Required materials:
* Transmission Fluid (ATF) for your transmission
* Flushing fluid for automatic transmission
*Transmission filter
* Automatic transmission pan gasket
* Funnel
* Set of keys
Instructions:
1. Preparing the car:
* Park the vehicle on a level surface and set the parking brake.
* Allow the engine to cool so that the transmission fluid is not hot.
2. Draining transmission fluid:
* Locate the automatic transmission oil pan under the vehicle.
* Unscrew the drain plug and drain the old transmission fluid into a previously prepared container.
* Replace the drain plug and tighten it to the required torque.
3. Installation of flushing fluid:
* Remove the automatic transmission oil pan and replace the oil pan gasket.
* Pour flushing fluid into the gearbox through the filler tube.
* Reinstall the oil pan and tighten the bolts to the required torque.
4. Flushing the gearbox:
* Start the engine and change gears, holding each gear for a few seconds.
* This will allow the flushing fluid to circulate inside the transmission and remove contaminants.
*Continue this process for 15-20 minutes.
5. Draining the flushing fluid:
*Repeat steps from section 2 to drain the flush fluid.
* Make sure it is dark red or brown in color, which indicates that it has collected dirt.
6. Filter replacement:
* Remove the oil pan and replace the transmission filter.
* Reinstall the oil pan and tighten the bolts to the required torque.
7. Refilling with transmission fluid:
* Fill the transmission with a sufficient amount of new transmission fluid through the filler tube.
* Check the fluid level using the dipstick and add it if necessary.
8. Completion of the procedure:
* Reinstall the filler tube and tighten the plug.
* Start the engine and check the transmission for leaks.
* Reset the transmission odometer (if required by your vehicle model).
