I have a 2006 1500 4x2 extended cab w/ 5.3 engine. I use the truck for towing my Jeep to the mountains for some offroad fun. Last weekend while climbing one of the hills, my truck started shifting erratically and by the time I got to the top of the hill I could have the throttle pegged and it still wouldn't down shift. After reaching the top and going down the road a bit the problem diappeared, any idea what the problem was? Need a better trans cooler? All fluid levels were good. Thanks for the help.

Sounds like you need a cooler regardless of weather or not you had any problems at all.

So the stock coolers aren't any good? Any recommendations on a good one?

You can get a big ebay one for cheap...couple people on here running them. I'm running my stock one and has seemed to hold up this far.... Will be upgrading down the road for sure though.

I just put a B&M SuperCooler on mine, part #:70264, got it from Summit for $60, it is a nice plate cooler. There are a bunch of guys on here that suggested it. It is nice compared to the crap fin style you would get for the same money at your local auto parts house. Good luck.

Are there any other mods that I can do to help with my towing?
