Swapping rear cover between 717.4XX transmissions
Swapping rear cover between 717.4XX transmissions
I've aquired a reasonably priced 717.417 5-speed out of a W202 C-Class. Now the thing is - it doesn't have any speedo drive.
I will probably have to fit the rear cover of a W124 5-spd. trans. (.411 or .412).
What I don't know - are the rear covers interchangeable?

Thanks a lot in advance!

Im wondering if that might be really complex, like the covers might work, but the newer 5-speed may not have a worm gear on the output shaft for a speedo cable.
Might be a major job to retrofit it back to a cable speedo, might be easier to grab a W202 speedometer gauge and wire that into your older dash than to retrofit the newer gearbox with something to drive a speedo cable

how does the speedo work on the 202 5-speed? is it a sensor?

I guess - but not on the gearbox... My guess is it uses one of the ABS sensors? As there's nothing on the gearbox itself.

All I need is a socket for the output flange nut...
Then I'd see if there is.(03-27-2012, 08:00 AM)dropnosky Might be a major job to retrofit it back to a cable speedo, might be easier to grab a W202 speedometer gauge and wire that into your older dash than to retrofit the newer gearbox with something to drive a speedo cable
The W202 has that awefull digital mile counter, though...
Thanks for your reply!
Looks like I'll just have to give it a go

Oh well, how quickly things can change. I'll keep you updated!

04-25-2012, 03:24 PM #11I will. Could be a while, though... I'm hopefully getting a W123 diesel 5-speed by tomorrow. But... My W124 200TE wagon could do with a 5-speed. If I don't swap that for a 250TD... Oh well, how quickly things can change. I'll keep you updated!

But by the looks of things I can use a auto-crossmember:
L to R: W123 4spd | W202 5spd | W123 5spd | W123/W115 auto

05-16-2012, 02:02 AM #15Number 6 arrived. This time a 717.435 from a 190E 2.6.
Question: is this for DM or SM flywheel??
(05-16-2012, 03:47 AM)aaa If you can see the tip of the shaft extending beyond the bellhousing, it would be single mass.
The shaft certainly islonger than the bellhousing. Hmmm... My W202 gearbox is the same - does this mean it's SMF too!? It's from a 1998 C180. But I thought the C180 got the DMF by 1996 too?? Hmm...
Thanks!
