Steeda Tri-Ax Shifter Installation Instructions
For: 2011+ Mustangs w/ Getrag MT-82 Transmissions
Factory Shifter Removal:
1. Apply the parking brake and place the car in neutral. If you are not using a hoist, place chocks on both sides
of the rear wheels to prevent any possibility of the car rolling.
2. From inside the car, unthread the shifter knob.
3. Open the rear door of the center console and carefully unclip the center console cover from the center
console by prying up between the cover and bar. Gently lift up on the sides of the cover to unclip the rest
of the clips. There are around 6 clips securing the cover to the console. See figures 1 and 2.
Note: The leather shifter boot collar has two small FRAGILE plastic ears securing it
to the upper lever. Care MUST be taken to gently slide the collar up the lever
while lifting off the center console/shifter boot, or the ears will break
off!!!!!!!!!!!!!!!!!!!!
Note: Be sure to disconnect the electrical connectors for the traction control, and cupholder
illumination, if so equipped.
4. Set the center console aside, pull the sound deadening/insulating fabric over the shifter lever and fold it
back behind the shifter and rubber boot, out of the way. See figure 3
5. Carefully lift the rubber boot up and off the shifter lever, shifter base, and the floor pan to expose the
shifter assembly.
Note: Be sure to note how the boot fits on the upper lever, floor pan, and shifter base prior to
removal.
Note: Mark the boot’s orientation to the floor pan for re-installation purposes. The boot is not simply
round and must be oriented in place.
6. From under the car, remove the two 10mm nuts securing the rear shifter bushing and shifter assembly to
the floor pan. Lower the shifter assembly and gently pry the bushing from the rear of the shifter assembly
(noting its orientation) and set it aside. Allow the shifter assembly to rest on the driveshaft. See figure 4.
7. From back inside the car, remove the four 10mm head bolts securing the shifter mechanism to the shifter
base. Pull up on the shifter lever and remove the unit. See figure 5.
Note: Be careful not to tear or lose the thin gasket between the shifter and the shifter base.

Steeda Tri-Ax Shifter Installation:
8. Transfer the plastic cup attached to the bottom of the factory shifter lever onto the bottom of the
Tri-Ax lever, by carefully prying it off of the lower lever and snapping it onto the Tri-Ax lower lever.
See figure 6.
Note: Apply some general purpose grease to the inside of the cup before transferring it.
9. With the factory shifter base gasket set back in place, feed the Tri-Ax shifter assembly through the
floor pan and set it onto the factory base.
Note: Be sure the plastic cup, now attached to the Tri-Ax lower lever, is seated properly inside
the linkage rail.
10. Reinstall the four 10mm head bolts back into the shifter base.
Note: Before tightening the bolts, place the shifter in first gear and gently pull the upper lever
away from the reverse lockout ear on the base. Then finish tightening the bolts. There should
be around .02-.03 inches of clearance when in first and second gear. See figure 7.
11. From under the car, reinstall the rubber bushing back onto the base of the shifter and secure the
shifter assembly back into place with the two 10mm nuts you previously removed. Leave the nuts
loose with about half an inch of thread between the nut and floor pan for reinstalling the rubber
boot.
12. From inside the car, reinstall the rubber boot over the shifter and the floor pan.
Note: MAKE SURE the bottom hole of the rubber boot fits securely over lip on the shifter
bearing cage and the lip on the reverse lockout boss. It cannot just rest on top of the shifter.
Note: MAKE SURE the lips on the outside, around the middle of the rubber boot fit around the
hole in the floor pan.
Note: MAKE SURE the boot fits over the upper shifter lever just as it did with the factory shifter
lever.
13. From under the car, finish tightening the nuts for the rear bushing.
14. From inside the car, reinstall the insulation/sound deadening material back over the shifter and the
floor pan.
15. Place the center console cover back over the center console and reconnect any electrical connectors that
were disconnected.
16. Clip the center console back into place.
Note: Make sure all the clips snap back into place.
17. Reinstall the shift knob. You are done!!
Reverse Lockout Spring Replacement:
The design of the shifter allows for the amount of force required to shift the car into reverse to be changed. A small coil spring and several
preloading shims are now in the shifter. The provided spring has a higher spring rate than the spring installed in the shifter to allow more force to
be used to engage reverse. To change the spring, remove the set screw from the upper shifter lever, and push the pin behind the set screw out
through the set screw hole. You will need to insert a small tool into the 1/8 inch hole behind the pin to extract it through the set screw hole. Now
lift the upper lever from the lower lever and remove the spring and shims (they may still be in the bore of the upper lever). If the plastic sleeve is
still in the upper lever use your finger, or a small screwdriver, to gently pull it out. BE CAREFUL not to scratch the bore of the sleeve. Do not re-use
any of the shims currently in the shifter if you are going to use the higher rate spring. Be sure to install the upper lever in the correct orientation
and reinstall the pin and set screw into the lever. The pin must be fed through the slot in the lower lever to function properly.

The bottom potion of the boot must be
wrapped around the shifter base. See #1
This bottom lip must go through the
floor to the underside of the car, in
the trans tunnel.
This top lip must stay on top of the
trans tunnel and inside the car. This
provides the “seal” from the
exterior of the car and will eliminate
noise.
The top of the boot will fit tightly on the
machined grove on the upper portion of the
Steeda shift lever, see #2

This addendum is written for the addition of the necessary
spacers included for the 2013+ year model Mustangs.
Installation:
1. Make sure the factory shifter base gasket is set back in place, and install the provided shifter base
spacer onto the factory base. Feed the Tri-Ax shifter assembly through the floor pan and set it onto
the spacer.
Note: Be sure the plastic cup, now attached to the Tri-Ax lower lever, is seated properly
inside the linkage rail.
2. Install the provided 1/4-20 bolts into the shifter base.
Note: Before tightening these bolts, place the shifter in first gear and gently pull the upper
lever away from the reverse lockout ear on the base. Then finish tightening the bolts. There should
be around .02-.03 inches of clearance when in first and second gear. See figure 7 on original
instructions page 2.
3. From under the car, install the provided shifter base bushing spacer. Reinstall the rubber bushing back
onto the base of the shifter and secure the shifter assembly back into place with the two 10mm nuts
you previously removed. Leave the nuts loose with about half an inch of thread between the nut and
floor pan for reinstalling the rubber boot.
