Choosing A Torque Converter

Here's a quick tour through a typical TCT converter. Beginning from left to right, there's the converter cover with the stator and sprag inside it, the turbine and turbine hub, and the front cover (lying face down). Above the converter assembly are the various bearing assemblies used in the converter. TCT uses sealed roller bearings, not sandwich-style, for its converter assemblies since they are more durable and can handle twice the load capacity.
The TCT 10-inch street and strip converter for our C4 comes ready to install with new mounting hardware. While most of the trick features are hidden inside the welded case, the anti-ballooning plate is welded around the hub of the converter cover on the exterior. This thick plate prevents the converter from "ballooning" by adding strength to the stamped cover.

We'll be honest: We're far from experts on torque converters. Sure, we know their basic operation principles (fluid in an impeller is spun and transferred to the turbine, multiplying torque in the process), but like most of you we had no idea what torque converter to run in our Dynamic Racing Transmission C4. We left it in the capable hands of the people who make them every day. With some basic knowledge of your engine specs, driving style, and so on, the crew at TCT can put together the right converter for your automatic Mustang. We ended up with TCT's 10-inch "street and strip" converter with a 3,000-rpm stall speed. Whether it's for simple cruising or something snappier, TCT can build just what you need. The photos show the inner workings of our 10-inch converter.
