Is there any trans tuners out there worth a damn for 02 Duramax? Something that helps towing manners.

My buddy hates how his won’t down shift even in tow haul mode. He ends up manually shifting it when pulling. I’m trying to find him something

Are you talking about tuning it yourself or having a "tuner" program it for you?
