Just want to get this in the knowledge base:

What we're calling the "Early" model manual transmission is (at least externally - it's two pieces:an aluminum bellhousing and cast iron gearbox ) the same transmission that is installed manual transmissioned W115 chassis ie: 1975 240D

What we call "late' transmissions are a 'one-piece' aluminum casting.

I have not found any information regarding the internal gear ratios on any of these transmissions.

Earlier diesels (220) may also have the same gear box too.
