TCI Maximizer 4x4 Transmissions

3.4 out of 5 stars 30 Customer Reviews

Bring out the performance of your 4x4 with these Maximizer transmissions from the folks at TCI. Four-wheel drive vehicles are tough on automatics, especially with the addition of a lift kit and larger tires. Maximizer transmissions are built with that in mind. Each one is assembled with the strongest components available and designed to provide crisp shifts, time and time again. They give you all of that, and they'll deliver long and dependable service, too.
