Transmission Pan

Start the automatic transmission fluid filter servicing operation by placing the vehicle into NEUTRAL gear and hoisting it before beginning. Remove the heated oxygen sensor connectors which connect to the transmission pan rail front section before unclipping the retaining wire from the right side of the pan rail. Remove the drain plug to drain the fluid and then remove the transmission fluid pan together with its gasket. Discard the old transmission fluid filter before cleaning and inspecting the transmission fluid pan along with the magnet inside. Apply clean automatic transmission fluid to new transmission filter O-ring seals before securing it with screws that should receive torque of 10 Nm (89 lb-in). Position and secure the fluid pan magnet inside the transmission fluid pan while installing both components before screwing the pan in place with loose threads and then tightening in a crisscross pattern to 10 Nm (89 lb-in). Reattach the drain plug while torquing it to 26 Nm (19 lb-ft) then reconnect the heated oxygen sensor connectors together with the wire retaining clip. Before checking the fluid level use a wrench to hold the drain plug while removing the liquid indicator plug with a 3/16-inch Allen key.

Start fluid pan gasket filter servicing by applying automatic transmission fluid to the filter seals followed by proper positioning of seals onto the filter. The transmission fluid pan gasket is reusable when cleaned properly since no damage is present it can be utilized again. Installation of a new transmission fluid filter must always occur first. Place the vehicle in NEUTRAL position on the hoist then systematically detach components starting from the end. The installation process follows backward steps from removal while you should fill the transmission with fluid at its proper level. First detach the connectors from the Heated Oxygen Sensor (H02S) before extracting its wire retaining clip from the transmission pan rail on the right side. Detach the H02S connector from the transmission pan rail front section before placing it on the workstation. Reinstall the transmission fluid filter while relubricating its seals and then replace the filter element in the transmission pan. Then next secure the transmission fluid pan by setting its screws at first without full tightening. Begin by crisscrossing the screw installation and return the H02S connector to the transmission pan rail's front side. Attach H02S connectors while installing the sensor wire retaining clip on the right side of the transmission pan rail.

Service operations begin with position of the vehicle in NEUTRAL gear while located on a hoist. You need to drain transmission fluid using drain plug removal while discarding the gasket. The right-hand pan rail requires removal of heated oxygen sensor (HO2S) connectors and retaining clip which needs storage in safe place. Detach the HO2S connector which is located at the front of the transmission pan rail. Before reuse decide whether the transmission fluid pan gasket shows any damage. A sound gasket can stay in service. The following step involves removing the transmission fluid pan together with its gasket before disposing of the transmission fluid filter. The first step for installation involves cleaning both the transmission fluid pan as well as its magnet. Nitrogen lubrication is applied to the O-ring seals of the new transmission fluid filter to stop damage and provided appropriate seating. Mount the filter by screwing it in place until achieving 10 Nm (89 lb-in) of torque. Reinsert the fluid pan magnet into the transmission fluid pan before installing the pan with its gasket and loosely attaching its screws. Secure the screws by crisscrossing the pattern at 11 Nm (8 lb-ft). The HO2S connector should be reconnected to the transmission pan rail front while the sensor wire retaining clip needs to be installed to the right pan rail side. Use a new gasket on the drain plug before tightening it to 26 Nm (19 lb-ft). You should hold the drain plug with a wrench when removing the fluid level indicator plug using a 3/16-inch Allen key to check the fluid level of the system.

Before servicing the transmission fluid pan, gasket and filter you must lubricate their seals with new automatic transmission fluid then set the seals precisely onto the filter. The transmission fluid pan gasket can be reused unless showing damage where you need to inspect it before reusing it. The service requires installing an entirely new transmission filter. Set the vehicle to NEUTRAL position then mount it on a hoisting system before removing the components according to their installation order. Follow the reverse order for installation while keeping the transmission partially filled. Use tools to disconnect heated oxygen sensor connectors along with extracting the sensor wire retaining clip from the right side of the transmission pan rail. Move and secure the heated oxygen sensor connector which is attached to the front position of the transmission pan rail. Lubricate the fluid filter seals twice before installing the transmission fluid filter. Following installation of the transmission fluid pan alongside its gasket it is necessary to install screws loosely before completing a crisscross tightening of all screws. Secure the heated oxygen sensor connector at the transmission pan rail front while connecting all heated oxygen sensor connectors and installing the sensor wire retaining clip at the right side of the pan rail.

A proper servicing approach for the fluid pan gasket and filter starts with cleaning the automatic transmission fluid before applying it onto the filter seals for protection from damage during installation. The transmission fluid pan gasket can be used again after cleaning and proper inspection to reuse if it lacks damage. You should install a fresh transmission fluid filter. Remove the drain plug from the vehicle in NEUTRAL position when the vehicle sits on a hoist to drain fluid. Separate the heated oxygen sensor (HO2S) connectors and its retaining clip from the right-hand pan rail before moving on to disconnect the HO2S connector installed at the front of the transmission pan rail. Keep the connectors to one side. Take off the transmission fluid pan with its gasket and dispose of the transmission fluid filter. Before installation check the transmission fluid pan along with magnet and apply clean automatic transmission fluid to the transmission fluid filter O-ring seals before placing them in their correct positions. Fasten the transmission fluid filter using screws that should be tightened to 10 Nm (89 inch lbs.). Lay the fluid pan magnet into the transmission fluid pan before installing both pan and gasket while leaving the screws loose. The screws on the transmission pan should get tightened using an 11 Nm (8 ft. lbs.) torque setting when implemented according to a crisscross pattern. Reinstall the HO2S connector on the transmission pan rail front section while connecting the HO2S connector alongside securing the sensor wire retaining clip on the right side of the pan rail. Fasten the drain plug at 26 Nm by using torque wrenches and attach it until it reaches 19 ft. lbs. Holding the drain plug with a wrench is required before pulling out the fluid level indicator plug that can be unplugged with a 3/16-inch Allen key. Perform the fluid level examination as the conclusion.

Carry out the fluid level check.

Tighten the screws in a crisscross sequence.

Reconnect the HO2S connector at the front of the pan rail and secure the sensor wire retaining clip on the right side.

Yes, the transmission fluid pan gasket is reusable; clean and inspect it for damage, and if it is not damaged, it should be reused.

Reinstall the HO2S wire connector retainers on the transmission fluid pan rails and reconnect the sensors.

Carry out a fluid level check.
