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

Features & Benefits:

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.
