Shifting bracket?

At the top left of the trans is the sensor held in by 2 7/16 bolts and a harness acessible from the engine bay area.

No need to remove anything else

The crankshaft position sensor is mounted to the transmission bell housing at the left/rear side of the engine block. The sensor is adjustable and is attached with one bolt. A wire shield/router is attached to the sensor.

REMOVAL

Disconnect sensor pigtail harness (3-way connector) from main engine wiring harness. This connection is made near rear of distributor.
Remove sensor mounting bolt.
Remove wire shield and sensor.
INSTALLATION
With automatic transmission: New replacement sensors will be equipped with a paper spacer glued to bottom of sensor. If installing (returning) a used sensor to vehicle, a new paper spacer must be installed to bottom of sensor. This spacer will be ground off the first time engine is started. If spacer is not used, sensor will be broken the first time engine is started.

New Sensors: Be sure paper spacer is installed to bottom of sensor. If not, obtain spacer PN05252229.
Used Sensors: Clean bottom of sensor and install spacer PN05252229.
Install sensor into transmission bellhousing hole.
Position sensor wire shield to sensor.
Push sensor against flywheel/drive plate. With sensor pushed against flywheel/drive plate, tighten mounting bolt to 7 N.M (60 in. Lbs.) Torque.
Route sensor wiring harness into wire shield.
Connect sensor pigtail harness electrical connector to main wiring harness

right from alldata. I have done hundreds of them.
