System Operation

The PCM and its input/output network controls shift timing and line pressure (shift feel).

The transmission control strategy is separate from the engine control strategy in the PCM , although some of the input signals are shared. When determining the best operating strategy for transmission operation, the PCM uses input information from engine and driver related sensors and switches.

In addition, the PCM receives input signals from transmission related sensors and switches and uses these signals to determine transmission operating strategy.

Using all of these input signals, the PCM can determine when the time and conditions are right for a shift or when to apply or release the TCC . It also determines the best line pressure to optimize shift engagement feel. To accomplish this, the PCM uses output solenoids to control transmission operation.

Component Description

Sensors and Switches

The PCM controls the transmission electronic functions through input signals received from the engine and transmission sensors. The PCM uses these inputs to control line pressure, shift time, TCC and shift solenoids.

Item Description
TFT sensor This sensor is located in the main control. It is a temperature-sensitive device called a thermistor. The resistance value of the TFT sensor varies with temperature change. The PCM monitors the voltage across the TFT sensor to determine the temperature of the transmission fluid. The PCM uses this initial signal to determine whether a cold start shift schedule is necessary. The cold start shift schedule allows delayed shifts when the transmission fluid is cold to help warm the transmission fluid. The PCM also inhibits TCC operation at low transmission fluid temperatures and adjusts line pressure for temperature.
TR sensor The park by wire dual range TR sensor indicates the state of the park system. The cable shift dual range TR sensor determines the customer selected shifter position.
TSS/ISSA (Turbine Shaft Speed/Intermediate Shaft Speed Assembly) sensor The TSS/ISSA (Turbine Shaft Speed/Intermediate Shaft Speed Assembly) sensor is a Hall-effect type sensor that provides a turbine shaft or intermediate shaft speed signal to the PCM . The TSS (Turbine Shaft Speed) signal changes in frequency as the rotating speed of the trigger wheel, part of the B clutch cylinder, varies. The ISSA (Intermediate Shaft Speed Assembly) reads off of the reaction sun gear and is part of the TSS (Turbine Shaft Speed) sensor. The TSS/ISSA (Turbine Shaft Speed/Intermediate Shaft Speed Assembly) information is compared to engine rpm to determine TSS/ISSA (Turbine Shaft Speed/Intermediate Shaft Speed Assembly) performance. TSS/ISSA (Turbine Shaft Speed/Intermediate Shaft Speed Assembly) is also compared to the OSS to determine shift quality and clutch performance.
OSS sensor The OSS sensor is a Hall-effect type sensor that provides an OSS signal to the PCM . The OSS signal changes in frequency as the rotating speed of the trigger wheel, part of the park gear, varies. The OSS is used for shift scheduling. The OSS is also compared to the TSS/ISSA (Turbine Shaft Speed/Intermediate Shaft Speed Assembly) to determine shift quality and clutch performance.
Transmission Fluid Pressure (TFP) sensor Transmission Fluid Pressure (TFP) sensors for clutch A (TFP A) and B (TFP B) have been added to improve diagnostic capability for non-electrical (stuck solenoid or valve) faults. Pressure readings are used to monitor the status of specified clutch systems during operation.

Solenoid Body

Solenoids

Item Description
1 TCC solenoid (7G136)
2 Retainer (7H186)
3 Bolt (W712658)
4 SSE solenoid (7J136)
5 SSC solenoid (7J136)
6 Clutch solenoid retainer (7G007)
7 SSA solenoid (7J136)
8 SSF solenoid (7J136)
9 SSB solenoid (7J136)
10 LPC solenoid (7G383)
11 SSD solenoid (7J136)

Solenoid Body

This transmission uses 2 types of solenoids: CIDAS and variable force solenoids.

The solenoid body contains 8 solenoids: 6 shift solenoids SSA , SSB , SSC , SSD , SSE and SSF , 1 TCC solenoid and 1 LPC solenoid. The TCC solenoid is identified by the green electrical connector. The LPC solenoid is identified by the blue electrical connector. The TFT sensor is located in the main control.

The solenoid body has a unique strategy data file that must be downloaded to the PCM . There is a 12-digit solenoid body identification and a 13-digit solenoid body strategy for each solenoid body. When a new solenoid body or transmission is installed, the scan tool must be used to get the solenoid body strategy data file and download it into the PCM .

If the PCM is replaced and the PCM data cannot be inhaled or exhaled, the solenoid body identification and solenoid body strategy must be downloaded into the PCM .

Shift Solenoids

Item Description
1 Armature/pin assembly
2 Part information

This transmission utilizes six shift solenoids (A-F) that are normally low CIDAS . Unlike previous shift solenoids they are mechanical in nature in that no transmission fluid passes through them. CIDAS s use an armature/pin assembly that moves a control valve in the main control valve body to control and apply hydraulic fluid pressure. Each clutch (A-F) has a corresponding shift solenoid (A-F) that is directly proportional in that zero current equals zero pressure and maximum current equals maximum pressure. Since there is no pressure with zero current if the power is interrupted to the shift solenoids none of the clutch packs are able to engage.

Torque Converter Clutch (TCC) Line Pressure Control (LPC)

Item Description
1 Solenoid nozzle
2 Part information

The TCC solenoid is a normally low variable force solenoid. The TCC solenoid uses proportional operation. As the current from the TCM decreases, the pressure from the solenoid decreases. As the current from the TCM increases, the pressure from the solenoid increases. The LPC solenoid is a normally high variable force solenoid. When current is high, no fluid pressure passes through the solenoid into the control circuits. When current applied to the solenoid is low, full pressure is passed through to the LPC control circuit and the main regulator valve.

Secondary Fluid Filter

Item Description
1 Secondary fluid filter
2 Cover
3 Bolts (3 required)

This transmission is equipped with a secondary fluid filter. This 30-micron filter is located at the cooler return passage in the case and filters out any debris that would have otherwise entered the transmission from the cooling system or during service when the lines are disconnected. The fluid passing through this filter goes directly into the lube circuits and then drains back down to the sump. The filter includes a bypass valve that allows fluid to continue to supply the lube circuit in the event the filter becomes blocked or restricted.

Park by Wire

  • Uses a GSM with a rotary dial or push buttons in place of a mechanical shifter as the customer interface for selecting (P, R, N, D, M).
  • The transmission hydraulic controls are modified using a park lock pawl valve connected to the park rod which unlocks and locks the parking pawl from the carrier.
    • Uses clutch C and F hydraulic pressure to push the system out of Park.
    • Once out of Park, line pressure can continue to hold the system out of Park.
  • A park lock pawl solenoid is used to allow the system to remain out of Park when the engine is not running.
  • The dual TR sensors indicate the state of the Park system and are not used to determine customer selected range, which is now provided by the GSM .

    Information on P Type Tires

    Lincoln Corsair. Information on P Type Tires

    P215/65R15 95H is an example of a tire size, load index and speed rating. The definitions of these items are listed below. (Note that the tire size, load index and speed rating for your vehicle may be different from this example.)

    P: Indicates a tire, designated by the Tire and Rim Association, that may be used for service on cars, sport utility vehicles, minivans and light trucks. Note: If your tire size does not begin with a letter this may mean it is designated by either the European Tire and Rim Technical Organization or the Japan Tire Manufacturing Association. 215: Indicates the nominal width of the tire in millimeters from sidewall edge to sidewall edge. In general, the larger the number, the wider the tire. 65: Indicates the aspect ratio which gives the tire's ratio of height to width. R: Indicates a radial type tire. 15: Indicates the wheel or rim diameter in inches. If you change your wheel size, you will have to purchase new tires to match the new wheel diameter. 95: Indicates the tire's load index. It is an index that relates to how much weight a tire can carry. You may find this information in your owner’s manual. If not, contact a local tire dealer.
