w115 240d -> 5 speed transmission from a w123

Hey there!

i have a w115 240d with a 3.69, and feel that it revs a bit to much doing 60mph/100kmh, having found a 5 speed transmission from a w123 230e i am wondering how much trouble it would be replacing the the current 4 speed with that, or if that doesnt work how much trouble would it be fitting a 2.47 or something axle from a w116 se450, anyone done it?

(worth to mention is that the 240d engine is from a w123, so a tad more power, but i got a stock 240d 3.0 available, and might put that in later)

thanks in advance!

The five speed for the 230E has the bump for the starter engine on the "wrong" side. Other five speeds from the W123 are possible, but you'll need some more parts than just the transmission.

thanks, and to bad :/
btw what more parts are we talking about? might find another 5speed, but this one was in superb condition :/

might give up that 5 speed thing, and just go for a low geared differential or something :/ anyone now about what need to be done when taking a diff from a 450 w116, geared 2.47?

Driveshaft (shorter), intermediate plate between engine and transmission, shift rods, shift knob, longer speedometer cable, different clutch cylinder, perhaps some other small stuff.

Is your 240D an automatic? If so, a flywheel change is also needed (and you need to transfer the balance of the old flywheel to the new one).

A 2.47 final drive is probably too much for the 240D, unless you're happy with a very slow accelerating car. And if you are constantly pressing the pedal to the metal to get ahead in the city, you'll not safe fuel.

Then il probably pass on that.
It will have to run as it is then, or if i find one of those rare 3.07 final drives i might go with that.
Either way, annual costs goes from (on my w124) about 1000$a year to about 100$ a year, so i can live with a slightly higher mileage cost

thanks for the help and info,

cheers!
