My 2003 Mercedes C220 has been tested positive for glycol in transmission oil by my local MB dealer. They say it's low range and submitted the Eskulab (goodwill) application to MB Maastricht. There's a small amount of goodwill on the parts but it will still cost me the earth to have the repair done by the dealer. My key issue at the moment is that the repair MB recommends is replacement of radiator, torque converter and flushing the gearbox. I've spoken to a couple of independent transmission specialists who know the problem well. Both have concerns about leaving the existing gearbox untreated. These are that that the flush would still leave a quantity of contaminated oil (approx 4 litres they say) in the gearbox that would immediately start to compromise the new torque converter, the teflon and rubber components will have swollen by the action of water, the clutch frictions would be contaminated and will be lifting etc etc. This is all BS according to the MB dealer for the level of glycol in there. But I wonder if MB won't publicly recognise the broader issue because adding gearbox replacement/rebuild to the job would give customers a heart attack! As I say there is a small amount of goodwill forthcoming on parts if I have the job done by the MB dealer, but my concern is that to take advantage of it would result in a future problem though having an incomplete job done. In around 10K miles both specialists say! Anyone have any experience/knowledge that would shed some light?
