240D Gearing
240D Gearing

This weekend pulled a OM616 with 4 speed manual transmission for a conversion into a 450SL.
We got the shifter assembly for the 4 speed, driveshaft, and petal assembly.
We have a 300D parts car, but if the 240D has different gearing, we still have time to pull the diff out before the vehicle gets crushed.
Looks like the 123 diff will fit right into the 107 chassis of the 450SL.

Thanks.. just wanted to know before the 240D is crushed.
Do you have the diff ratio of the 450SL?

(08-31-2015, 06:54 AM)Petar @OM616 you might as well go with a 5 speed or even a 6 speed since you're going through all that trouble anyway
The real trouble is finding a good 5 or 6 speed in the US without having to take out a 2nd mortgage. 4 speeds are what are available in the junkyard. Can I get an amen?

Amen Brother!! lol
Plus the rear end gear should be fine with a 4 speed as it has a 4 speed auto now. I have not compared the gear ratios yet, but this is not a race car. I just want something simple and reliable with as little effort as possible and without breaking the bank.
I have a similar job in process now for others, mating a Getrag 420G to a M117 aloy, and M119 blocks.
I can get a 4 speed and all the parts for under 200 bucks. Just need to pick a clutch, make a flywheel, and mod an auto bell housing, everything else is Chicken XXXX lol

My main reason for posting was to try and find out how it did. I bet it will be find as long as I am not popping the clutch lol... I have known them survive 200HP Diesels very aggressively driven, but they were in lighter cars too...
I would use an early model iron case trans, but it would be interesting to know what it was actually rated for.

larsalan I guess I need to look at this stupid ass drip shit. What you have to like mess with those elements on the pump? What a fucking hassle. then use some wire to hold the throttle open or some shit?
Simpler=Better
09-01-2015, 09:52 AM #13Don't sweat the clutch/trans, trust your gut. If you don't slam it it will last a while. Case study: me using my 2.5L light clutch/transmission like most people use a fullsize...made it to 238k
