Most transmissions have a test port that connects directly to the sensor. On some, you will need to drill and tap a
hole.
7.3.1 Typical Installation
Select a location to attach the sensor, preferably a pan bolt. If you have a stock pan with a lip around the edge, you
will need to use the spacer. If you have a cast aluminum pan (as shown in photo), you might not. Plan to route the
wire and hose away from exhaust heat.
Connect the hose to the pressure port on your transmission (you may need a 90-degree fitting, not supplied).
Remove the stock pan bolt. Using the provided bolt, install the clamp holding the sensor. Add the spacer between
the clamp and the pan if needed.
Connect the cable to the sensor and its other end to the TRANS 2 socket on the COMPUSHIFT II controller.
Be sure to check for leaks.
7.3.2 ZF4HP24
The ZF4HP24 does not have a 1/8" pipe threaded line pressure port. It needs an adapter. An easy way to make this
adapter is to drill and tap the existing port plug.
First, locate the plug on the front pump assembly. Looking from the front of the transmission, the line pressure port
is located at about the 4 o'clock position.
