Introduction
Note All wiring connections between components are shown exactly as they exist in the vehicles. It is important to realize, however, that no attempt has been made on the schematic to represent components and wiring as they physically appear on the vehicle. For example, a 4-foot length of wire is treated no differently in a schematic from one which is only a few inches long. Furthermore, to aid in understanding electrical (electronic) operation, wiring inside complicated components has been simplified.

Current Flow (1) Each cell normally starts with the component that powers the circuit, such as a fuse or the ignition switch. Current flow is shown from the power source at the top of the page to ground at the bottom of the page. In order to concentrate on the essential parts, power supply and ground connections are sometimes simplified by a dashed line in the schematics. A full representation of the power supply of a fuse or the power distribution from a fuse to various components is given in cell 13 “Power Distribution”. Full representation of the ground connections are shown in cell 10 “Grounds”. Switch Positions (2) Within the schematic, all switches, sensors and relays are shown “at rest” (as if the Ignition Switch were OFF). Splices (3) A dashed line indicates that the splice is not shown completely. A reference is given to the page where the splice appears in full. It is also listed in the Index.

Introduction Component Referencing (4) Each component on a schematic has a reference to the component location view or the page where it is shown completely. It is located to the right of each component. Component Names, Notes and Base Part Numbers (5) Component names are placed on the right hand side of each component. Any notes that describe switch positions or operating conditions follow the name. Descriptions of the internals of the component are also included here. The page where the component appears in full is listed in the Index. The base part number for a component is listed in parentheses next to or under a component. These part numbers will appear any place the component name appears in the publication. Internal Name and Function Identification Numbers (6) Some components on each page have internal symbols with an identification number located to the right. You can identify the internal symbol or function by finding the corresponding number under the component name. Circuit Function Identifiers (7) Some components without internal schematics use symbols or text to describe the function of a circuit in a system.

Connector Repair Procedures
Troubleshooting wiring harness and connector hidden concerns The following illustrations are known examples of wiring harness, splices and connectors that will create intermittent electrical concerns. The concerns are hidden and can only be discovered by a physical evaluation as shown in each illustration. NOTE: Several components, such as the ECM, utilize gold plated terminals in their connections to the wiring harness. If those terminals need to be replaced, they must be replaced with a gold plated terminal. Terminal not properly seated 1 = Locked terminal 2 = Male half 3 = Female half 4 = Seal 5 = Intermittent contact 6 = Unlocked terminal (Hidden by wire seal) 7 = Seal Check for unlocked terminals by pulling each wire at the end of the connector.

5R110 Transmission The intermediate (SSPC−C), low/reverse (SSPC−E), and overdrive (SSPC−B) clutches are each controlled by a directly proportional Variable Force Shift (VFS) solenoid. The coast (SSPC−A) and direct (SSPC−D) clutches are each controlled by an inversely proportional VFS solenoid. All shift pressure solenoids are electronically controlled by the PCM, which varies the current from 0 to 1 amp (directly proportional) or 1 to 0 amp (inversely proportional).

The Torque Converter Clutch (TCC) solenoid is a directly proportional Variable Force Shift (VFS) solenoid. The pressure output of this three−port device is proportional to the applied DC current supplied through an electronically controlled driver which varies the current from the PCM between 0 and 1 amp.

The Transmission Range (TR−P) sensor assembly is an internally mounted sensor, located next to the solenoid body, and includes the detent spring, rooster comb, and bracket. The sensor is non−adjustable and is serviced as an assembly. The sensor contains electronic circuitry that provides the PCM a fixed frequency at a duty cycle for each of the various positions of the manual lever (Park, Reverse, Neutral, etc.). The PCM uses the sensor signal for engine functions (start, reversing lamps) and for line pressure control, shift scheduling, and TCC operation.
