M.B. Special trans. fluid..
I remember my wife going to dealer to check on the taillight recall.
I asked her to see if they would check trans. fluid "pro bono" with the "special tool" (dipstick) outa curiousity..
Service writer told her she needed trans. service, car was at 50k miles then, he explained they used a special "electronic fluid"
O.K. guys heres the deal again. I have rebuilt many ZF transmissions, I do not profess to know everything, I just share my experience.
Heat and Friction causes wear and tear, which equals contaiminated fluid!! I have no idea where the phrase "sealed for life" came from? Or special fluid?
I have used mobile 1 synthetic & royal after rebuild. Worked fine!!
Recently It occured to me that the ZF trans. moving the Chrysler vehicles, in the Chrysler/Daimler company use +4, so I switched to that..
Why is it that the same transmission in another make of vehicle uses +4 but if its in a M.B. it needs the "special fluid" which costs about 4-6 times as much?? research it.........
If your transmission is working fine and you are doing a regular maintenance trans. service and you think it will cause it to fail? It won't!
Usually when someone is considering a service its because there is some problem with trans. and at that point its too late!! So when trans. fails after service, the service gets blamed....
Only problem I see is sealed converter after 99, You might think about drilling and tapping hole in it (8-10mm). Look at the plug on your hydralic jack where you add fluid and get one like that in metric. Its not rocket science.
Anyway my last post on this thread from hell.. This is just my opinion and experience..
