Question type: Maintenance & Repair
I have an '07 2500 HD w/6.0L gas & 6 speed auto trans. In my owners manual, it lists two possible types of tranny's, a 6L80E, & a 6L90E. I was wondering how to tell the difference & WHAT is the difference in the tranny's??

Thanks Tom! So, 1500's come with a 6L80 then???
Yes a 1500 will come with the 6L80e. The HD trucks get the HD transmission (6L90e)
Buying a 2005 Chevy 2500 HD. Two wheel drive. What trans comes with this truck

I have 2007 GMC Sierra 1500 HD; it shifts fine until the transmission warms up 150 degrees and then it shifts hard going into second gear.
