Replacement procedure:
1. Preparation:
* Place the vehicle on a level surface and secure it with the parking brake.
* Allow the engine to cool.
* Gather all necessary tools and materials.
2. Draining ATF fluid:
* Locate the drain plug at the bottom of the automatic transmission pan.
* Place a drain pan under the plug.
* Unscrew the drain plug and drain the ATF into the drain pan.
* While the ATF is draining, clean the drain plug and install a new gasket.
3. Removing the automatic transmission pan:
* Unscrew the bolts around the perimeter of the automatic transmission pan.
* Carefully remove the pan from the automatic transmission housing using a crowbar or flathead screwdriver.
* Allow any remaining ATF fluid to drain from the pan.
4. Replacing solenoids:
* Locate the solenoids in the automatic transmission housing. They usually have electrical connectors and are secured with bolts.
* Disconnect the electrical connectors.
* Unscrew the solenoid mounting bolts.
*Remove old solenoids and install new ones.
* Tighten the solenoid mounting bolts using a torque wrench to the torque specified in the repair manual.
* Connect the electrical connectors.
5. Installing the automatic transmission pan:
* Install the gasket on the automatic transmission pan.
* Place the pan on the automatic transmission housing and tighten the mounting bolts.
* Tighten the pan mounting bolts using a torque wrench according to the torque specified in the repair manual.
6. Filling with ATF fluid:
* Locate the filler plug on the side of the automatic transmission housing.
* Pour in new ATF through the filler plug.
* Refill with the same amount of ATF that was previously drained.
* Install the filler plug.
7. Checking the ATF fluid level:
* Start the engine and let it run for a few minutes.
* Shift the gearshift lever to each position and return it to park mode.
* Remove the ATF dipstick and check the fluid level.
* If necessary, add ATF fluid to the “full” mark on the dipstick.
8. Final stage:
* Reset the transmission adaptation counter according to the instructions in the repair manual.
* Check the vehicle for ATF leaks.
* Take a test drive and make sure the automatic transmission is working properly.
Warnings:
* Be careful when handling ATF fluid as it can be very hot.
* Do not overtighten the solenoid mounting bolts, as this may damage the automatic transmission housing.
*Only use ATF fluid recommended by the manufacturer for your vehicle model.
