GDP MPVI3 TCM Support Package (2001-2010 6.6L Duramax)

Allison 1000 Trans Tuning

For those wanting just a tune and not the actual device, we are able to offer tunes only. This requires the purchase of a new support pack for the VIN# of the new truck being tuned.

Please note that this package includes the tune file exclusively and does not come with the MPVI3 device.
