Designed to be a replacement of the earlier model TR-3550, the TKO has been significantly upgraded, making it more flexible and versatile. The TKO is ideal for street / Strip applications.

Features:

• Higher center distance (83 mm) from main shaft to counter shaft allows for larger gear sizes and higher torque carrying capacity

• Close gear ratio (2.87 & 3.27) models available for high-performance racing applications

• Robust transmission design with internal 3-rail shift system with cast iron shift forks

• Tapered roller bearings on input, output and counter shafts improve performance (reduced noise factor).

• All gears and shafts made from special grade steel (ASTM 4615) that permits increased torque carrying capacity

• Single-piece countershaft that better handles increased torque carrying capacity

• Equipped with a high-performance short-throw billet aluminum shifter that isolates road noise, while providing clean crisp shifts

• Neutral safety switch and back-up light sensor

• Flexible and versatile:

  • Eight shifter locations available

  • Dual electronic and mechanical speedometer pick-ups

  • Three unique cross member-mounting configurations

  • Three different input shafts available

  • Three available overdrive ratios

    • .64 or .68 ratios reduce engine rpm to a level that makes it fun to drive besides enhancing the fuel efficiency

    • .82 ratio is ideal for long straight-aways for high performance racing
