Frequently asked questions

Which years of the C8 do you carry?

We carry GMC C8 transmissions from 2003 through 2009. Available stock changes daily — select your year above to check current availability.

How do I know which transmission option my C8 has?

Check the sticker on the driver's door jamb or decode your VIN using the form above. If you're unsure, just submit a quote request — we'll confirm your transmission option from your VIN before we price it.

Are these transmissions tested before they ship?

What warranty is included?

Every transmission includes a 1-12 month parts warranty depending on grade, starting from delivery, covering internal mechanical failure under normal use.

Do you ship nationwide?

Yes, we ship to the lower 48 states. Freight shipping is included in every quote.

We run a small fleet of trucks. Consistent quotes and the test data actually matches on install.
