How mail-order service works

1. Purchase this service.
2. Complete the service request form using your order number.
3. Remove and securely package your PCM.
4. We STRONGLY recommend that you use the white 9″ x 3″ x 12″ pen+gear brand boxes available at Walmart. They are strong, made in USA, and cost about $1. Most GM ECM and PCM fit in these perfectly. Just add a bit of paper on the ends to prevent it from sliding in the box during transit. 
5. Ship it to

6. We complete the service and return the controller with tracking.

Not sure which PCM you have? Compare the case, connectors, label, and service number with the GM VATS controller guide before ordering.
