Go to SP Motorsports and get yourself a 5/16"
Autometer Trans Temp Manifold.
You can install this like I did, but you've got to be extremely careful in your measurements,
cause this will come really close to your lower radiator hose.
I installed my temp sensor so that I could read the ATF oil temperature
after it leaves the tranny, but before it enters the radiator cooler.
This temp reading coincides with the same reading you will get using a scan tool and looking up the TFT value.
(Transmission Fluid Temperature)
Only cut the ATX oil cooling line using a pipe cutter.
Do NOT use a hacksaw or a jig saw.
You will introduce metal shavings inside the pipe, or you will bend the pipe out of round.
Follow the ATX Cooler line from the top of the rRadiator back to the transmission.
Crack the fitting at the radiator and remove the line.
Crack the fitting at the transmission and remove the line from the vehicle.
Following the directions that come with the manifold, you want to leave about 1/2" - 1" of pipe
between where you cut the pipe, and the elbow behind the nipple that fits into the radiator cooler.
Mark where you are going to make your upper cut into the pipe,
mark where you are going to make your lower cut into the pipe based on the manifold's directions.
Fit the temp sensor into the manifold using teflon tape to seal the threads.
Fit the couplings into the manifold using teflon tape.
Now using a bolt and nut that will fit all the way through one of the mounting holes on the manifold.
You want to anchor about a 3' section of wire using a terminal that fits over the head of the bolt.
This is going to become your ground strap for the sensor.
Since the ATX Cooler Lines are not all pipe, the portion of the pipe that attaches
to the radiator is isolated from the vehicle and not grounded.
Attach the compression fittings to the cooler lines and assemble the lines to the manifold.
Make sure that you position the pipes as close to their original positions as possible.
They don't have to be exact, you can alwasy bend the pipes a little to get them into the correct position.
Attach one end of the wire you are running from the sensor to the gauge,
at the sensor, also using a terminal that fits over the bolt.
Reinstall the cooling line.
(When I reinstalled my line, a corner of the manifold was pressing against my lower radiator hose.
I had to remove the cooler line and use a Dremel to cut enough material
off the corner of the manifold block so that it would not touch the lower hose.)
Attach the sensor wire to the gauge.
Cut accordingly and attach the ground strap to a ground point on the radiator support just behind the headlamps.
You will see about two or three black wires that are all attached to the support,
just behind the passenger headlamp, on the engine compartment side of the radiator support.
I used this point to anchor the ground strap.
That's it! Check the oil level of your transmission.
You will lose some oil when you remove the line, but it shouldn't be more than 1/2 quart.
