Could someone recommend a good trans cooler for a '04 Tahoe with the 5.3l. It has the towing package but I'm not sure if it has one already stock. Regardless I'd like to install a heavy duty one since we are now using it alot for towing. Is this something that can be installed on your own or do you need a pro to do it? Also if anyone else has any suggestions on inexpensive upgrades for towing they are more then welcome. Was thinking of some sort of trans oil temp gauge as well. Power on it could be way better but it does the job and were in no hurry to get up hills just want to get there without blowing up. I guess any inexpensive power mods would be nice if they will make a difference.

thanks in advance for your help

 

Here's a site with information on transmission coolers and a chart to decide what size you need:
