The MOMO Automatico shift knob is built specifically for automatic transmissions that use a button to release the shift lever from park. It's available in a satin aluminum finish or black leather, both finished with a chrome release button, chrome ring inserts around the base, and a chrome collar. Important Compatibility Information This knob's built-in button mechanically releases the shift lever from park. It is intended for automatic transmissions whose factory shifter uses a push-button park release at this location; it will not function correctly on a shifter that doesn't use this release style. Features Chrome release button for park lockout Chrome ring inserts around the base and a chrome collar Available in satin aluminum or black leather Installation Notes Like MOMO's other shift knobs, this is a universal, non-threaded design that mounts with set screws rather than a thread adapter.

This knob's chrome button is built to release the shift lever from park, so it is designed for transmissions that already use a button-release mechanism at that spot. What if my automatic shifter doesn't have a button release?If your factory shifter releases from park a different way, this specific knob won't function as intended. MOMO's Ultra shift knob is a non-button option if you just want a manual-style knob on an automatic that doesn't need the release mechanism. What finishes are available?Satin aluminum or black leather, both with chrome trim and a chrome release button.
