We have a complete package to put the Tremec TKX behind Small Block and Big Block Chevrolet V8.  Built to handle 600lb/ft of torque the updated transmissions benefit from accommodation for 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 1:0.81
Rev 1:2.56

We also have the option for fifth gear with 0.68.  The 0.81 tends to be favoured for road race style and the 0.68 for lazier 5th gear with low revs.

Our transmission package is complete with all parts to install a manual transmission behind Chevrolet V8 engines.  This package assumes the customer has a pre-1986 style small block (with two piece rear seal) producing up to 450HP for street use.  The billet flywheel supplied in this package is 153 teeth (check that your block or starter motor will accept this).  The larger 168 teeth flywheel, together with the 1986 onwards engines (one piece rear seal) and externally balance units can be accommodated at additional cost.  The package includes a billet slave cylinder for use with most ¾” bore slave cylinders.  The clutch fork will also accept cable operation.
