🔥 PRO STREET CALIBRATION

This is a forward-pattern automatic C4, not a full-manual or reverse-pattern race transmission.

Put it in Drive and let it shift automatically. The Pro is calibrated for a firmer, quicker 1–2 and 2–3 shift than our Street build without turning your classic Ford into a harsh race-only car.

The performance intermediate band and valve-body calibration are selected and set up together for the C4 being built.

⚠️ TORQUE CONVERTER NOT INCLUDED

Please select a torque converter from the available options if one is needed.

If you purchase a converter with your transmission, we will supply the correct converter to match the C4 being built.

If you are reusing your existing converter, you MUST verify whether it is 24-spline or 26-spline before ordering.

⚠️ PLEASE CONFIRM 157T OR 164T

You MUST verify whether your current application uses a:

• 157-Tooth Application
• 164-Tooth Application

Flexplate is NOT included.

⚠️ 1964½ & EARLY FORD APPLICATIONS

If you have a 1964½ or early Ford application, please confirm your 5-bolt or 6-bolt bellhousing pattern before ordering.

Do not go by vehicle year alone. Many of these vehicles have had the engine, transmission or bellhousing changed over the years.
