Brand new AC Delco TCM pre programmed to your VIN. Just install and go.

Requires core shipped in advance.

Please note: I did not diagnose your truck. If the new unit does the same thing as the old unit then it's a misdiagnosis, but the transaction is final as there are no returns on electronics once installed.

We keep these in stock and program to your VIN so you can just drop in and go.

Used replacement model A40 TCM module for the 6 speed Allison transmissions in LBZ and LMM trucks from 2006-2008. Programmed to your VIN and stock calibration.  30 day replacement warranty.

The 2009-2010 LMM and 2011-2014 LML trucks used the A50/T14 module. Please be sure to check what your vehicle has in it. It is etched into the case in very fine detail.

These things used to be commonly available, but suddenly in short supply so the price has gone nuts. Standard pickups and vans should use the NEW units. Kodiaks cannot use the new ones so we save the used ones for those vehicles. -JK

This item is for those who already own an EFI Live Flashscan unit, but would like to purchase tuning.

EFI Live licensing and loading of the tuning is handled by the end user.

These plugs go into the vehicle harness sub connectors to protect the terminals while the sensors are unplugged. These plugs serve no electrical or circuit completion/fooling purpose, only to protect the terminals.

These gaskets are generally destroyed when removing the DPF as the heat seems to fuse them to both flanges. Includes both the 4 hole (front) and 3 hole (rear) gaskets.

These gaskets ship independently of the DPF test pipes. They can be packaged easily with Kennedy Custom ECM's etc. but not the pipes.

Order this for making changes to your custom tune file. Shipping will be additional.

Basic tune changes include passlock reset for engine swaps, speedo recalibration, factory updates, and fixing of basic Diagnostic Trouble Code issues or restoring a lost tune.

"This is not a complete tune. It does not fix P0087 issues. It is only a basic fix and requires the ECM to be sent in to us or a suitable core must be provided. We will not provide a core for this item." -JK

These injectors are either reman with new Bosch nozzles.No corners cut. Return of matching cores in good condition within 30 days is required or a non refundable $10 per injector will be applied.

Trucks: 1982 to ABOUT 1988 used the long body injectors, but the changeover point was somewhat vague as some 1988 trucks had the new cab/body style, while others had the old body style. Using the cab/body style is a pretty fair way of telling. The long and short body injectors WILL interchange. It is the vans (all years) and turbocharged trucks that need the short injector for clearance. - JK
