13 The transmission "dog" that the shifter lever rests in has a cap that requires two screws to be installed. Hand tighten the retaining cap screws, and you're ready to check the shifting action, which is always a good idea before buttoning it all up. Once the shifter is run through the paces and everything feels right, install the cover and you're ready to go. Did you fill the transmission? Now is the time to do a double check of all fasteners from top to bottom.
