I was just wondering if anyone can help me with my ml430 ive been working on for a couple months. When driving, a bunch of the dash lights pop up and eventually the check engine light pops up as well. The car will also be stuck in first gear and will not shift.

Ive tried many things with no success. Installed new conductor plate with the new plug thing that has the 2 o rings on it. Used an ohm reader for all 4 wheel speed sensors and they read ~1.07 each one which is pretty consistent. Im really running out of ideas and don't know what to do. I've seen a few threads on this same problem but the thread starter never comes back to let us know what was the cause of the problem. Any input would be greatly appreciated.
