So Gilly, what's the recomendation on trans fluid change after a rebuild?
|
There is no specific recommendation that I am aware of, interesting question though. I know they test-run the transmissions in the factory on a test rig, so makes me wonder if some of the initial wear of the discs, if that stuff is flushed away on that rig, then the new stuff doesn't get all the graphite stuff in it so fast. I don't really thing that particular type of graphite material will hurt (and probably would actually help) the bearings. On a factory reman I'd just fill and forget.

I find it odd that once MB started to offer long term warranty's their cars went from requiring regular/routine/all encompassing service to needing essentially no service.

Yes, agreed. The whole filled for life idea is hard to get over. I know it will work if you are lucky,I just don't think the fluid change is going to change your luck, I personally know of a transmission (722.6)that was doing fine on the original fill of fluid at around 300,000 miles. I think this is abnormally high, but shows that it is possible to achieve high mileage on the filled for life concept.

Well, yeah a component that is in no way sealed like the transmission is. Take into account the fuel, combustion gases (blow by), ventilation air, etc and it's easy to see how the oil gets contaminated. What contaminates the transmission fluid is wear of the internal components of the transmission, and once the clearances are worn out of spec in the transmission, it's a slippery downhill slope. You can change the trans fluid and maybe extend the life of the trans, but if the clearances are out of spec the tranny won't be hanging around very long. If everything is working OK it'll be perfectly fine with the original fluid.
