stock tranny limit?

[04Cumminz]

my dad has a 2006 with 80,??? miles and was wondering how hard he could push the tranny? just for towing bobcats and equipment like that?

I'm not sure what you mean by "how hard can he push it" but it all depends on how he drives it...

Is the engine stock?

I know someone who tows his bulldozer and backhoe with a '96 one ton dually auto. He eventually had to do a tripple disc and valve body but it was stock for a long time.
