Question 280E manual trans--300D ?

You know what I'm thinking.. And what I'm going to ask..

I've searched and read, I know the 240D trans is the usual canidate for swaping into a 300D when it's done. I know most of the problems and work involved I believe.

Question is this.

Today I found hideing in the weeds at the local salvage yard, a 280E. Euro bumpers, round headlights, manual heat/air, and a STICK. This is the first w123 I've ever sat in, and the clutch and shifter(wood!) felt better than I would have expected, I could see driving the car. I could find no year on the emmesions tag underhood(or the tag at all for that matter), so I'm not sure what year it was, but it did have euro bumpers and a 5cyl gas engine.
Anyway, will that tranny bolt up to our favorite diesel? Is it the same as the 240D's? It was a 4speed near as I could tell, the shifter really felt pretty tight. Most importantly, is it worth haveing the trans and assorted parts for the conversion out of this car as oposed to the 240D? Any chance the driveshaft is the same length?

Dreaming of a real transmission.. Thank you for any input..

To my knowlage MB never made a 5cyl gas engine.

Only 4 or 6cyl gassers.
4,5 and 6cyl(w124) diesels.

Engine should be a Twin Cam 6 cylinder Gasoline (M110). The transmission will bolt up but the clutch and flywheel are different although many will probably tell you that it will work. Because the length of the 6 cylinder is about the same as the 5 cylinder diesel the driveshaft should be close enough to work.

I confess to knowing exactly squat about gasers, I thought I only counted 5 spark plugs, but it was definantly a twin OHC motor.

Anyway, it'd be nice if the driveshaft is close, but that's not a deal breaker really, they can be fixed if you find the right shop.

So, I'd need a clutch and flywheel from? 240D?

This is assuming I don't have the pilot bearing size problem I've read about, but I'll cross that bridge if I come to it, not like 300D's are rare I guess.

Wild guess, what would be a fair price for all the stuff off the car needed for the conversion, excluding the rear end? It was a fairly low mile car as I recall. 100K give or take, I was surprised how good the shift pattern still felt.

My take would be to rape and pillage that car ASAP! Take the tranny (if it's a good price, you can re-sell for more than you paid anyway) and take ALL the shift stuff, any wood inside that's good, the drivshafts (mark them both so you know how they came apart), take the pedal assy and clutch mast cyl (take pics and post here and I can tell you if they'll bolt to the 123). Just...., well...., take it ALL!

Reality Check

FYI-the 'feel' of the shifter on an W123 MBZ will have little to nothing to do with the actual operation of the tranny. All the shifter mechanisim and shifter bushings are inside the car, bolted on the hump.

The shifter I have for my conversion feels great too. However, it's sitting on the workbench, unconnected. I guess the jury will be out on my tranny till the swap is done.

That all said, if I were you, I'd offer them $50-$100 for 'everything' you need...flywheel, pedal assy, shifter, transmission, hydraulic lines...then once you get it, run like hell and get away before they figure out what you've done.
