Why are TRANSMISSIONS so damn hard to diagnose ?
Hey.
1983 240d 186k My problem came back again from a silky smooth transmission. I fixed it a few weeks ago but now I'm at the point where I'm about to buy another cream puff but in MANUAL. I've yet to take this car to any type of mechanic so if you know of someone good in New Jersey please post away. Anyway.... I'm getting rough shift from first to second so I would love to diagnose the problem. (it's not that bad but rather annoying) I've been planning on keeping this car for years since the body is so perfect and shiny (I bought it from the original owner which has garage kept it all its life). I thought about manual conversion but my father is telling me that there is too much involved in such a conversion (what does he know?). I have a 240D manual sitting around my house for 500 bucks and the car has 176k. Should I try to fix the vacuum somewhere ? Take it to a mechanic ? Or just buy another nice 240 ? (money is not an issue at all) Thanks

Because each one is different. ![]() Because it is not a steady state machine. Because it uses multiple command controls. Because each OEM thinks that reinventing the wheel on every transmission is good. ![]() Because the nut behind every steering wheel is different. ![]() ![]()

I've had unusualy crapy luck with MB auto's myself. Any old C4 or 6, 727, TH-whatever, even the 700R4's, I can get em to do what they should and they seem to last just fine with practicaly no maintanance, and forever if they do get regular fluid/filter jobs. But this MB piece, jeez.... I mean, the variation I get with mine just from fluid temp ALONE is crazy. I've never seen it to a degree that anyone other than a mechanic would notice with a *normal* auto. Anyway..

As per previous posts, on other forums and clubs,
It seems that a little ruff shifting is better for the MB tranny. I was lead to believe that a soft shift is bad for them. But then again I could be wrong. Louis. |

I had the same problem. Fixed a leak in the door lock vacuum system, then my transmission started shifting smoothly.

Mine is in the shop now. I did not have time to diagnose myself. The trans guy says there is a vacuum distribution pod located on the rear of the IP, and that mine seemd to be leaking. I will be talkinbg to him, later today and will update.
Many MBZ trans problems are due to vacuum problems. Joe.
