Transmission issues on '77 300D

the battery died on my 300d. I had my father-in-law pull my 300d home with my F250 (with tow-strap) about 7 miles. I put the 300D in neutral (AT) and about 1/3 the way there, the speedo cable broke. I finally got it running and now the auto tranny seems to be slipping a little bit from going 1st to 2nd, and from 2nd to 3rd. Any thoughts/suggestions? I'm ordering an "Early Auto Tranny service kit (1)" from you guys anyways. Any advice on the speedo cable? I'm using my GPS for now to tell me how fast I'm going. Thanks!

115 front seat belt issue.

Hi all I'm in a bit of a fix with the local car authorities. I currently have 2-point seatbelts in my W115 (one near the shoulder, the other in the middle of the bench seat). They are saying that I can fix a 3-point seat belt in my W115 and consequently refused to let me renew my license until I change it. My mechanic though is saying there is no where to bolt the third point (somewhere under the shoulder). Can anyone confirm which of the two is right? Mark

Vacumum lines have oil

I have a 1980 123 300D non turbo, shut down was acting slightly slow after testing nothing appears to be leaking and pump is producing a strong 23psi, upon testing fuel shutoff valve it shut off under two pumps from mitivac, after testing and re-connecting shut down is excellent but lines are coated with oil. so 2 questions here: 1) is there any way to clean out the hard lines without completely replacing and only replacing the rubber connectors?

Which manual transmission fluid?

OK, I am working on fixing up my old 1983 240D, I was thinking about changing the manual transmission oil, due to the fact that I have no idea if its ever been done. What type of fluid can be used? The manual I have says Type A automatic trans fluid, which I don't remember seeing in the stores. I saw a listing on ths site for 2 liters synthetic of gear oil. Is that compatable? Even though the manual says ATF type A? Thanks for your help!

SPEEDOMETER/ODOMETER FAILURE ON 76 300D

THE ODOMETER AND SPEEDOMETER RECENTLY QUIT WORKING ON MY BENZ. RIGHT BEFORE IT COMPLETELY QUIT, I NOTICED THE NEEDLE FOR THE SPEEDOMETER BOUNCED AROUND ALot, then...nothing. some of the lights, such as glow plug, brake sensor and battery lights still work, but the regular illuminary dash lights do not. I replaced the bulbs, but still no light. Also the old becker radio did not work and i pulled it out, but can't seem to figure out what config. to hook up a cd player. could the radio issue be related to the failures on the instrument cluster?

350SD: Car shakes heavily at low idle once warmed up.

Hi, My wife has a 350SD (W126 - 1991) with 146k miles. We have had it only for the last 15k miles or so. The car has developed a strong throbbing, low frequency vibration or shaking (the whole car) when stopped at a stop light (for example) after it has been driven for a while and is well warmed up. It is slightly noticeable, but much less severe, when started up from cold. Otherwise, the engine seems to run smoothly and be OK at higher RPMs. I have noticed that the idle speed drops a little from, >6500 to

starting problem

I have a 76 300D that I am having a strange problem with. Usually the car will start without any problem two or three times, and then it will appear that the battery is too weak to even make the car turn over, although the headlights and other electronics still seem to be at full power. I have had the alternater tested and it seems to be working fine. I took the battery back to Wal-Mart and their machine (as well as AutoZones) found the battery to be good.
