I’m not finding much that’s specific to the ‘96 E300 722.4 transmission.

I’ve inspected all the vacuum lines. No breaks or leaks...that can be easily detected. The transmission just doesn’t want to let go of each gear. When it DOES shift, it is a smooth shift. The problem is that I have to stay into the accelerator and wind it out to get it to shift. Letting off the accelerator does nothing to help it shift. Don’t even think about engaging the kick down switch! You’ll be up to 80 mph before it will ever let go and go into 4th hear. Low speed shifts are completely non existent.

I’m very familiar with adjusting the VCV and Bowden cable/pressure control cable on a w124 and a W126, but this w210 has an unfamiliar set up to me. Would appreciate some pointers from those who have experience with the ‘96 E300. Thanks! Kevin
