do you know if the 114/115 inputs are the same as the 123 inputs?

I'm sorry, I miswrote that. The 115 and 123 inputs are the same, at least on the diesels.

The transmissions on my 115 & 123 parts cars are alike externally.

ok, thanks for that. So... i should be able to bolt up a 115 tranny to a w123 230e engine?

Has anyone actually done this?

R Leo, did you have to use a 300d manual flywheel or can you just use the flywheel from a 240d?

Does anyone know what lube goes into the early cast geaboxes? ATF or gear oil?

The three piece cast iron gearbox that is in my car is a '115'... at least that's what the casting numbers on the box say.

I don't know ANYTHING about Mercedes gasser engines so I'm not much help there. However, in the FSM I have for the 4spd manual tranny, I believe that the cast iron gearbox is shown bolted to a bellhousing with the starter wart on the right for the diesel and the left for the gas engine.

So, if your starter on your 230E is on the left side of the engine, I'm thinking that you'll need a gasser's manual bellhousing.

I used the 240D's flywheel. I'm not so sure that there's any difference in the 300D manual flywheel; there isn't much extra room in the bellhousing for anything.

Fluid:
The FSM says use ATF in the tranny. I use the same fluid that I use in the 300D's A/T: Dextron III

thanks, BTW whats "FSM"

I read someplace that the 300d flywheel was, I think, 7# heavier than the 240D one.

FSM=Factory Shop Manual

The FSM says not to use one with the other...

However, we have SEVERAL people on the forum who have and I have seen no posts of problems doing it...

300d manual flywheels are hard to find.....unless you are snooping around junkyards in Poland...

Or Bagdad, or practically anywhere else on the planet other than North America. And you might as well get the manual transmission that's attached to it while you're there.

HUM... I wonder how many there are in New Zealand and Australia..... you could ship them back next month...

And that's a damned good idea too. Kiwiland isn't an option (only 5 days there) but I'll bet there are plenty of manuals in NSW!!

where can you get the FSM for the manual transmissions?

I have one sitting on my kitchen table that grimgaunt loaned me. Have been thinking of scanning it, but the pics aren't great.

I have a question for you R Leo,
If you were going to charge someone to do all that work of swapping trannys, how much would that be?

It took me a long time to do the wagon because I didn't want to rush and then have to go back and rework things plus, I was learning as I went along.

But, knowing what I know now, I think I could do one of these swaps in 2-3 days fairly easily. So, applying the hourly rate of my day job to it, I'd guess I would charge something like $650 + parts (tranny, shifter, driveshaft mod and fluids).
