TKO600 Ford V8

The Tremec TKO 600 transmission has the highest power handling capabilities in the Tremec 3550 range.  The TKO 600 handles 100 lb/ft more torque than the TKO 500 gearbox which in turn has a higher torque rating than any of its model predecessors (the standard 3550, the TKO and the road race TKO11) all of which gained popularity as a high strength replacement for the T5’s.  Built to handle 600lb/ft of torque the updated transmissions benefit from accommodation for 8 different shifter locations, provision for mechanical and electronic speedometer pick up, reverse lamp and neutral safety switches and a high performance, billet aluminium short throw shifter.  This shifter isolates road noise whilst providing a clean crisp feel together with a unique biasing system, which is adjustable for personal preference.

In order to achieve the increased torque capacity, the manufacturers now use a higher grade alloy steel (4615) on all gears and shafts, have increased the diameter on the output shaft to a 31 spline, and eliminated the woodruff keys on the countershaft by going to a one-piece design from the previous three piece.  The shift forks were also completely redesigned and are now all made from cast iron and use a three-pad contact system -virtually eliminating any deflection. 

Ratios are:
1st 1:2.87
2nd 1:1.89
3rd 1:1.28
4th 1:1.00
5th 1:0.82
Rev 1:2.56
