Drive Plate

Before beginning the automatic transmission flex plate replacement you must remove the automatic transmission if present while making a record of engine Flywheel direction until the automatic transmission is removed properly. Proceed by removing both the engine Flywheel bolts and subsequent automatic transmission engine Flywheel. Clean the engine Flywheel while also installing 2 m11x1.5 mm bolts into the threaded spacer holes on the Crankshaft rear for spacer removal by turning the bolts clockwise. To install the components begin with positioning the spacer onto the Crankshaft rear if needed followed by automatic transmission engine Flywheel deployment. Extend the length of Flywheel bolts when working with spacers while applying threadlocker to these bolts and installing them. The engine Flywheel bolts must be secured in a specific installation sequence using torque specifications that start at 20 n.m (15 lb ft), then rise to 50 n.m (37 lb ft) and end at 100 n.m (74 lb ft). Afterward, install the automatic transmission.

The first step to change the engine Flywheel involves removing the automatic transmission by keeping track of its orientation while also remembering the initial position of the engine Flywheel before extraction. The procedure begins with unfastening the engine Flywheel bolts followed by automatic transmission engine Flywheel removal. The first step involves cleaning and inspecting the engine Flywheel while you also prepare to install two m11x1.5 mm bolts in the threaded holes of the spacer which enables removal of the spacer from the Crankshaft rear end by rotating them clockwise. The automatic transmission engine Flywheel gets installed after setting the front spacer (if necessary) on the Crankshaft rear. Applications that need a Flywheel spacer must use extended Flywheel bolts and thread-lock should be applied to the bolt threads. The engine Flywheel bolts need installation in series while torquing begins at 20 n.m (15 lb ft) for the first round followed by 50 n.m (37 lb ft) for the second round and finishing at 100 n.m (74 lb ft) during the final round. Finally, reinstall the automatic transmission.

If applicable, install 2 M11x1.5 mm bolts into the threaded holes of the spacer and rotate them clockwise to remove the spacer.

Apply threadlock GM P/N 12345382 (Canadian P/N 10953489) or equivalent to the threads of the flywheel bolts.

Use longer flywheel bolts for applications with a flywheel spacer.
