3. If fluid is dirty or burnt, drain the old fluid using a fluid extractor from the transmission pan.
4. Replace with new, manufacturer-approved transmission fluid.
Tools Required: Fluid extractor, funnel, transmission fluid.

3. Inspect and Replace Transmission Filter

Sub-steps:
1. Remove the transmission pan using a socket set.
2. Take out the old transmission filter and replace it with a new one.
3. Clean the transmission pan and install a new gasket before reassembling.
Tools Required: Socket set, new transmission filter, new gasket.

4. Test Transmission Solenoids

Sub-steps:
1. Disconnect the wiring harness from the transmission solenoids.
2. Use a multimeter to test for resistance according to manufacturer specifications.
3. Replace any faulty solenoids.
Tools Required: Multimeter.

5. Final Assembly and Fluid Check

Sub-steps:
1. Reassemble the transmission pan and ensure all bolts are torqued to manufacturer specifications.
2. Reconnect the battery and start the engine.
3. Cycle through the gears and check for fluid leaks.
