– This document was
created in hopes of making installation of the Stillway shifter easier. 

– Please reference the
Stillway Shifter installation document (written in Japanese) when following
these instructions.



– When you open the
instruction booklet, page 1 details all of the parts necessary for
installation. Verify all components and proceed to page 2.



Diagram 1. This
details the shifter and begins preparation for removal of the shifter. Begin
by unscrewing the factory shifter.

Diagram 2. This
illustrates the cover that must be removed in order to loosen the bolt that
allows the shifter to be disconnected. 
This cover covers the bolt required to release the shifter from the

Note: When
jacking up the car, please take ever precaution to avoid injury. You will
need to have the car in neutral so, please double check the emergency brake. 
Also, a flashlight is recommended to view the necessary components.

Diagram 3. The
bolt to be removed faces the rear of the car. 
There are two bolts, be sure to only disconnect the bolt, which is on
the right in the picture.  You
will need a 9/16th socket to remove this bolt.

Diagram 4. Remove
the leather cover from the shifter.  Remove
the ashtray, open the leather cover, which attaches to the shifter and
remove the plastic piece.



Diagram 5. With
a 10mm socket, unbolt the metallic metal cover form the bottom of the
shifter.  This piece helps in
keeping moisture and noise from entering the driver’s area.

Diagram 6. Now,
carefully remove the metal cover then, the rubber boot.

Diagram 7. More
detail on removing the rubber boot.

Diagram 8. Using
the 10mm socket, remove the metallic plate. 
Note the position of the plate before removing it! 
This will give you an idea of how the sequential shifter works.


Diagram 1. Remove
the metal pin that holds the factory plastic ring on the shifter. 
Basically, this piece should push out. 
Be very careful not to damage any of the plastic pieces inside the
plastic ring.  Personally, I cut
mine off making it easier.  You
will not need this piece later on. 

by cutting the plastic piece, you must use the sequential shifter, Toyota
does not sell this separately, and you will need to purchase a new shifter
if you decide not to use the sequential shifter.

Diagram 2. Upon
removal of the plastic ring, be sure to replace the plastic inside guide
exactly how it was inserted.  Be
careful not to damage this plastic piece!

Diagram 1. Take
the metallic piece and place it on the shifter. 
Carefully note the position of the hole be, sure to position this
exactly how it is pictured in the diagram. 

Diagram 2. After
the metallic piece is placed on the shifter, use the metal wedge provided to
secure the piece.  Make sure
that the wedge is perfectly centered and not sticking out on either side.



Diagram 1. Place
the shifter back into the proper position. 
Be sure not to place the shifter on backwards!

***Diagram 2. Ok,
now for the important part!  There
are two guides; the left guide has an angle built in. 
The right guide has a square shape. 
The guide with the angle should be positioned on the left such that
the angle directs the shifter towards the 3rd gear gate. 
Carefully study the #2 diagram on page 5. When the shifter is in the
center position, each guide should slightly touch the square piece on the
shifter. Now, these pieces should prevent the shifter from moving left and
right and guide the shifter into 3rd then back to 4th. 
Basically, in this position, you should only be able to move the
shifter into 3rd and 4th gear. Make sure the shifter
cannot be moved left and right, do not allow play yet, allow the shifter to
be moved from 3rd to fourth smoothly. Tighten the angled guide
securely and be careful not to strip the bolts! 
Then, place a washer on the left bottom bolt. There are two bolts,
one towards the front of the car and one towards the rear, place the washer
on the bolt that connects to the rear bolt. 
The reason I did this was to allow easier shifting into 6th
gear. In order to go into reverse, the shifter will be moved to the far
right and then back.  So, when
you drive the car, be sure to be very careful not to over shift into

Diagram 3. This
describes how the shifter should easily move from 3rd to 4th
gear and not from left to right.  Notice
how once the shifter is between the gates, it will guide you into 3rd
then, into 4th gear…very nice ehe?!

Diagram 4. Take
the metal ring and place it on the shifter as shown in the diagram. 
Then, place the C clamp so that the ring will be secured.



Diagram 5.
First, secure the shifter onto the transmission carefully! 
Reconnect the bolt that connects the shifter to the fork. Then, place
the rubber cover back over the bolt. The kit comes with 4 rings and
instructions. On my car, I did not use these rings. 
My car is a 1997 so; these may not be required on other year Supras.

the new shifter on gently and position the hole on the shifter so that the
small allen bolt will screw in the “L” guide on the metal ring.

the shifter so that when the ring is turned into “normal driving mode”
every gear can be reached.  There
are two modes, the first is normal mode, basically lift up on the ring and
turn so that the allen bolt locks and holds the ring in an up position
allowing all shifts to occur normally. 
Once the shifter is at the proper height, use the bolt provided to
secure the height.  On mine, the
allen bolt faces towards the back of the car…use this as a guide to
getting it adjusted properly.  Of
course, every car will be different.

to engage sequential mode, put the car in first gear and turn the ring so
that the ring drops.  What will
happen is, 1st gear will shift into 2nd as normal. 
Then, as you shift into 3rd, the guide will set the
shifter into 3rd gear…hence reducing the number of missed
gears!  Then, the guide will
guide you into 4th gear. Notice in this mode that you shifter
cannot be moved from left to right. To get it back into normal mode, lift up
on the ring and turn to lock into normal position.  

all steps are complete, take the car for a spin and make sure all gears are
smooth.  Some adjustment may be
necessary.  Note that the shifts
will feel a bit shorter and will take a little getting used to. 
From neutral into first, you may need to angle the shifter towards 1st. 
This is normal, the gates are designed to guide all shifts more
efficiently. However, no grinding should occur! 
If your car grinds, adjust the unit so that the height is correct. 
Once you have finished testing the unit, replace the rubber boot and
the metal cover that secures the boot. 
Then, place the plastic cover and secure the leather to the shifter
allowing the ring to move properly.  Replace
the ashtray and you’re done!

practice with the unit in a parking lot. 

hope this helps! Enjoy the unit and I’ll see you at the races!
