The proceedure requires the use of the Super Star or New Generation Star tester to go into adjustment properly, below is the info you are looking for.
NOTE: To check the FIPL sensor for proper operation and to make any adjustments the engine MUST be turned off.
NOTE: The throttle must be held to the floor, during Key-On, Engine-Off On-Board Diagnostics until the codes have begun to issue from the STAR Tester Transmission Control.
NOTE: The STAR Tester remains in the adjustment mode for only ten minutes. Steps 3-5 must be completed within this time period. If the ten minute time limit is exceeded this procedure must be repeated from Step 1.
NOTE: The FIPL sensor bracket is permanently attached to the pump with tamper-proof screws. Movement of the bracket is not intended as a means for adjustment. If required, adjustment of the FIPL sensor may be accomplished by utilizing the clearance between the sensor to bracket screws and the sensor. If the FIPL sensor bracket is loose, remove the epoxy from the bracket to pump mounting screws, adjust the FIPL sensor/bracket assembly to obtain a steady tone, retighten the screws, and reapply epoxy to the screw heads
