The first step to replace an automatic transmission flex plate requires removal of the automatic transmission while documenting the direction and position of the engine Flywheel before taking it out. First unfasten the bolts securing the Flywheel and after that unmount the Flywheel. Two m11x1.5 mm bolts must be installed into the threaded holes on the spacer before rotating them clockwise to separate it from the Crankshaft's rear end. First position the spacer onto the Crankshaft rear then use longer Flywheel bolts when the installation requires a Flywheel spacer. Place the Flywheel on the Crankshaft before inserting bolts and adding threadlock to the Flywheel bolt threads according to the specified part number of sealers and lubricants. Jane should execute Flywheel bolt installation by following this method - starting with 20 n.m (15 lb ft), then moving to 50 n.m (37 lb ft) and culminating in 100 n.m (74 lb ft). The automatic transmission installation should follow these completion steps.

When replacing an automatic transmission flex plate begin by removing the transmission as well as marking down the position and direction of the engine Flywheel before extraction. Begin by removing the two Flywheel bolts before taking out the Flywheel. Position the Flywheel along with bolts onto the Crankshaft according to the threads of the Flywheel bolts but with threadlock applied using the correct adhesive part number. One needs to exercise care while working with fasteners because improper handling can result in vehicle damage. The installation requires several passes of bolting the Flywheel where the first pass reaches 20 nm (15 lb ft), then a second pass reaches 50 nm (37 lb ft) and the final pass concludes at 100 nm (74 lb ft). Finally, install the automatic transmission.

The first step for engine Flywheel replacement involves setting aside the automatic transmission then marking down the Flywheel position before extractor tools remove it. Start by removing all bolts securing the Flywheel followed by0241 removal of the Flywheel component. To eliminate the spacer from the Crankshaft rear utilize two m11x1.5 mm bolts threaded into spacer holes while rotating them clockwise. After applying the spacer to the Crankshaft rear position install the Flywheel followed by the bolts so their length must be extended for spacer application existence. Subsequently apply threadlock gm p/n 12345382 (Canadian P/N 10953489) or its equivalent version to the Flywheel bolt threads. Follow the sequence of Flywheel bolt torquing beginning with 20 nm (15 ft. Lbs.), then 50 nm (37 ft. Lbs.) and finishing with 100 nm (74 ft. Lbs.). The automatic transmission requires reinstallation after performing these requirements.

The first step to replace the engine Flywheel involves removing the automatic transmission while recording the Flywheel position and its direction before extraction. Break the first step by turning out the bolts securing the engine Flywheel before removing it. A detailed check for dirt and damages should be performed on the engine Flywheel. During the Flywheel Crankshaft mounting process keep in mind that it lacks a locating pin to ensure proper alignment because it will slide onto the Crankshaft by the engine Flywheel bolt force before achieving Crankshaft flange or spacer mating. Longer engine Flywheel bolts should be utilized while working with Flywheel spacers. Properties of threadlock gm p/n 12345382 (Canadian P/N 10953489) or alternative should be applied to Flywheel bolt threads. You must install engine Flywheel bolts following this procedure: start by tightening the bolts to 20 nm (15 ft. Lbs.), then move to 50 nm (37 ft. Lbs.), and finish by tightening to 100 nm (74 ft. Lbs.). Put the automatic transmission back into its original position right after establishing the Flywheel.

Begin replacing the engine Flywheel by removing the automatic transmission while paying attention to the orientation of the engine Flywheel during extraction. The next step involves removing all engine Flywheel bolts before taking away the automatic transmission engine Flywheel. Two m11x1.5 mm bolts can be inserted into the spacer threaded holes at the Crankshaft rear before they are detached by rotating them clockwise. Position the spacer on the Crankshaft rear before installing the automatic transmission engine Flywheel to the Crankshaft. Longer Flywheel bolts should always be used when installing a spacer between the automatic transmission engine Flywheel and Crankshaft. Knowledge-based formula gm p/n 12345382, canada p/n 10953489 matches another available product which should be applied onto Flywheel bolt threads. The engine Flywheel bolt installation should follow a sequential process of torquing each bolt to 20 nm (15 ft. Lbs.) followed by 50 nm (37 ft. Lbs.) and ending at 100 nm (74 ft. Lbs.). You must reinstall the automatic transmission after finishing the installation process.

The repair process starts with removing the automatic transmission if present followed by the disconnecting of the negative Battery Cable. Service the Flywheel according to the transmission replacement or transmission replacement in automatic transmission - 4l80-e guidelines. The first step requires automatic transmission Flywheel removal followed by manual transmission removal according to transmission replacement in manual transmission-nv 3500 or transmission replacement in manual transmission-nv 4500 procedures until the manual transmission Flywheel is free for removal. The technician should carry out a thorough examination and cleaning operation of the Flywheel. First install the manual transmission Flywheel as your base while installing the manual transmission according to either transmission replacement in manual transmission-nv 3500 or transmission replacement in manual transmission-nv 4500 standard procedures. The automatic transmission Flywheel and transmission should be installed afterwards according to the replacement instructions named transmission replacement in automatic transmission-4l60-e or transmission replacement in automatic transmission-4l80-e. Close the procedure by reconnecting the negative Battery Cable.

The starting point for replacing an engine Flywheel begins with removing the transmission then marking both the Flywheel position and its direction before removal. Then remove the Flywheel bolts and afterward the Flywheel itself. Thorough inspection together with cleaning of the Flywheel is necessary. The installation of the new Flywheel requires threadlock on its bolts together with the correct part number selection for all required adhesives, fluids and lubricants along with sealers. Factored fastener installation requires attention as it prevents damage to vehicles during maintenance. The new Flywheel needs installation while using new bolts which should be tightened in the proper sequence to reach 25 nm (18 lb ft). Apply the j 36660-a torque angle meter to add 50-degree additional torques to the bolts. Finally, reinstall the transmission.

The first step to replace the automatic transmission flex plate includes removing the automatic transmission by documenting the engine Flywheel position then its direction before withdrawal. The second step involves separating the Flywheel bolts before taking away the Flywheel. Start by mounting the Flywheel with its bolts onto the Crankshaft and apply threadlock to the threads of the Flywheel bolts according to the correct part number specifications for all required adhesives and fluids and lubricants and sealers. Proceed with caution when working with fasteners since it could lead to vehicle damage. Use a torque wrench to install the Flywheel bolts starting from 20 nm (15 lb ft) then 50 nm (37 lb ft) and finishing at 100 nm (74 lb ft) in all cases. Finally, reinstall the automatic transmission.

Begin the automatic transmission flex plate replacement by removing the transmission while recording the engine Flywheel position and direction before extracting it. Begin by removing both the Flywheel bolts before taking out the Flywheel itself. Two m11x1.5 mm bolts should be installed into threaded holes of the spacer before you rotate them clockwise to extract the spacer from the Crankshaft end. To install the spacer you should fit it on the Crankshaft rear section while utilizing extended Flywheel bolts if the spacer exists. Install the Crankshaft-mounted Flywheel along with its bolts while applying threadlocking substance according to the correct part specifications. The technician should carry out three separate pass sequences to tighten Flywheel bolts: starting with 20 n.m (15 lb ft), then moving to 50 n.m (37 lb ft), and finally reaching 100 n.m (74 lb ft). Finally, reinstall the automatic transmission.
