Upshift Control and Torque Converter Clutch (TCC) Apply
The PCM calculates the upshift points based primarily on two inputs: throttle angle and vehicle speed. When the PCM determines that conditions are met for a shift to occur, the PCM commands the shift by closing or opening the ground circuit for the appropriate solenoid.
Perform the following steps
- Refer to the «Shift Speed»(ref-174512-S33850593312005050500000) table in this section and choose a throttle position of 12 percent, 25 percent or 50 percent. All throttle angles shown should be tested to cover the normal driving range.
- Monitor the following scan tool parameters: Throttle angle Vehicle speed Engine speed Output shaft speed Commanded gear Slip speed Solenoid states
- Place the gear selector in the OVERDRIVE position.
- Accelerate the vehicle using the chosen throttle angle. Hold the throttle steady.
- As the transmission upshifts, note the vehicle speed when the shift occurs for each gear change. There should be a noticeable shift feel or engine speed change within 1 to 2 seconds of the commanded gear change.
- Compare the shift speeds to the Shift Speed table. Refer to «Shift Speed»(ref-174512-S33850593312005050500000) . Shift speeds may vary slightly due to transmission fluid temperature or hydraulic delays in responding to electronic controls. Note any harsh, soft or delayed shifts or slipping. Note any noise or vibration.
- Repeat steps 1 through 6 to complete all throttle angles. Important: This transmission is equipped with an electronically controlled capacity clutch (ECCC). The pressure plate does not fully lock to the torque converter cover. Instead, the pressure plate maintains a small amount of slippage, about 20 RPM, in SECOND, THIRD and FOURTH gears, depending on the vehicle application. ECCC was developed to reduce the possibility of noise, vibration or chuggle caused by TCC apply. Typical apply speeds are 49-52 km/h (30-32 mph) in THIRD gear and 65-73 km/h (40-45 mph) in FOURTH gear. Full lockup is available at highway speeds on some applications. Important: The TCC will not engage until the engine is in closed loop operation and the vehicle speed is as shown in the Shift Speed table. Refer to «Shift Speed»(ref-174512-S33850593312005050500000) . The vehicle must be in a near-cruise condition, not accelerating or coasting, and on a level road surface.
- Check for TCC apply in THIRD and FOURTH gear. Note the TCC apply point. When the TCC - applies there should be a noticeable drop in engine speed and a drop in slip speed to below 100 RPM. If the TCC apply can not be detected: Check for DTCs. Refer to «Torque Converter Diagnosis Procedure»(ref-174512-S06326321952005040600000) . Refer to the «Shift Speed»(ref-174512-S33850593312005050500000) table for the correct apply speeds. Lightly tap and release the brake pedal. The TCC will release on most applications.
Torque Converter Diagnosis Procedure
The Torque Converter Clutch (TCC) is applied by fluid pressure, which is controlled by a PWM solenoid valve. This solenoid valve is located inside of the automatic transmission assembly. The solenoid valve is controlled through a combination of computer controlled switches and sensors.
Torque Converter Stator
The torque converter stator roller clutch can have two different malfunctions.
- The stator assembly freewheels in both directions.
- The stator assembly remains locked up at all times.
Torque Converter Clutch Shudder
The key to diagnosing Torque Converter Clutch (TCC) shudder is to note when it happens and under what conditions.
TCC shudder which is caused by the transmission should only occur during the apply or the release of the converter clutch. Shudder should never occur after the TCC plate is fully applied.
Indexing Torque Converter
To determine and correct a torque converter vibration, the following procedure may have to be performed several times to achieve the best possible torque converter to flywheel balance.
Scheme 296
- Raise and suitably support the vehicle.
- Rotate the torque converter one bolt position.
- Align the torque converter hub (2) in the engine crankshaft (3) and install the torque converter to flywheel bolts.
- Lower the vehicle.
- With the engine at idle speed and the transmission in PARK or NEUTRAL, observe the vibration. Refer to «Noise and Vibration Analysis»(ref-174512-S30931086142005040600000) . Repeat this procedure until you obtain the best possible balance.
- Install the transmission converter cover bolts and the cover.
Leak at the Torque Converter End
- Converter leak in the weld area
- Converter seal lip cut. Check the converter hub for damage
- Converter seal bushing moved forward and damaged
- Converter seal garter spring missing from the seal
- Porous casting of the transmission case or the oil pump
Scheme 297
- Overfilled system
- Water or coolant in the fluid. The fluid will appear milky
- Transmission case porous
- Incorrect fluid level indicator
- Plugged vent
- Drain-back holes plugged
- Mispositioned oil pump to case gasket, if equipped
