Is there really any difference in the actual transmissions in the 1/2 ton trucks with the tow package? Still just the 60? Is there anything I can do to make mine last longer if I pull a trailer a decent amount?

almost positive its still the 60E...

Bigger tranny cooler.

I have the tow package and it is a 60E with the oil cooler. I tow a 4000lb trailer some and so far no problems yet. I don't pull regular or over mountains though.

Do you pull in drive or in OD with the Tow/Haul switch on? I just want to make my tranny live as long as possible.

when i pull my 26 foot travel camper i use the tow haul button till i get up to speed. if i am on a straight and level road i will switch to od. but for any incline i drop it to 3 and let it ride there so it isn't shifting back and forth.

I have no idea how heavy the camper is. i do know that i pulled it once with the ******* underneath completely full of water. (didn't know it was full)

I'm estimating my toyhauler weighs about 4000 lbs empty. I tow with tow haul engaged and leave it in 3rd gear. I tried OD once and it kept shifting in and out of OD. I've been told towing in OD creates too much heat in the trans.

I've got a tow package with my Avalanche, and not only do I just have a regular 4L60E, but do not even have a tranny cooler. Ripped !!!

I always just tow in 3rd because if im in any hills or high winds the trans. will not stay in overdrive.

I always tow in tow/haul, but it doesn't seem to gear hunt at all. It will kick down going up long hills, then hit OD once it levels out, or starts down. Just didn't know if it would cause any problems with heat. It seems to do fine, just want to protect it as much as possible.
