ATS Stage 3 5X Build with round trip shipping

STAGE 3 8hp45/50/51 BUILD - 1300+whp/1100+wtq 

This purchase requires you to send your transmission to us for the build. It does not include a pre-built core. However, if you prefer to purchase a built core from us, we do offer that option for an additional fee.

Once you've completed your order online, please have your transmission removed, securely strapped to a pallet, and ready for pickup. We will coordinate with you and arrange for FedEx Freight to pick it up and deliver it to our facility. After the build is complete, your transmission will be shipped back to you.

Turnaround time is typically around 2 weeks, including shipping, though this may vary depending on our current workload.

If you have any questions about the process, feel free to contact us — we're happy to help!
