My wifes 1990 300E is loosing reverse. The trans work great in Drive . But is slipping in reverse and will kinda knocks/chatters when it finaly starts to move in reverse. The car has 190,000 miles on it with out many flaws.
Any Ideas? I have check the fluid level. It is ok. Before I notice the slippage, I change the Flex disk thinking that was the chatter, old one was shot.
