There is a cross-over or "y" pipe that is under the rear edge of the pan. The nuts that bolt this exhaust pipe to the front pipes are usually very very rusty when I see them. I usually wind up using an oxy-acetalene torch to heat the nuts red hot and then a pair of pliers or vise grips to turn the nuts off of the studs. You will want to replace these nuts when you go back together. I would also recommend putting anti-seize on the studs prior to installation of the nuts to make it easier to take apart next time should you need to. The thread of the studs is 10MM X 1.25.

Hope this is helpful.

How to replace oil pan


5.2 liter V8 engine?

Remove the four front skid-plate bolts holding the front skid plate, using a ratchet and socket. Remove the skid plate.

Pull the plastic splash shield away from the vehicle, loosening the retaining clips. Remove the splash shield.


  • Place an oil drain container under the oil pan. Loosen the drain fitting with a wrench until oil drains from the pan. When oil is done draining, tighten the drain fitting.

  • Disconnect the electrical connections running to the starter motor. Remove the starter motor mounting bolts with a ratchet and socket, then remove the starter motor.
  • Remove the oxygen sensor socket from the exhaust pipe, using a wrench.
  • Remove the exhaust manifold bolts where the exhaust meets the manifold on both sides, using a ratchet and socket
  • Place an jack under the transmission to support it. Remove the pressure on the transmission crossmember.

  • Remove the bolts that hold the transmission crossmember in place, using a ratchet and socket. Then remove the crossmember. Place a jack stand under the transmission to keep the transmission from falling off the jack if hit. Once removed, the exhaust will hang down, allowing enough room to remove the oil pan.
  • Disconnect the oil level sensor and the nut retaining the transmission cooling lines, using a wrench.
  • Remove the oil pan bolts with a ratchet and socket, then remove the oil pan and gasket.
  • Clean the mounting surfaces of the new oil pan and engine block. Make sure what ever you use to clean the surfaces dosn't gouge the metal.
  • Place a coat of RTV (gasket) sealer on the engine block where the pan will meet the rear main cap.
  • Place the new gasket on the pan and push the new oil pan into place. Finger tighten the oil pan mounting bolts to hold it in place. Tighten the bolts with a torque wrench to 18 ft-lbs. DO NOT OVER TIGHTEN THE BOLTS! Doing so will cause the gasket to deform and create leaks!

  • Connect the oil level sensor and the nut retaining the transmission cooling lines, using a wrench.
  • Place the exhaust back into position and replace the transmission crossmember bolts and crossmember with a ratchet and socket.
  • Remove the jack supporting the transmission.
  • Connect the exhaust back to both sides of the manifold, tightening the bolts with a torque wrench to 20 ft-lbs.
  • Attach the oxygen sensor socket to the exhaust pipe with a wrench.

  • Replace the starter motor by installing the starter motor mounting bolts with a ratchet and socket. Connect the electrical connections to the starter motor that were disconnected during removal.
  • Push the retaining clips on the plastic splash shield into the appropriate retaining clip holes.
  • Replace the front skid plate by replacing the four front skid plate bolts with a ratchet and socket.
  • Fill the engine with 5 quarts of oil. Make sure to check the level on the dipstick to find the exact level when filling.

    Gear selection is slow


    Check your tranmission fluid level, if its low it can cause your transmission to shift slower, if its drastically low your transmission will slip in and out of gears or free rev (act like its in neutral) under acceleration or when shifting to a higher gear. If your fluid level is good, then you need to change your transmission filter. If your not mechanically inclined, take your vehicle to a shop and have them replace your filter for you, any repairs or maitnance envolving your transmission can easily go bad and potentially destroy your transmission if you do something wrong.

    1. Buy new filter & transmission pan gasket

    2. Raise vehicle, block tires, and use jackstands (never rely on any type of jack to hold the vehicle up.) and get a container or drain pan to catch the old transmission fluid.

    3. Put drain pan or container under your transmission pan, start loosinging the bolts that hold the pan to the transmission. If you loosen the bolts alittle at a time you should be able to minimize spilling fluid everwhere and be able to catch it in your drain pan easier. (if your transmission has a drain plug remove it before loosening the pan bolts, this is not very common though and if you have a drain plug your lucky) once the majority of the fluid has drained from loosening the plugs, continue to loosen bolts so you drop the pan easily cause its gonna be full of fluid (unless you have the drain plug, if you do the pan should be virtually empty and you can remove it fully without alot of mess).

    4. Locate the bolts that hold your filter to the transmission, be sure to only remove the bolts that hold the filter. Use the new filter for a visual aid so you can be 100% sure your only removing the filter. (The filter is bolted to a metal cover plate that houses the transmission clutch assemblies, spring valve assemblies, and floating shutter pins and they all operate under hydraulic pressure). Once the bolts are out of the old filter you should be able to slide the goose neck of the filter out of the filter port (again use the new filter for a visual aid) The goose neck should have a rubber o-ring type seal (or equivilent) make sure its on the old filter when you pull it, If its not then gently feel in the port and make sure the seal isnt sticking inside the port.


    ****** If you were to remove the cover plate thinking it was the filter, the hydraulic slide valves would move and you could seriously damage your transmission turning a $30.00 problem into a 1500.00 problem. I speak from experiance, so please use the new filter for a visual, I can't stress it enough*

    5. Clean the pan's gasket area maticuliously, removing all of the old gasket, do the same to the transmission. Prep the pan side of your new gasket (I like using permatex gasket sealer) and install it to your transmission pad. (you can do this before you clean the transmission's gasket area so the permatex has time to adhear to the pan while you clean the gasket area on the transmission)

    6. Using transmission fluid lube up the new filter's o-ring and slide it into the filter port. line up the bolt holes and start puting the filter bolts back in, tightening them evenly much like you would do to lug nuts if you had to change a tire.

    7. Now get your pan and prep the other side of the pan gasket (gasket should be well tacky and sticking to the pan at this point) once the gasket is prep'd line the pan up with the transmission and begin installing the pan bolts tighten them the same way you did the filter bolts,

    **Note**FWD** Depending on your vehicle's make/model, you may have to drop one of the control arms to remove the pan.

    **Note**RWD** Depending on your vehicle's make/model, you may have to remove the cross member to remove the pan -or- drop the drive shaft, remove the bell housing bolts (bolts through transmission into engine block) remove the starter, and flywheel cover remove the bolts that connect your torq converter to your flywheel and slide the transmission back from the motor far enough so the transmission pan is no longer under the cross member.

    GOOD LUCK I HOPE MY POST HELPS YOU!

    Need to change the transmission filter how and where is it located


    Fluid & Filter Change Under normal service (moderate highway driving excluding excessive hot or cold conditions), the manufacturer feels that automatic transmission fluid should not need periodic changing. However, if a major service is performed to the transmission, if transmission fluid becomes burnt or discolored through severe usage or if the vehicle is subjected to constant stop-and-go driving in hot weather, trailer towing, long periods of highway use at high speeds, fluid should be changed to prevent transmission damage. A preventive maintenance change is therefore recommended for most vehicles at least every 90,000 miles (145,000 km).
    Although not a required service, transmission fluid changing can help assure a trouble-free transmission. Likewise, changing the transmission filter at this time is also added insurance.
    1. Raise the car and support it securely on jackstands.
    The torque converters on some transmissions are equipped with drain plugs. Because it may take some time to drain the fluid from the converter, you may wish to follow that procedure at this time, then come back to the pan and filter removal.

    980822b.gif
    Before removing the transmission fluid pan, insure that the area is clean of dirt and debris

    2. Place a large drain pan under the transmission.

    378093c.gif
    Loosen all of the pan attaching bolts to within a few turns of complete removal


    1. Loosen all of the pan attaching bolts to within a few turns of complete removal, then carefully break the gasket seal allowing most of the fluid to drain over the edge of the pan.
    CAUTION DO NOT force the pan while breaking the gasket seal. DO NOT allow the pan flange to become bent or otherwise damaged.

    1. When fluid has drained to the level of the pan flange, remove the pan bolts and carefully lower the pan doing your best to drain the rest of the fluid into the drain pan.ea833e6.gif


    Once the pan is removed, discard the old gasket and insure that the mating surfaces are clean

    9aa0aea.gif
    Inspect this magnet inside of the pan for any large pieces of debris. A light gray coating is normal

    11c6ddb.gif
    Clean the pan thoroughly with a safe solvent and allow it to air dry

    5. Clean the transmission oil pan thoroughly using a safe solvent, then allow it to air dry. DO NOT use a cloth to dry the pan which might leave behind bits of lint. Discard the old pan gasket.

    22d9261.gif
    The transmission filter is secured by a mounting bolt (arrow). Some models may use two bolts

    097949a.gif
    Remove the filter mounting bolt ...


    d9f5189.gif
    ... then pull the filter free from the transmission

    6. If necessary, remove the Automatic Transmission Fluid (ATF) filter mounting bolts, then remove the filter by pulling it down and off of the valve body. Make sure any gaskets or seals are removed with the old filter. The transmission usually has one round seal and a rectangular gasket.

    7. Install the new oil filter screen making sure all gaskets or seals are in place, then secure using the retaining screws, if applicable.

    50f9d74.gif
    Install a new pan gasket


    8. Place a new gasket on the fluid pan, then install the pan to the transmission. Tighten the attaching bolts to 71-119 inch lbs. (8-13 Nm).

    34bd906.gif
    Fill the transmission with the proper amount of ATF

    9. Add three quarts (six quarts if the torque converter was drained) of fluid to the transmission through the filler tube.
    10. Remove the jackstands and carefully lower the vehicle.
    11. Start the engine and move the gear selector through all gears in the shift pattern. Allow the engine to reach normal operating temperature.
    12. Check the transmission fluid level. Add fluid, as necessary, to obtain the correct level.

    How do I replace the oil pan gasket on a 2001 GMC Yukon XL?


    Changing the oil pan gasket on a GMC Yukon XL is realtively simple, but does require removal of the exhaust pipe. You will need a new oil pan gasket and a new exhaust pipe flange gasket.
    Put the car on ramps or jacks to access the undercarriage.
    Remove the exhaust pipe by removing the 3 nuts holding the exhaust pipe flange to the exhaust manifold. These nuts often rust and prior application of penetrating oil may be required to remove them without damage. Once the pipe is unbolted, work the exhaust system loose from the hanging brackets. In most cases the entire system does not have to be removed since there is enough room to remove the pan with only the front hangers removed.
    Drain the oil from the engine
    Remove the 10 mm bolts holding the pan to the block.
    Remove the old gasket material and scrape any remaining gasket from the block and pan.
    Install the new gasket. Forma-Gasket or a similar product may be used in small quantities to "glue" the new gasket in place and prevent shifting while the pan is reattached to the block.
    Reinsall the 10 mm bolts in a cross pattern to ensure the gasket is compressed evenly. Do not overtighten the bolts.
    Replace the pipe to flange gasket between the exhaust pipe and the exhaust manifold with a new part.
    Reattach the exhuast pipe to the hangers.
    Install the 3 bolts connecting the pipe flange to the exhaust manifold.
    Fill the engine with oil.
