Designed for the serious full-tree bracket racer, TCI® Transbrake Transmissions deliver the quickest and most consistent reaction times in the business. These transmissions are blueprinted and built one unit at a time to ensure that you get quality parts. Designed for horsepower ranges of up to 750 horsepower, they are able to withstand the rigorous use of week-to-week racing and back-to-back passes. Available in both reverse and standard patterns (on select models only); Pro Tree versions are available and have a “neutral” reverse for safety.

  • Full manual valve bodies with full race clutches & bands allow for quicker shift timing and the ability to run higher line pressures than with an automatic shift transmission
  • Higher line pressure makes it more difficult for clutches to slip under high loads
  • Oversized sprags & races (where applicable) increase holding capacity; steel hubs increase durability & strength
  • Improved lubrication system increases amount of fluid sent to planetaries and internals
  • Designed to handle up to 750 HP
