Early units had plenty of quality problems. If you look at the troubleshhooting chart in the diagnostic manual from Mercedes for this tranny, it's amazing to see how many problems have a possible cause listed as being a loose or missing screw that is internal to the transmission.
I've read that these problems only affected the first few months of the '96 model-year. I've also read where they continued into '97...

) Cause of failure turns out to be failed sprag gear. (one way gear that now goes both ways) this tore up a drum and sent metal through the system. computer put trans in "high pressure" mode, causing hard shifts.This trans is BIGGER than the one in my 4wheel drive truck! Huge compared to most others.
