Thank you for purchasing your new Speedtech Transmission Tunnel

your transmission. Take all necessary precautions whenever jacking
up your vehicle and be sure to use safe and sturdy jack stands to
support the vehicle whenever it is off the ground.

This Tunnel Cover can be installed with simple hand and power tools.
You will be required to drill some holes and cut a hole in the floor for
transmission clearance and a hole in the Tunnel Cover for the shifter.
Be sure to wear the proper protective gear when using power tools.
If you plan to weld the cover to the floor, be sure to take necessary
precautions when welding inside a vehicle to remove any close-by
flammable materials.Although not completely necessary, we have
found it easiest and safest to remove the carpet from the car to
perform this installation.

1.Find the final location for engine and transmission fitment within the
car's frame. Find and mark the shifter arm location on the
transmission tunnel on the interior of the car. Considering where the
shifter will be located, use your tunnel cover and mock up it’s location
on the interior of the car. Trace the outside of the tunnel cover and set

it aside. Then draw another line approximately 1 ½” to the inside of

the first line. These will be your cut lines. DO NOT cut at the outer
perimeter line.

2. Once the cut lines are laid out, take the necessary safety
precautions and carefully cut out the rectangular portion of the tunnel
within your marks. Test fit the transmission in place. Because of
model differences and factory tolerances further trimming may be
required. Be sure there is At least a small amount of clearance to
allow the drive train to flex without hitting the floor. The end result
should look something like this.

4. Next you will need to mark the Tunnel Cover for the shifter location
in relation to the cover's position on the transmission tunnel. Cut a
hole approximately 3.5” in diameter for the T-56 boot to fit through.
We recommend splitting and wrapping vacuum tubing around the
diameter of the hole to prevent gouging the shifter boot. Lay the
Tunnel Cover over the transmission. With a plastic mallet tap the
flanges down so that they mate up to the angle of the floor pan.
Reposition the shifter boot as necessary to seal off the round hole.
