Ok, I want to repair my odometer....used the paint can tools to get the instrument panel loose, undid speedo cable from clip at the foot well.... and can trace the cable to the transmission.

it seems like there is a plastic housing hold the speedo cable in. I simply don't know how to remove it to undo the cable.

I have a 1988 300e. The Mercedes manual says the speedo cable must be disconnected to remove the cluster. I agree.

I have searched 100 posts and most just say there is a 10mm bolt holding the cable to the tranny...like I said...I seem to have a plastic housing covering it.
