2004 Chevrolet Corvette Parts Questions & Experts Answers

• Q: What Tools Are Required to Service and Repair the Drive Shaft of an Automatic Transmission on 2004 Chevrolet Corvette?

  A: The service and repair of an automatic transmission drive/propeller shaft demands the usage of drivetrain support fixture (J42055). A service professional should start with the task of disconnecting the negative Battery Cable and raising the vehicle. The service starts by removing rear tires with their wheels before moving on to the catalytic converters. The lh Muffler assembly should be moved aside before removing the rh Muffler assembly together with the driveline tunnel closeout panel. You need to use a flat-bladed screwdriver to remove the rear bellhousing access plug before you matchmark the transmission flexplate to the transmission Torque Converter through the access hole. You must first remove transmission flexplate to transmission Torque Converter bolts as well as the two plastic plugs that exist along the front section of the driveline support assembly. Use two lengths of m10 1.5x55 mm bolts in the plastic plug positions while securing them to 35 nm torque (26 ft. Lbs). Open the Flywheel housing access plug while you loosen the propeller shaft clamp bolt then remove the transmission Shift Cable with its bracket. Lower support the Control Arm with a straight jack before disconnecting the Tie Rod End and shock absorber mounting bolt and lower Ball Joint. Proceed with this installation sequence to the second side of the vehicle before attaching the j42055 transmission jack to the transmission while securing the assembly. To support the jack for the transmission the technician should disconnect both wiring harness and brake pipe clip retainers from the rear suspension crossmember before unscrewing the transaxle mount to Rear Crossmember nuts. The jack should be positioned underneath the crossmember. After using hand tools to eliminate the rear suspension crossmember retaining nuts you can lower and extract the crossmember. First disconnect the transaxle mount bracket to Differential bolts and separate the transaxle mount with its bracket. Secure the wheel drive shafts by releasing them from the Differential then fasten them to the underbody frame. After releasing the wiring harness retainer you can drop the driveline through angle adjustment to access electrical connectors. The vss electrical connector as well as the Differential rear cover wiring harness retainer and the transmission harness 20-way connector need to be disconnected. The first step involves disconnecting park/neutral position switch electrical connectors followed by removing the bolt that retention transmission wiring harness. The wirin harness requires clearance and then you can unfasten the transmission oil cooler rear pipes but maintain the engine support with a jack. Use an assistant to gently remove the driveline supporting bolts holding the assembly to the engine Flywheel housing before loosening the driveline with their help. After lowering the driveline carefullt from the vehicle use a lift device to shield the transmission oil cooler rear pipes. The transmission jack weight should be reduced by elevating the driveline to remove strain from the jack. Also disconnect j42055 and install the driveline on a workbench. You must disconnect both the transmission oil cooler upper and lower pipe fittings and remove transmission oil cooler pipe clips as well as transmission to driveline support assembly bolts/studs. First free the driveline support assembly from the transmission before fastening the transmission Torque Converter in place. The first step for installation consists of removing the transmission Torque Converter strap following which users should position the driveline support assembly onto the transmission while tightening its bolts/studs to 50 nm (37 ft. Lbs.). The process involves installing bolstered rear exhaust hangers while fastening their mounting bolts followed by securing the transmission oil cooler pipes with retaining clamps. Start each transmission oil cooler line fitting manually then fasten them to 40 nm torque while maintaining a 30 ft. Lbs. Torque value. Position and guide the front end of the driveline using j42055 onto the transmission jack placed under the vehicle before properly aligning it. Slowly position the driveline into the engine Flywheel housing then install the driveline support assembly to engine Flywheel housing bolts which need to be tightened to 50 nm (37 ft. Lbs.). Reinstall the wiring harness afterward you will need to lift the driveline to its intended final height. The wiring harness should be connected to both the Differential and the Vehicle Speed Sensor (VSS) and the transmission wiring harness. Install the transaxle mount and bracket by using torque settings at 50 nm (37 ft. Lbs.) and position the wheel drive shafts correctly on the Differential components. Lift the rear suspension crossmember then place new mounting nuts which should be torqued to 110 nm (81 ft. Lbs.). After removing the transmission jack, install the transaxle mount to rear suspension crossmember nuts before securely tightening them to 50 nm (37 ft. Lbs.). After supporting the lower Control Arm disconnect the wiring harness and brake pipe clip retainers to reconnect the lower Ball Joint and shock absorber. The process should be repeated for the opposite side of the automobile before placing the rear transverse spring in place and installing the wiring harness into its designated brackets. Next install the transmission Shift Cable along with its bracket while connecting it to the transmission shift lever before securing the bracket nuts to 20 nm (15 ft. Lbs.). First position the transmission flexplate toward the Torque Converter then secure the bolts while putting the rear bellhousing access plug in place. Put torque on the propeller shaft hub clamp bolt until just hand-tight and afterward remove the positioner bolts and insert the plastic plugs. Put back the driveline tunnel closeout panel and rh Muffler assembly and catalytic converters along with rear tires and wheel assemblies. After completing the programming the transmitters users can lower the vehicle while reattaching the negative Battery Cable. After reaching normal operating temperatures while idling let the engine stop before tightening the propeller shaft hub clamp bolt to 125 nm (93 ft. Lbs.). The engine Flywheel housing access plug should then be installed as well as the transmission oil cooler flushed before lowering the vehicle.
