TRANSFER CASE FLUID CAPACITIES (1)
Upshift Control & Torque Converter Clutch Apply
Note. To include normal driving ranges in the following test, check shift speeds at 12, 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 (12, 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)- (Scheme 5). 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 is 30-32 MPH in 3rd gear, and 40-45 MPH in 4th gear. 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 4L60-E ELECTRONIC CONTROLS article. Check TCC operation. See «TORQUE CONVERTER DIAGNOSIS»(ref-11655-S02312028752000112200000).

TORQUE CONVERTER DIAGNOSIS
Note. Torque converter is a sealed unit and can not be disassembled. Manufacturer does not recommend testing torque converter stall speed.
Torque Converter End Play Check
- Inspect torque converter for hub scoring, cracks or weld area cracks before checking end play. Install End Play Checking Tool (J-35138) on torque converter. (Scheme 6)
- Note end play of torque converter. End play must be within specification. See «TORQUE CONVERTER END PLAY SPECIFICATIONS»(ref-11655-S25533230002000112200000) table. Replace torque converter if end play is not within specification or damage to hub area exists.
