Hotchkis 2278 2004-2006 GTO Sport Sway Bars - Manual (Page 4)

You will notice that the hard transmission lines lay on top of the coolant/transmission line bracket mounts.
Make sure to move the transmission lines below
the brackets. This will allow the bar to pass through
between the coolant lines on top and the transmission lines on the bottom.
8) This next step is where the messy stuff begins. As you can see from looking at the stock sway bar location,
the bar will not be able to slide out while the transmission lines are connected. It will be required to
disconnect the soft hoses from the hard lines. There are 2 lines that will need to be disconnected and
blocked/plugged temporarily. To avoid spilling too much transmission fluid, use some hose pinch-off pliers
to seal one soft hose at a time. Prepare yourself with your 3/8” hose and 7/16” bolts. Use the other hose
pinch-off pliers to clamp down the center of the 3/8” hose. Loosen the hose clamp using a 6mm socket.
