When was the 722.6 sorted out?
Someone aked me this question, and I don't know the answer. I know that 1997 and 1998 model years have some problems with 722.6 five speeds, but I am not sure if 1999's are also experiencing some difficulties. I think in 2000 they switched to the touch-shift style shifter and that there are tranny upgrades that came with it.
Someone was looking at a used 99 E320 wagon and I can't think of any potential problems other than the crank balancer and usual W210 interior bits.
