I too, have a transmission (racing only) for sale. It's based in QLD...
Transaxle is Elite Racing Transmission's TXL300 6 Speed SEQUENTIAL with internal oil pump, solenoid reverse lock-out, and Gear knob (with lock out control button). Includes Digital gear indicator. Input shaft is for the LS series engine, and has been designed with the Albins Bell housing and 20mm adapter plate from the factory. The 'box is geared to 293kph at 7800rpm on our usual wide / tall GT40 rubber (ratio / gear sped chart available). Output flange seals have been updated since delivery (by the factory).
Hydraulic release bearing included (ex-factory). Full workshop manuals, part drawings, CAD files, all included. Gearbox can be used for mounting suspension directly to it. The mounting points are exactly the same as the Hewland NLT, with extras too.
Gears are straight cut, with dog engagement. Output shaft PCD is same as Porsche / Holden.
There are 2x adapter plates supplied with this gearbox - 1x large plate with chassis mounting points (as in pictures), and 1x small plate (profile cut around bell housing)
