Stage 3 Performance Transmission Build – 8HP70 / 8HP75 / 8HP76 | 1500 WHP Turnkey Build with Round Trip Shipping

The ATS Stage 3 ZF8HP transmission build is engineered for extreme horsepower applications pushing 1500+ wheel horsepower and 1300+ wheel torque. Designed for drag racing, roll racing, street performance, and high boost builds, this package transforms your factory ZF8HP70, ZF8HP75, or ZF8HP76 into a transmission capable of handling serious power.

This service requires sending your transmission core to Applied Torque Solutions for rebuilding.

This purchase does not include a pre-built transmission core.

Need a built core instead?

This is a build service — you send us your transmission and we build it. 

If you can't have your car down that long, we keep pre-built cores available so you get a ready-to-install unit and send yours back afterward.

Core availability and pricing change with what's on the shelf, so it's quoted per build and added to your order total. 

Call or message us before you order and we'll confirm what's available for your application.

After ordering:

1. Remove your transmission from the vehicle
2. Securely strap it to a pallet
3. We coordinate FedEx Freight pickup and transport to our facility
4. Transmission is built, tested, and returned to you

Typical turnaround time is approximately 2 weeks including shipping, though times may vary depending on workload.
