• IMPORTANT NOTE BELOW:

This should be a left hand 5.7 Chevy with a PCM V-Drive on the back of a 40s transmission.

It would be good to make sure your information matches the above.

Also would be great to get photos of the engine tag, the transmission tag and a photo of the v-drive so we can be sure. Text the 3 photos to us directly at 803-766-8586 or you can e-mail to us at [email protected]

This kit is non-returnable unless defective or damaged in shipping.

Note that this kit replaces the 40s and connects to the PCM v-drive. The kit does NOT include the v-drive.
