Technical Manual for W114 280C Transmission - PeachParts Mercedes-Benz Forum

Does anyone have a Technical Manual for the automatic transmission in a W114 280C?

I need a diagram that shows an exploded view of how it comes apart/back together.

Thanks in advance!

That would be the "4-speed transmission" manual to 1977. It covers both the automatic and manual gear boxes. There is a separate manual for 1977+ models (the W123 cars).

My manuals are at my dad's house with the car, I can get them if no one else gets you the info first.

Jie.com has some exploded parts diagrams- not sure if yours is one of them

Good luck! The transmissions (yes, more than one) in my 114 have been nothing but trouble since I've had the car. I had a rebuilt unit put in the year before last, then later left it in the care of a friend back home (who drives like an old lady). Latest news-trans not shifting. I will never own another "4 bolt" Mercedes automatic.

There's a guy in Reno with a good idea. He pulled the original engine and trans and swapped in a 350 Chevy with a 700R4. The only trouble (according to his craigslist ads) is that he got sick and hasn't been able to finish it due to health. I think a 302 Ford with a T5 would be an even better idea.

But since you want to try to fix one of those evil contraptions, again I say good luck.

Why not keep the engine and get a 4 speed on the floor? there are millions from thoise cars.

I thought about that, but I found that it requires parts that are not obtainable (at least not at the junkyard rates I'm willing to pay) like a W111 flywheel or something. I'm dumping the car for cheap when I get back to the States.

Been there done that with my last w123 300D. At the time 4spd swaps were not common. The lack of man-trans put me back in Volvo's and BMW's for euro-RWD cars.

The auto in my 280 shifts well but is bearing-whiny to a large degree.

I passed up some of that stuff a month ago because I don't have a 280. There's a lot in New York and not that expensive. Expect to pay 100-150 and balance it yourself. You do have to look a little, but the stuff is there.
