TRANSMISSION FLUID CAPACITIES
No Engagement Of Torque Converter Clutch
Converter clutch solenoid valve defective, interruption in signal circuit, or fluid loss in converter clutch fluid circuit.
Rattling In Torque Converter Clutch
Defective torque converter clutch, or fluid pressure is inadequate.
Cannot Release Torque Converter Clutch
Converter clutch solenoid valve is defective, or return line is blocked.
Upshift Control & Torque Converter Clutch Apply
Note. To include normal driving ranges in the following test, check shift speeds at 10, 25 and 50 percent throttle angles.
- Using scan tool, monitor the following parameters: Throttle Angle Vehicle Speed Engine Speed Output Shaft Speed Commanded Gear Slip Speed Solenoid States Place gearshift lever in Overdrive. Accelerate vehicle to chosen throttle angle (10, 25 or 50 percent) and hold steady. As transmission upshifts, note vehicle speed as shift occurs for each gear change. Compare shift speeds with specification. (Scheme 1)and (Scheme 2). Check for harsh, soft or delayed shifts. Note any noise or vibration. Repeat procedure for each throttle angle.
- Check for TCC apply in 3rd and 4th gear. Note TCC apply point. Typical TCC apply speed in 4th gear is 45-55 MPH. A noticeable drop in engine RPM should be observed, and slip speed should decrease to less than 100 RPM. Ensure TCC apply speed is within specification and TCC disengages with light application of brake pedal. If TCC apply is not detected, check for DTCs. See HYDRA-MATIC 4L30-E ELECTRONIC CONTROLS article. Check TCC operation. See «TORQUE CONVERTER DIAGNOSIS»(ref-11650-S22764364882000120500000).

TORQUE CONVERTER DIAGNOSIS
Note. Torque converter is a sealed unit and can not be disassembled.
TORQUE CONVERTER
A visual inspection of torque converter may reveal converter is Blue from overheating. If torque converter has been removed from vehicle, stator roller clutch can be checked by inserting a finger into splined inner race of roller clutch and attempting to rotate race in both directions. Inner race should rotate freely clockwise, but should not rotate or should be difficult to rotate counterclockwise.
Note. See appropriate AUTOMATIC TRANSMISSION REMOVAL article in TRANSMISSION SERVICING.
