Equipment Needed
***Always Use Proper Saftey Equipment***
1.) Mount Trans Cooler to car
Place trans cooler between the radiator and front bumper on the drivers' side. You'll notice notches cutout on the lower frame which will match up with the lower two screws of the trans cooler. You will have to drill at least one hole for the upper mount point, on some cars the 2nd hole may already line up. If not, drill a 2nd hole.

2.) Remove lower air dam
Remove the lower air dam using a 13mm socket wrench.

3.) Connect Trans lines to cooler
Use a 16mm open end wrench to connect the trans lines (supplied with kit) to the trans cooler and route them under the radiator. Thread sealing tape is reccomended to prevent leaks.

4.) Splice cooler lines into stock trans lines
Place a drain pan under the car. Take a pair of scissor or other cutting tool and cut on of the factory trans lines near where the new tranny cooler lines come out to. A little bit of trans fluid will leak out. Connect one of the new trans cooler lines to one end of the cut hose using the hose connectors and hose clamps ( I double clamped them to be sure they wouldn't leak). Now connect the other trans cooler line to the other end of the hose that was cut, using the same technique (hose connectors and hose clamps).

5.) Mount hose bracket (optional)
Mounting this bracket is optional, but offers a little more protection for the trans lines. Some cars may already have both holes below the radiator tapped for the bolts. There was only one hole on the '98 GTP that we tested this on. We *do not* reccomend drilling a second hole on a '98 GTP (and possibly other cars, drill at your own risk) due to the fact that the air conditioner condensor is DIRECTLY above the metal frame you are drilling into. If you choose to drill, be sure to note that the following disasterous situation may occur:
| Freon leaking out of a/c condensor from hole accidentally drilled into it |
6.) Cut lower air dam
Hold the air dam back up into position and note where the trans lines are preventing the air dam from being remounted. Take a dremel or key hole saw and cut out a small peice of the air dam to allow the trans lines to clear. Reinstall the air dam.

7.) Check for leaks
Double check all connections and make sure everything is tight (especially double check the spliced connections), and the transmission cooler is bolted down tightly. Start the engine. Check over all connections again and make sure nothing is leaking.
8.) Check transmission fluid level
After the car has reached operating temperature, shift the transmission into *ALL* (P, R, N, D, 3, 2, 1) gears, holding each gear for at least 5 seconds. When you get down to 1st gear, go all the way back up to P stopping at each gear for at least 5 seconds. On a level surface, pull the trans fluid dipstick (the red dipstick) and check fluid level. Refill fluid until full.
