2001 Chevrolet Silverado 2500HD 2dr Regular Cab LS 4WD LB (6.0L 8cyl 5M)
This is my work truck. Replaced a 98 K3500. I use this truck to pull heavy fifth wheel trailers. The duratec diesel engine is great for this. Loads of power w/ great gas mileage (20 mpg highway). I have the optional allison automatic transmission. The tranny is great for downshifting when pulling trailers. The tranny did shell out last year w/ 50,000 miles on the odometer. This cost $4500 to fix. After doing some research found this is a common problem on the 01 model. My fuel sending unit also went bad. Cost $800. Research also shows these trucks are prone to premature injector failure. I havent seen this yet though. Wish reliablity was better I guess.
Chevy needs to address their Allison tranny issues and back them up.
