On the early w124 are the manual transmissions interchangeable between the m103 (6 cylinders) and m102 (4 cylinders) engines? Looking to do a swap and just wanted to confirm before I make the investments.
Thanks
The boxes will bolt up to the bell housing without any problem. Likewise, no need to change out a flywheel. I would make sure the 4/5 SPD's are the same length and have identical flex disk flanges.
There are quite a number of threads on auto to manual conversions. It would be wise to use the search tool and just read over several.
I'm just going to assume you found a 190E 2.3 with a 5 speed.
Transmissions will interchange without a problem. You will need an M103 flywheel. You will need to find the correct driveshaft or take some measurements for a driveshaft shop to cut the center support flange off the W201 driveshaft and have the W124 one welded in place. That's something you'd see when you'd get in there
Thanks, I actually have a w124 te Euro model with a 2.3L and a manual 4 speed, yes I came across a 300e w a 5speed manual Trans and the 6cylinder engine. And before I invest in the second car I would like to know if they're bolt up material. I am mechanically inclined and have attacked worse swaps but don't want to modify too much. Thanks I will keep you posted in the results
I have an 88 300e with a 5 speed and it shifts better than most of the 80's bmw's that i have driven. Most 80's bmw shifter bushings have fallen out and the owners are to cheap to repair them.
I loved driving mine around the hills where i live until my son decided to play chicken with a big buck and took out the driver side of the car. I never thought a deer could do so much damage to a mercedes.
just do it you will love it:smile
Interestingly the stick shift 124s came to the U.S. only in 1986 and 1988. 86s were all 3.0s while 88s were 3.0s and 2.6s. I've owned one and driven a few others over the years. I thought they were pretty good and geared tall which I liked. But there was a Mercedes Buyers Guide popular years ago that referred to the shifter as "rubbery" as I recall and about a hundred people read that book for every person that actually drove one, so that perception prevailed. It was certainly a better stick shift than the U.S. 129 300SLs - which were a spectacular disappointment.
That is the same manual trans as the W124 version.
And to think that MB even had the balls to offer a stickshift in the W140 for the very first year, which nobody bought . . . even the Europeans. It's good to see them finally embrace 20th century tech (automatic transmission)
Great input from all. I was a bit nervous as I stated earlier, my w124 230te has the 4 speed manual and I am noticing some weird noises, instead of investing money in the rebuild, I figured I would invest in a 5 speed. Found several w201's but luckily I ran into a guy locally who has a whole 1986 w124 3.0L w/ 5 speed that he is willing to part. My hesitation was if I made the investment would the the 5 speed bolt up to my 2.3L without modification. But from what I'm gathering here , it seems like a safe bet to go forward with it. I don't mind the 4 speed manual but rebuilding it?? It may take some hunting to find the adequate parts. And being that the other is 5 speed, it is rare I didn't want to pass it up. What do you all say? Yay or nay? Go for the swap or the rebuild???
Admittedly, the only MB manual I have driven was a 1982 240D with the 4 speed, but I don't remember it being bad at all. A friend of mine had this conversation a few weeks ago, because I said that I wish I had a 5 speed in my 300D. I really wouldn't care if it were a bit rubbery anyway; I just want the ability to control the shifts, the added fuel mileage, and the extra power I would expect to get.
Speaking of w123 I came across some euro headlights if anyone is interested. A co worker of mine has several sets that he wants to part with. I will start a new thread for that.
Getting back to the Trans swap, I had considered dumping the entire engine in as well, but would rather dump a oil burner (diesel) in. I'm a fan of both. But this little 2.3L just purrs and is low mileage so I figured I would give it a try. My main concern was finding spare parts and the cost. Can any one point me to a reputable MB source that knows what they're talking about ( unlike to large web based sources). I am still pondering doing the rebuild but am having some difficulty finding out info on what I think may be a 716-217 transmission. 3rd gear has a whine and im not certain on the cost of I were to allocate the parts I could do it on my own. Just want to make sure I order the correct parts. I'm not planning on laying down 150mph passes just cruise it's a wagon after all.
Thanks, I was hoping that since the car has been parked for a number of years prior to me acquiring it recently, I would have some luck at a needle bearing or a roller that stiffened up on me, it would be worth a shot but not the time. If I'm dropping the Trans might as well do a swap or a rebuilt and a clutch. So I came across a part number for a Trans (716.217) seems to be the Trans number or model. I will do a bit more digging.
Looks like I may have to resort to that route. I'll will know more after I open up the Trans case and see what is in need of replacement. Thanks for the input, totally overlooked that option.
OR pick up the Euro grey market car with manual that was just posted a few hours ago. Pretty well equipped for a Euro spec car, other than wrong engine and trans for American folks. See link
Not a bad looking ride but I'm scared on what he will want for it. Let's just bidding on it and start low rhen work up the offers, I'll go first! I'll start @ $1k.... Lol. That looks to nice to just rip the Trans out
Well I couldn't pass it up, so I bought another w124, the wagon may have to wait a rebuild on the Trans. I will post you all when I open it up and shoot some pics of the 4 speed and the damage causing the unusual noise.
Sorry to thread jack, but can anyone tell me if there is anything specific about the shifter assemblies between Getrag and normal 5-spd? I'm buying a 717.404 and it comes with a shifter assembly but want to confirm it's the correct unit.
