PRO-SHIFT™ 10-Speeds

The PRO-SHIFTTM 10-Speed transmissions are designed for over-the-road and city applications. TTC offers many configurations of the PRO-SHIFT 10-Speed, including a complete line of direct drive and overdrive configurations.

For weight sensitive or bulk hauling applications, consider our OPTI-LITETM and OPTI-LITE IITM options. They reduce transmission weight and allow you to haul more payload.

For on-/off-highway applications, the vocational 10-Speed transmissions were built with startability, gradeability, easy shifting, durability and sensible gear splits in mind.

Vocational 10-Speed transmissions are available in models to match most application conditions, axle ratio and engine specifications.

Proven in millions of miles of operation, all of TTC's PRO-SHIFT 10-Speed transmissions feature:

  • OPTI-LUBETM standard feature
    • No oil cooler required
  • Exceptionally smooth shifting
  • Driver-friendly shift pattern
  • Isolated shift lever and tower assembly reducing noise and vibration
  • Highest torque-to-weight ratio in the industry
  • Wide choice of PTO applications
  • Quiet operation improves driver comfort
  • Deep first and reverse gears for excellent maneuverability
  • Low cost of ownership and purchase throughout entire service life

How can we assist you with your specific requirements?
