Have been reading various posts on several boards and gotten some conflicting info. Does anyone know of a list being assembled of the various 5 speeds available that will bolt up to the OM617 in the W123? Have been looking on both German and UK eBay and have only seen 4 speed manual transmissions for sale from the 240D and 300D W123 vehicles that were originally bolted to an OM616 - 7. Have had people tell me that they think a 5 speed out of a 280 SE will fit. Others say some of the early V8 Mercedes had a 5 speed that will fit.

A few recommended a G-wagon 5 speed that had an OM617 because they use a divorced transfer box and it may be easy to fit the main transmission in a W123. There are a number of 5 speeds out of the 190D and various other vehicles (like the W124) that have the starter positioned on the left side of the engine, opposite the OM616 & 7.

I am no expert that's for sure, so sort of thinking out loud: Having had a machine shop make engine adapters and flywheels in the past, am wondering if it would be worthwhile to make an adapter that would mate to one (or more) of these later Mercedes 5 speeds that would also relocate the starter position and use a matching custom flywheel with the correct ring gear (that matches the donor transmission & starter). Then one could mate up a 5 speed from an OM602, OM603, 190D, or whatever is close enough to work with a custom adapter & flywheel. Assuming the remaining challenges of the shift lever, driveshaft, rear mount, and so on could be overcome, we could then have a not so rare 5 speed conversion for our W123s with OM616 - 7. Wonder if this is worth looking into?

Robert Someone suggested the T-5 so did a little more research and: The Mercedes transmissions are generally short and stout with the main shift lever roughly positioned above and near the middle front of the main housing connected via linkages to some levers that come out the side of the main housing. This is very much unlike other manufacturer designs that have the shifter out on the tail shaft much further back. Measured a T-5 World Class and while an adapter would make it mate to the OM617, the shift lever in the tail housing is far enough back that someone riding in the back seat would need to shift it after an access hole was cut in the tunnel. So to fit a T-5 would probably require fabricating complicated linkage and most likely modifying the transmission tunnel to accommodate.
