Product Description

These modules are GM units and you will receive a 1 year warranty from us at PCM of NC. We will also program your VIN and latest GM operating system onto it (included in cost).  All connections/connectors are confirmed good before the part leaves our location. These modules do not include any performance tuning. If you would like to purchase tuning or a core with tuning please click HERE.

We do not require your core to be sent in as a core charge refund on this listing.  These are purchased outright.

Please note: Any time you install another PCM into your vehicle that is not original to it, you will need to do a security relearn and a CASE relearn (whether it is from us, the dealership, or any other vendor). The security relearn can be done by yourself, it is a simple process. The CASE relearn (crank angle sensor error relearn) needs a Tech 2 scan tool or a higher end snap on scan tool to complete. Needing a CASE relearn will not keep the vehicle from driving, but should be done within two weeks of install if prompted by a check engine light for it.

    Thank you soooo much for for a great service & support PCM OF N.C. I am so pleased for the job they have done for wife’s h3 06′ ” PCM -TCM” for whatever it cost well worth the price. More h.p. pulling my 19’ft boat is a breeze also not mentioned “TCM” Transmission is shifting way better than factory settings. Enough said! If you need to upgrade your PCM & TCM send it out & you will experience & feel the difference! Thanks again! Very highly recommend!!! 😉
