DefenderWorx Mustang Automatic Gear Shifters User Manual

Thank you for the purchase of the Defenderworx Pistol Grip Shift Knob for
your 2010-2013 Mustang! You have made the decision to purchase a
finely crafted accessory manufactured right here in the USA. Our products
are officially licensed by Ford Motor Co. and made from T-6061 Aircraft
Grade Aluminum. There are a couple of notes we need to address prior to
beginning the installation process.

1. If your automatic Mustang is equipped with the option to have Sport
Mode or Manual Shift mode via a button on the shift knob, with the
Defenderworx knob, that feature will not be able to be used.

If you desire to maintain that feature, check back shortly as our engineers
are working with switch manufacturers to build a custom switch that will
plug right into your existing wire harness without having to do any splicing.
It is something that can be added at a later date without a lot of extra work

should you choose to keep the knob and install it on your vehicle. This

will not affect the performance of the vehicle or trigger any
dash lights should you choose to use the Pistol Grip knob.

2. This is rated as a medium to difficult level of installation. Not because
there is heavy lifting, but it is time consuming and deals with small
components. Length of time while doing instruction sheets was 1.5
hours. It could be a 2 hour installation at the worst case scenario

Defenderworx products are warranted for 4 years to the original purchaser

against manufacturer’s defects. We appreciate you choosing our product

and believe it is the finest accessory for Mustangs in the automotive
aftermarket today. We appreciate feedback and can also assist if there are
any installation questions. You can e-mail us back at

[e-mail]. You can call the tech line at 714.630.9700 M – F

8:30 A.M. – 4:30 P.M. PST.

Step 6: You now just need to reassemble the shift area back to stock

to remove your shift knob from the factory shaft. It is a quick tug and it

will unplug from the base of the factory shifter’s shaft. You are now able

to remove the factory shift knob and start putting your console back

without the factory shift knob. Once you have it all in place, you can add
the Defenderworx base to the factory shaft. Line the bottom of the base
up with your factory plastic liner and tighten the set screws with your
allen wrench.
