I have a 2012 Yukon XL with the 6.2l. The guy I bought it from already modified the motor so the DOD would not engage. (Modified the motor and the computer) It has been running fine for years. Well, now I am having several issues with the motor and have decided that it would be more cost efficient to replace the motor with a rebuilt one. However, all the engine shops want a VIN to go with the motor that you order. Does someone know what vehicle/VIN I could use to get a 6.2l that would work with all my sensors but I would not have to modify when I install it? Thank you in advance.
