NOTE: Do not bend the manual valve rod clip when installing the manual valve rod. If the manual valve rod clip is bent back to install the manual valve rod instead of sliding it off, the manual valve rod clip will become permanently distorted causing total loss of transmission control or transmission failure. If the manual valve rod clip is bent, install a new manual valve rod clip.

Install the manual valve rod in the manual valve and the TR sensor and move the manual valve rod clip over the manual valve rod until the manual valve rod clip tab goes through the TR sensor to hold the manual valve rod in place.
