Q: How to replace the transmission pan on Chevrolet Cobalt?
A: The first step to replace the Oil Pan begins by lifting the vehicle then supporting it properly. First prepare a suitable container to catch transmission fluid before unbolting the Oil Pan along with draining the oil. First remove the Oil Pan attaching bolts followed by extracting the Oil Pan together with its gasket. Check the Oil Pan for dent damage and dry all surfaces before you install it. If the Oil Pan gasket has broken sealing ribs you must replace it with an updated gasket before installing the pan and replacing the bottom pan in case it shows damage. Put on the Oil Pan attaching bolts before securing them at 10 n.m (89 lb in) torque. Inspect the Transmission Pan after dropping the vehicle while monitoring for leakage then bring the fluid level to its correct measurement. Check the fluid level once again and look for any gasket leakage from the Oil Pan.
Q: How to service and repair the transmission pan on Chevrolet Impala?
A: The first step is to lift your vehicle while having a drain pan positioned beneath the transaxle Oil Pan. Start by removing all transaxle Oil Pan bolts from both front edges and sides followed by the careful loosening of the rear bolts. When removing the Oil Pan and case you should avoid creating damage to their mating surfaces thereby keeping oil from leaking out. A rubber mallet should lightly hit the Oil Pan to help it release while a screwdriver can be used as an alternative approach to achieve drainage. After removing transaxle bolts you can take off both the Oil Pan and its gasket. Check the Oil Pan and filter for metallic elements along with clutch facing product and rubber fragments as well as engine coolant while finding the origin of pollutants and fixing the issue. Replace the Oil Pan flange because any bending or distortion which occurred cannot be fixed. Service providers must examine Oil Pan bolt washers when removing the bottom oil to change any inverted components and their respective bolts. Dry oil film must be eliminated from the Oil Pan and case flanges before cleaning the case while it air dries. The service includes cleaning and air drying Oil Pan Gasket surfaces until you remove all remnants from the previous gasket material. Place the Oil Pan Gasket before repositioning the Oil Pan between these components. Secure the Oil Pan bolts by tightening them to 14 nm (10 ft. Lbs.). Begin by lowering the vehicle and add dexron iii fluid into the transaxle while keeping the gear selector in park position. After starting the engine at a slow idle speed without racing the vehicle proceed to adjust fluid level and perform leak inspection.
Q: How to replace the transmission pan on a 4T45-E automatic transaxle on Chevrolet Malibu?
A: When replacing an Oil Pan for a 4t45-e automatic transaxle you should first position the vehicle properly along with supporting it adequately. After hoisting the vehicle position a drain pan below the transaxle Oil Pan. First remove front Oil Pan bolts together with the ones located on the sides and then turn the rear bolts four turns for easier removal. Completely remove the Oil Pan by using small pry tools, while preventing damages to the transaxle case and sealing points. You can assist the process by using a rubber mallet or by carefully prying the pan gently to let the oil drain. Few more bolts remain before the Oil Pan removal and Oil Pan Gasket removal process while properly cleaning off all remaining old gasket material. Use solvent to clean both transaxle case and Oil Pan Gasket surfaces before letting them dry naturally. Start the Oil Pan bolts manually then tighten them to 12 n.m (9 lb ft). The transaxle requires a refill of dexron(R) iii p/n 21019223 transaxle fluid or its equivalent to reach the specified fluid amounts of 6.5 l (6.9 qt) for bottom pan removal and 9 l (9.5 qt) for complete overhaul or 12.2 l (12.9 qt) for dry capacity at this stage. Begin the engine operation followed by warming the transaxle system then inspect all fluids for leaks while monitoring the fluid level.
