In the US, the W201 and W124 were the last models that offered a 5-speed manual transmission. All the M102, M103 and M104 engines take the same bolt pattern bell housings . . . so, a transmission, whether auto or manual from a 190E can be installed on a 300E, etc.

Flywheels, torque converters, miscellaneous fittings will have to be engine specific.
