Customer Reference 6-speed transmission

“I have converted my 230SL pagoda to the 6 speed gearbox because the old 4 speed transmission demanded such high RPM from the engine. I feared this may cause future issues for my SL and I wanted more out of the car. My local specialist installed the new 6-speed gearbox and it fitted perfectly. The installation was definitely worth it, driving the 230SL is really fun now! The engine now runs at an optimal speed range between 2000 and 4500 rpm. I will not reinstall the original gearbox for now and leave it in storage. Regards CLB”
