I was looking on www.mercedesshop.com for any trans info.Sure enough a chrysler tech was on there asking the mercedes techs about 6 speeds popping out of gear! One of the mercedes techs said there was a tsb on that problem in 2002.The 1 to 2 synchronizer assemblies weren't put together right and this would cause the popping out of gear.He said MB has misassembled many of these synchro. assemblies.I figured it would be a screw up at the assembly plant and would only pertain to a few cars.It seems to happen to cars with low miles only. I'm not sure how chrysler will handle this problem....fix trans or replace trans.You will have to get your dealer to duplicate the problem first.
