How to service and repair the flex plate and replace the engine flywheel on 2008 Chevrolet Trailblazer?

Service and repair of the flex plate requires displacing the transmission from its position first. Take note of the position as well as direction of the engine Flywheel before you start removing it. You should first remove the Flywheel bolts before taking out the Flywheel itself. Perform a detailed inspection on the Flywheel while it remains under proper cleaning conditions. The installation of the new Flywheel requires threadlock application to new Flywheel bolts while using appropriate part numbers for all sealers and adhesive and lubricant materials. Fasten the Flywheel in place by using new bolts that need to be tightened sequentially to 25 n.m (18 lb ft). After securing the transmission bolts with 50 degrees of additional turn using the torque angle meter (J 36660-A) reinstall the transmission.
