Manual six speed transmission that bolts right up to your OM601-OM606 as well as M111 and M10X engines. They are in used, good working condition.
 
These had to be imported from Europe, since they were never sold in the US and are very hard to come by. They are from CDI's so the gearing is for diesel engines. They are very stout. One of our customers uses one in his W210 with 170cc of fuel and 3 bar of boost!
 
There are cheaper manual transmissions out there, but you'll need an adapter plate kit, which are usually over $1,000. These bolt right up to your engine without any modifications or adapters needed.
 
Clutch kit, pedals and shifter are available separately here on our website. 
The RWD transmissions ship via UPS ground. The AWD ones are too heavy for UPS and need to no shipped via LTL freight. We'll contact you after you purchase to provide LTL quotes for you. 
 
*Please note that these are used and over 20 years old. They are not perfect and may or may not have the clutch slave cylinder, hydraulic line, rubber output flange, etc...
