HI, Ive got a 1986 300sdl that I have fixed some vaccum lines on and changed transmission fluid in. Transmission shifts perfectly in all gears when cold but after driving awhile it gets stuck in either 2nd or 3rd gear. Most of the time shifting it back into N and back to drive will get it to upshift back to 4th. Would like to know what to look at and how to test. I have 5in vaccum at transmission at an idle. Any help Please and thanks.
I unthinkingly started to unscrew the shifting linkage on top of the valve cover before removing the valve cover for adjustments. (1st time on OM617 engine) I quickly realized my folly but too late. All is back together but shifting is quite out of whack! How do you properly adjust that? I have tried to return it to where the "dirty" part of the linkage meets the connection. That made it work better, but initial startup from a stop is painfully SLOW! TIA for all your helpful responses!

Through a local dealership I purchased a red modulator for my vehicle.
When I removed the old one I saw that it had a dowl attached to it. I attempted to remove it, but it seems to be part of the modulator. The new one does not have this. Is it a design change, or do I need another part.
Just replaced and tryed adjusting rear brake shoe assembly with new rotors...Now, the car does not back up or feels like it is rolling up onto something. Not sure if I adjusted the star gear properly. I know there is a balance, but this is getting frustrating. The E-Brake pedal inside the car does not get enough resistant/stiff when pedal is pushed down. It releases fine/quick.
My '87 300SDL shifts very hard between 1st and 2nd. Since replacing the vacuum modulator, the rest of the gears are fine. However, a few days ago after the car sits for a few hours it does not like to shift out of 2nd. After driving at a maximum of ~45 MPH, if I come to a stop and start over it upshifts to 3rd and 4th fairly smooth. Is there an easy fix, or am I looking at rebuilding the transmission?
Are all steering boxes for the W124 chassis interchangable? What are the limitations to swapping if there are any?
To be specific, I have a 1992 300D 2.5 Turbo with a far-too-far-gone steering box and not much money to fix it. So I'm trying to figure out how wide I can cast my net at the ol' pick-a-part, so to speak.
Have a newly acquired 79 300sd w116 - Looking for help/ advise on procedure to remove and replace the steering coupler assy. - this is the metal coupler with 2 Hex head bolts clamping onto the stering column shaft on 1 side & Steering Box on the other.
Do I
a) loosen pull out the steering column shaft via the inside steering column / wheel assy inside
b) Loosen - drop the steering box assy
Has anyone done this that can advise on the best way.
I help a friend maintain her 1983 300TDT, and it is due for a transmission fluid & filter change. It has very recently been slipping when in "D" on an incline, such as at a stop sign at the top of a hill. It will just start rolling back. I will be changing the fluid & filter, and plan on using the Lucas additive as well. She has recently taken it to a couple different shops for some work to be done, and someone had apparently overfilled the transmission. I took out the excess with my mity-vac, but the performance remained the same.
My question is this:
What is your opinion of transmission flushes for these older MB auto trannies?
I changed the transmission fluid and the filter 300 miles ago; lately, when I start driving, the car seems to stay in first gear too long and then suddenly jump into second gear; it makes the rear wheels chirp;
it then shifts quickly from third gear to fourth gear.
I am looking at the following:
1x 616 617 Diesel Transmission Vacuum Shift Valve Dashpot Upgrade $10.85
1x Diesel Automatic Transmission Peak Performance Tuning - NEW MANUAL RELEASE
Can you help?
I'm replacing the front rotors on my 1978 450SEL this coming weekend and after a quick glance at the front rotor it looks like you need to remove the entire hub on these to replace rotors. I looked for a tutorial covering this but could find one.
If this is the case do you have any gotchas I should be aware of?
Thanks!
