Transmission noise/shudder
My '77 240D with Auto trans shudders briefly but substantially in 2nd gear when accelerating. Mostly when going uphill or struggling a bit. It doesn't do it every time.
Is this a symptom of a bigger problem or is there a way to eliminate it? Thanks, Clemsnman |

you could try increasing the modulator pressure so the shift is a little more firm.....that might help
Are your flex discs, center carrier/bearing and transmission/engine mounts all in good shape? Those things being worn can cause a driveline shudder too.

Could be a vacuum problem...
My 1977 240D was plagued with vacuum problems.
The later W124 diesels had a separate vacuum pump under the rear seat for the door, fuel door and the trunk lock. The W123's used the engine vacuum pump for everything. My first thought would be to check the engine vacuum pump and see what kind of vacuum it's pulling. Are your door locks working quickly when locking and unlocking? If not, I would assume you have a vacuum leak somewhere. Lack of vacuum in a diesel usually causes hard shifts. You may be experiencing a minor leak... Hope this helps. The Tenor Man
