen many others on this forum who use 4th as well.

I tow with my 6.5L/4L80E in OD always, and I got 150,000 miles out of it before the OD planetary exploded...If you've got the power, use it.
Cheers
I have 220,000 miles on my 4L80E. I tow in OD all the time.
I always tow in overdrive with my truck unless it starts hunting between gears.Originally posted by farmerherb:

4L80E = tow in overdrive unless it starts hunting between gears
4L60E = never tow in overdrive

154,000 miles and still counting. Use 4th most all the time unless I need to pull it down to a lower gear in advance of an autoshift. I keep the converter locked above 35mph, with the "BD" "Torq-Loc" which keeps the fluid cooler, also gives me extra gears. ie; 1st, 2nd, 2nd(locked), 3rd, 3rd(locked), 4th, 4th(locked), Works great with 7 ranges.

The 95 trucks had a sticker on them saying to not tow in OD. I haven't seen one on the 96 and newer ones.
When I purchased my 96 -- 3 years ago I had to sign a form from the sales dept. not to tow in OD. Tried towing without OD an got lousey mileage. Went tyo OD with much better results. Except of course when engine starts hunting, then I downshift, 193.000 miles so far.

That's an old wives tail brought forward from the 700r4 trans.
My hub odometer on the trailer has 87,000+ miles on it and all of that was in OD. That why I got rid of the 86 Sub and the 700r4.

How do you get 2nd gear Tork-Loc? Do you have the DIY resistor installed that I've read about in the DP? I only get lock-up in 3rd and 4th with my Sub. I could use 2nd lock-up with my Tork-Loc and US Gear exhaust brake coming down some long mountain grades out West.
BTW, I tow in 4th all the time. I saw a maximum of 210 degrees transmission temp., the other day, coming up out of Bullhead City, AZ,. That's a 14 mile pull, up, what, an 8% grade? With 170K on the clock, I think that speaks well for the L80E.
