Rover V8 To Tremec TKX Gearbox Package

We have a 5 speed manual transmission package using the Tremec TKX transmission and designed for the Rover V8 engine producing high HP in conversions of TVR, Morgan V8, MGBV8, Cobra’s and Hot Rods.  The Tremec TKX transmissions are the ideal choice for high HP Rover V8 engines.  The TKX is built to handle 600lb/ft of torque and the updated transmissions benefit from being able to accomodate a number of 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.  We have three choices of TKX part numbers that will fit with our bellhousing, giving a variety of gear ratios.

TKX Ratios are:
1st 1:2.87
2nd 1:1.89
3rd 1:1.28
4th 1:1.00
5th 1:0.81
Rev 1:2.87

There is an option to have a 0.68 ratio on the above transmission.  The 0.81 beng the choice for road race style and the 0.68 for cruising with lower revs.

Our transmission package is available with all parts to install a manual transmission behind a Rover V8 engine or as a package of parts that allow the customer to utilise their existing flywheel.  We have three options for clutch operation – cable operated fork, external slave with fork and internal hydraulic release bearing.
