Transmission Pan

As a first step in Oil Pan replacement you must elevate the automobile. The quantity of transmission fluid needs to be calculated during this step because usable fluid can be transferred into a sanitary receptacle for further use. First remove both the Drain Plug along with Drain Plug seal from the Oil Pan until fluid drains into an appropriate storage container. Inspect the drained fluid. Traverse the 12 bolts to hold the Oil Pan in position before removing the last bolt then extract the Oil Pan together with its gasket. Check the magnet for significant or large metallic dust particles because these signs would require transmission rebuild or new transmission. You should keep the transmission internal oil filter seal in place for pan or gasket replacement alone. Pull the transmission internal oil filter from the suction tube in transmission case downward then discard old components from the filter or seal bore. The installation process starts with cleaning all gasket material from the transmission case followed by a confirmation of complete scratch elimination to prevent leakage. Install a new sealing component to the transmission internal oil filter tube after removal by placing the seal against the shoulder at the internal oil filter tube end. Position the filter with its attached seal properly inside the transmission case seal bore by pushing them through the bore. Mount the transmission case Oil Pan using two m8 x 1.25 headless guide bolts installed in opposite corners before placing the gasket. Place the gasket and Oil Pan over the guide bolts allowing you to secure the bolts by adding their screws respectively. Fasten the 10 new Oil Pan bolts with 27 nm torque (20 ft. Lbs.) until they are secure. Insert the Drain Plug together with its Drain Plug seal before tightening the plug to 35 nm (26 ft. Lbs.). When recharging the transmission with dexron(r)vi automatic transmission fluid users must remember that drained fluid stays inside external circuits and transmission cavities. The last step requires checking the transmission fluid level.

The first step to change an Oil Pan requires increasing the vehicle height. Remove the Drain Plug and its Drain Plug seal from the Oil Pan so fluid can drain into a suitable contained while you record fluid amount loss since reusable fluid remains in good condition. The drainage process should begin with fluid inspection before removing 12 bolts where the Oil Pan remains fixed once the last bolt becomes loose. Remove the Oil Pan along with its gasket so you can check the magnet for big metallic pieces that would signal transmission failure. You should pull down the transmission internal oil filter to remove it from the suction tube in the transmission case but keep both filter and seal intact when handling only the Oil Pan or gasket replacement operation. After removing the transmission internal oil filter seal from its position either in the filter bore or the transmission case you must discard both elements when replacing anything. Remove all gasket residue from the transmission case while also fixing any damage which might result in leakage. Fitting a new seal onto the transmission internal oil filter tube's tube requires placing it against its shoulder before pushing filter and new seal into the transmission case's seal bore. Position 2 m8 x 1.25 headless guide bolts into the transmission case Oil Pan mounting face corners before placing a gasket over the pan and correctly setting the bolt holes. Set the gasket and Oil Pan over the guide bolts before keeping them steady to fasten 2 bolts . Guide bolts removal should be followed by tightening ten remaining Oil Pan bolts to 27 nm (20 ft. Lbs.). Insert the Drain Plug followed by its Drain Plug seal before tightening it to 35 nm (26 ft. Lbs.). Lower the vehicle while filling it with dexron(r)vi automatic transmission fluid which requires clean and approved fluid type only before inspecting the transmission fluid level since drained fluid remains in exterior circuits and transmission cavities.

You need to raise the vehicle before the allison automatic transmission Oil Pan replacement begins under the following protocol. First measure the amount of transmission fluid lost from the original pan because viable fluid from good condition can be reused. The Oil Pan drain operation requires users to extract the Drain Plug and Drain Plug seal from the Oil Pan so the fluid flows into a suitable container while they examine the drained fluid. Remove the 12 bolts from the Oil Pan while supporting the pan to complete bolt removal before you can remove the entire pan with its gasket. An excessive volume or size of metal particles on the magnet during inspection would require either transmission replacement or repair. The replacement of an Oil Pan and gasket should only be conducted without touching the transmission internal oil filter or seal. To replace the filter pull the transmission internal oil filter downward from the suction tube in the transmission case before discarding it together with the old seal. Remove all transmission gasket material from the case while eliminating any scratching on the surface that might lead to leakage. Position the new seal onto the tube of the transmission internal oil filter then slide the filter and seal into the transmission case seal bore with correct alignment. Affix 2 m8 x 1.25 headless guide bolts in opposing corners of the Oil Pan mounting surface, before you implement the gasket which will also receive the Oil Pan. Secure the gasket and Oil Pan over the guide bolts using two bolts before you remove the guide bolts and install ten Oil Pan bolts that should be tightened to 27 n.m (20 lb ft). Place the Drain Plug with its seal while tightening it to 35 n.m (26 lb ft), then bring the vehicle to the ground. Add dexron(R)vi automatic transmission fluid while considering the fluid that stayed in the external circuits and transmission cavities before checking the transmission fluid level.

Remove 12 bolts while holding the oil pan in position as the last bolt is removed, then take off the oil pan and gasket.
