Frequently Asked Questions
What does “VIN Programmed” actually mean for me?
It means we take your vehicle’s 17-digit Vehicle Identification Number (VIN) and load the exact software and calibrations for your specific 2006-2007 Buick Rainier onto the module. This makes the unit ready for immediate installation and operation, completely avoiding the need for a dealership’s specialized tools.
Where is this module located on my Buick Rainier?

Will this fix a P0700 trouble code?
A P0700 code is a general fault code indicating the TCM has detected a problem.
