Is this a 5.3 or 4.8

Traction control trucks had DBW, also some tahoe/subs' had DBW


look up for example SPoolin on PT.net and his Kermit. his i believe is a 01 that had traction control with DBW

Looks like you know your stuff. I just looked up the PCM and its for a 2001-2002. The number on the PCM is 12200411. The guy I got the engine from told me it was out of a Tahoe but he is not sure of the year. Well the PCM at least narrows it down to either 2001 or 2002
