<VV> No Corvair - Duramax

[BBRT]

Anyone - Heard of any service bulletins or problems w/ '03 Duramax and Allison re accel or kicking down issues? May have gotten some bad fuel but the truck wouldn't pull up the big hills like it used to, under light load;
 24ft trailer was empty. (Changed fuel filter at PW4). Would run easily at 75 mph but just wouldn't accelerate like it used to.

Bill Hadley-pls email me offline.

Thanks
