Heavy-Duty RV Transmissions

This is the perfect transmission for your two-wheel drive towing and heavy-load trucking needs. These units have valve body modifications that increase cooler flow and improve shift characteristics without the harsh feel of a racing style transmission. When used with a TCI® Heavy-Duty Towing torque converter, you can be sure the transmission package is tailored to provide long, dependable service and maximum fuel economy. The optional low gear package offered with each of our RV units is a great addition for trucks pulling heavy loads.

Maximizer™ Transmissions

The Maximizer™ 4x4 transmissions bring performance to your four-wheel drive. A four-wheel drive application is especially tough on an automatic transmission and the addition of bigger tires makes the job even harder, We designed the Maximizer™ series to be as tough as your truck, because they are built with the best components available and programmed to provide crisp shifts time and time again.

Full Manual Competition 4x4

Whether you drive a sand dragger, hill climber or tractor puller, TCI® has the transmission for you. The competition line of 4x4 transmissions is built following the same specifications we use in building thousands of drag race units. Applications are available with Trans-Brake valve bodies, also. Most popular listings are shown in the chart, but if you have special requirements, please contact us and we can custom tailor a competition unit to your specifications.
