Park - Engine Running

When the gear selector lever is in the Park (P) position and the engine is running, fluid is drawn into the oil pump and line pressure is directed to the pressure regulator valve.

Scheme 97

Reverse

When the gear selector lever is moved to the Reverse (R) position - from the Park position, the following changes occur in the transmission's hydraulic and electrical systems

Reverse Clutch Applies

Scheme 98

Neutral - Engine Running

When the gear selector lever is moved to the Neutral (N) position, the hydraulic and electrical system operation is identical to Park (P) range. However, if Neutral is selected after the vehicle was operating in Reverse (R), the following changes would occur in the hydraulic system

Low and Reverse Clutch Releases

Scheme 99

Overdrive Range, First Gear (Before First 1-2 Shift)

When the gear selector lever is moved to the Overdrive range position (D), from the Neutral (N) position, before the first 1-2 shift has occurred, the following changes occur to shift the transmission into Overdrive Range - First Gear.

Scheme 100

Overdrive Range, First Gear (After First 1-2 Shift)

When the gear selector lever is moved to the Overdrive range position (D), from the Neutral (N) position, after the first 1-2 shift has occurred, the following changes occur to shift the transmission into Overdrive Range - First Gear.

Scheme 101

Overdrive Range, Second Gear

As vehicle speed increases, the transmission control module (TCM) receives input signals from both the input and output speed sensors, the throttle position (TP) sensor and other vehicle sensors to determine the precise moment to energize or "turn ON" the 1-2 shift solenoid (SS) valve.

Scheme 102

Overdrive Range, Third Gear

As vehicle speed increases, the TCM receives input signals from both speed sensors, the TP sensor and other vehicle sensors to determine the precise moment to de-energize or "turn OFF" the 2-3 shift solenoid (SS) valve. The 2-3 solenoid is OFF when the TCM removes the path to ground for that electrical circuit. This allows 2-3 signal fluid to exhaust at the 2-3 SS valve.

Scheme 103

Overdrive Range, Fourth Gear

As vehicle speed increases, the TCM receives input signals from both speed sensors, the TP sensor and other vehicle sensors to determine the precise moment to de-energize or "turn OFF'" the 1-2 shift solenoid (SS) valve, and to energize or "turn ON" the 4-5 SS valve.

Scheme 104

Overdrive Range, Fifth Gear - Torque Converter Clutch (TCC) Released

Overdrive Range - Fifth Gear is used to maximize engine efficiency and fuel economy under most normal driving conditions. In order to shift the transmission into Fifth gear, the TCM receives input signals from both speed sensors, the TP sensor and other vehicle sensors to determine the precise moment to de-energize or "turn OFF" the 4-5 shift solenoid (SS) valve.

Scheme 105

Overdrive Range, Fifth Gear - Torque Converter Clutch (TCC) Applied

When the TCC pressure plate is applied, it is held against the torque converter cover. Since it is splined to the converter turbine hub, it provides a mechanical coupling - direct drive of the engine to the transmission gear sets. This mechanical coupling eliminates the small amount of slippage that occurs in the fluid coupling of a torque converter, resulting in a more efficient transfer of engine torque through the transmission and to the drive wheels.

Scheme 106

Manual Fourth Gear

Manual Fourth - Fourth Gear - Drive Range may be selected at any time while the vehicle is being operated in a forward gear range. However, TCM control prevents the transmission from shifting into Fifth gear. When the gear selector lever is moved to Drive Range (4) from Overdrive Range (D), the manual valve also moves. Changes to the hydraulic and electrical systems are as follows

Coast Clutch Applies

In Manual Fourth - Fourth Gear, the TCC will not release if Manual Fourth was selected while the vehicle was operating in Overdrive Range - Fifth Gear with the TCC applied. Under normal operating conditions, the converter clutch operates the same way in Manual Fourth - Fourth Gear as in Overdrive Range - Fourth Gear.

Scheme 107

Manual Third Gear

Manual Third - Third Gear may be selected at any time while the vehicle is being operated in a forward gear range. However, TCM control prevents the transmission from shifting above Third gear. When the gear selector lever is moved to Manual Third range from Manual Fourth - Fourth Gear, the manual valve also moves. Changes to the hydraulic and electrical systems are as follows

Shift Accumulation

In Manual Third - Third Gear, the TCC will not release if Manual Third was selected while the vehicle was operating in Overdrive Range - Fifth Gear with the TCC applied. Under normal operating conditions, the converter clutch operates the same way in Manual Third - Third Gear as in Overdrive Range - Third Gear.

Scheme 108

Manual Second Gear

Manual Second - Second Gear may be selected at any time while the vehicle is being operated in a forward gear range. However, TCM control prevents the transmission from upshifting above Second gear. When the gear selector lever is moved to Manual Second from Manual Third - Third Gear, the manual valve also moves. Changes to the hydraulic and electrical systems are as follows

Second Coast Clutch Applied

If the converter clutch was applied when Manual Second was selected it will release during downshifting. Under normal operating conditions the converter clutch will not re-apply in Second gear.

Scheme 109

Manual Second - First Gear
