FAQ

Questions.

What is included in the price?

The complete built transmission, assembled in house in Anna, Texas, with new seals, gaskets, pan and filter. Shipping is no longer in the base price — drop your unit off at the shop (call us to schedule) or add round-trip shipping when you order.

What is the core charge and why is there no number for it?

There is a core charge on built units, quoted with your order. It depends on the unit you send in, which is why we cannot print a single figure here. You will know it before you pay, not at checkout.

How long will I be without my car?

Usually about two weeks for the build. If you choose shipping, add transit time both ways. If anything changes, you hear it from us before you have to ask.

What exactly do I ship you?

The transmission core — the complete unit as it comes off the car, without the torque converter..

Do I need a torque converter too?

Recommended, not required. A converter built to match the transmission is how you get the full benefit of the build.

How much power will it hold?

Our ratings start at 1,000 WHP at Stage 1 and climb with each stage — the exact figure depends on your transmission family. Pick your car above and each stage shows the rating for that family alongside the price.

Do you tune it, or do I need someone else?

We do not tune. Plenty of our customers run a tuner and plenty do not — the build does not depend on it either way.
