Any 1998-2001 Vortec 454/7.4l L21 calibration in Kodiak 4500, P30 van, Workhorse etc etc. This uses the dual 80 pin connectored PCM's 16232148 and 16238212 and OS 9354781T, 9369651T and 9384681T

This is a VIN for a 1999 GM P12 chassis on which a motorhome was built. It uses a non computer controlled Allison trans. 1GBMP37B2W3311219 I just listed this VIN for access, I dont need this particular vehciles calibration per se.

Thanks in advance

peace
