Mercedes modification with the 722.6 adapter set
Adapting your classic Mercedes M110 or OM 617 engine with a modern 5-speed automatic gearbox (755.6.. series) is now possible. The first question, of course, is why? Below are five good reasons – you have an automatic transmission with 3 or 4 gears and you get a automatic transmission with 5 gears. -The 722.6.. transmission lockup in the torque converter provides a priss direct connection to the wheels at a fixed speed – possibility for a manual paddle shifter. Even with a standard engine you will have an improvement in engine performance and will reduce your fuel consumption. Fifth gear is an overdrive and the lockup can also be activated in gears 3, 4 and 5 This classic Mercedes upgrade makes your car more drivable and more suitable for everyday use
