SUBPAR
I have driven several GM products in my life, and this truck is one of the worst i have seen. i not\iced the transmission tended to slip between the lower gear shifts! Classic Chevrolet informed me that Chevrolet put the wrong transmission in the truck. this version of transmission was designed for HIGH altitudes (such as Colorado)
I am still wondering way they told me that and didn't change it out.
At least Car Care USA repaired my Differential that went out at 34,000 miles!!! Thank you Car Care USA
