transmission swap... W116-W123?

OK I have a (W123) 1978 300CD non turbo automatic. It needs a replacement transmission. I know where I can get a (W116)1976 450 SEL transmission but I am not sure it will fit the car.

Does anybody know for sure. Or if somebody can tell me the transmissions and bodys that I can put in this car.

115 might work

I am pretty sure you can use a tranny from any 300D even a w115 model - the earlier ones weren't shift controlled the same as the w123's, but still should bolt up and shift.

a w116 gasser tranny will have a different shift and power profile than your diesel - so adjusting shift points might be a little more difficult, but again I think it's been done.

Hopefully someone will chime in that has used a 116 tranny in a 123.
