Sun Coast Converters Allison Transmission Build - Bulletproof Trans Buildup
Sun Coast Converters is known throughout the diesel truck world for its top-of-the-line torque converters because it has taken the time to listen, learn, research, and respond to customers’ suggestions with outstanding results.

Examine this statement from the company: “Our mission is to identify all cause of complaints, failures, and inherent malfunctions in OEM transmissions. We will formulate data and technology, and design and manufacture parts to correct the cause of complaints and failures. We will increase torque capacity through data and parts, and exceed demands created by the addition of increased power and load. We will deliver a superior transmission that will put the power and torque of your diesel to the ground, with durability and drivability.”
These are some pretty lofty goals set down by the founders of Sun Coast Converters, established in 1989 by Joe Webb and Ron Wolverton, but the words ring just as true some 20 years later. The company was founded on the premise that quality in manufacturing, durability, and performance was the only consideration in torque converter production.
By responding to a market that demanded a superior product, Sun Coast has enjoyed continuous growth and success. With the introduction of light-duty diesel trucks in the early ’90s, Sun Coast responded to the increasing demands for torque converters and transmissions that would enhance the performance and durability of the light-duty diesel truck. Production began in limited capacity and as reputation and demand grew, so did the company. Starting with two guys and 2,500 square feet, Sun Coast has grown to more than 20 employees and more than 20,000 square feet. The company has grown tenfold, but the goals have remained unchanged.
Countless racers, sled pullers, dyno mavens, and serious torque enthusiasts trust Sun Coast to build their transmissions and torque converters for them, so we thought we’d get a closer look at a transmission being built with the company’s parts.
Dennis Perry at TS Performance in Bowling Green, Kentucky, needed to get an Allison transmission fixed up (for use in a C4500 truck), so he sent it over to Walt’s Allstate Transmission (270/781-3791) just down the road in Bowling Green. There, Big Earl Talley used Sun Coast Converters parts to beef up the Allison.
Take a tour of the internals of an Allison transmission as we visit TS Performance (for the uninstall and reinstall) and Walt’s for the build. Thanks to Sun Coast Converters for the info.
