Transmission Rebuild & Upgrade

High Performance Transmissions
Most stock transmissions are not designed to handle the increased torque of the tuned and upgraded engines. Their limited torque capacity results in extensive wear and damage when these transmissions are paired with high performance engines. In other words, upgraded engines require high performance transmissions to achieve the desired result.

For customers who require exceptional performance grade of their transmission, SHIFTFIX Transmissions offers rebuilds using high performance parts. We work with only trusted manufacturers such as Sonnax, Trans-Go, Raybestos, EXEDY, Borg-Warner, Superior Transmissions Parts, etc.

Our team has completed several transmission upgrade projects, including building transmissions for drag racing cars. Click here to learn more about our team. Book an appointment by phone or using the form below and we'd be happy to discuss your project.
