You can Select Your Vehicle to check if 24210956 fits your vehicle.

Purchase the specified transmission fluid and a new filter. Gather other necessary tools such as a floor jack, jack stands, a drain pan, newspapers, and clean rags.

At the specified intervals, the transmission fluid should be drained and replaced. The fluid will remain hot long after driving, so perform this procedure only after the engine has cooled down completely. Before beginning work, purchase the specified transmission fluid and a new filter. Other tools necessary for this job include a floor jack, jack stands to support the vehicle in a raised position, a drain pan capable of holding at least eight pints, newspapers and clean rags. Raise the vehicle and support it securely on jackstands. Remove the center transmission mount nut. Use a floor jack positioned under the transmission pan to raise the transmission slightly. Place a block of wood between the pan and jack head to prevent damage to the pan. Once the transmission Is raised, insert a small wood block between the mount and crossmember. Place the drain pan underneath the transmission pan. Remove the front and side pan mounting bolts, but only loosen the rear pan bolts approximately four turns. Carefully pry the transmission pan loose with a screwdriver, allowing the fluid to drain. Remove the remaining bolts, pan and gasket. Carefully clean the gasket surface of the transmission to remove all traces of the old gasket and sealant. Drain the fluid from the transmission pan, clean it with solvent and dry it with compressed air. Remove the filter from the mount inside the transmission. If the seal did not come out with the filter, remove it from the transmission. Install a new filter and seal. Make sure the gasket surface on the transmission pan is clean, then install a new gasket on the pan. Put the pan in place against the transmission and, working around the pan, tighten each bolt a little at a time until the final torque figure is reached. Lower the vehicle and add approximately seven pints of the specified type of automatic transmission fluid through the filler tube. With the transmission in Park and the parking brake set, run the engine at a fast idle, but don't race it. Move the gear selector through each range and back to Park. Check the fluid level. It will probably be low. Add enough fluid to bring the level up to the COLD FULL range on the dipstick. Check under the vehicle for leaks during the first few trips.

If there's a drain plug, remove it, allow the fluid to drain until it barely trickles, and then reinsert the plug.

Always at the designated maintenance intervals, there should be a changing of transmission fluid. However, do not commence until the engine is completely cooled. Begin by getting a fresh pan gasket, new filter and transmission fluid. The tools to have include drain pan with sufficient capacity, clean rags, newspapers, jackstands for secure vehicle support, floor jack and others. Elevate the vehicle and secure it on jackstands if pan removal is obstructed by exhaust system front section. Underneath the transmission pan have a drain pan in position, remove drain plug (if available), allow fluid to drain till trickling stops and then replace the plug again. Remove bolts from three sides of the pan if there's no drain plug; loosen the remaining ones slightly and lower the pan to get rid of most of the fluid in it. Then remove bolts carefully lower the pan and let out all the remaining fluid in it. Remove heat shield close to catalytic converter on right hand side to access pan bolts. On driver's side, for accessing pan bolts remove shift linkage. Undoing transmission pan mounting bolts with screwdriver gently pry off the pan. Clean up gasket surface thoroughly on transmission to get rid of any leftover old gasket or sealant materials thereon.Turn off your vehicle and disconnect 12V battery negative terminal.New one must be fitted while referring to diagrams & instructions given by manufacturer as this cannot be done any other way.Make sure that new gasket is attached to clean transmission pan's gasket surface before placing back onto transmission & tightening all bolts.Refer to powertrain control/emissions diagnosis manual for proper diagnostic steps.Remove heat shield close to catalytic converter on right hand side to access pan bolts.Do not drive anymore; rather shift lever will stay put at any chosen gear.The power from engine has been evenly distributed through five gears but only one is used at any given moment.Clean up gasket surface thoroughly on transmission to get rid of any leftover old gasket or sealant materials thereon. This must be done with the engine running at fast idle speed, transmission in Park and cycling through each gear position back to Park before returning to idle.Thus the fluid level will be low and it will have to be added until it reaches the mark on the dipstick but without overfilling.Turn off your vehicle and disconnect 12V battery negative terminal.New one must be fitted while referring to diagrams & instructions given by manufacturer as this cannot be done any other way.Make sure that new gasket is attached to clean transmission pan's gasket surface before placing back onto transmission & tightening all bolts.Refer to powertrain control/emissions diagnosis manual for proper diagnostic steps.With the engine running at a fast idle and the transmission in Park, cycle the gear selector through each range and back to Park before letting the engine idle.Tighten each bolt gradually to the specified torque. Reinstall components removed for pan bolt access, lower the vehicle, and add about 4 quarts of the specified automatic transmission fluid through the filler tube.The above mentioned procedure should be performed every 30,000 miles.As such, the fluid level is likely to be low hence more should be included until it hits line on dipstick avoiding overfilling.Finally look out for leaks beneath vehicle during first trips and when transmission is hot check again its fluid level.

If there's no drain plug, remove the bolts from three sides of the pan, partially loosen the remaining bolts, and lower the pan to drain most of the fluid. Afterward, remove all the bolts, carefully lower the pan, and drain the remaining fluid.

No, the oil pan gasket will need to be purchased separately

Yes, a new grommet is included with the filter
