Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety.

2. Check and Replace Transmission Fluid

Tools Required: Socket set, funnel, transmission fluid.
Remove the transmission fluid drain plug and drain the old fluid into a pan.
Replace the drain plug and torque it to manufacturer specifications (refer to service manual).
Using a funnel, add new transmission fluid through the dipstick tube, ensuring the correct type (typically Toyota ATF WS).
Check the fluid level with the dipstick and add more if necessary.

3. Replace Transmission Filter

Tools Required: Socket set, new transmission filter, gasket, and transmission fluid.
Remove the transmission pan by unscrewing the bolts and carefully prying it off.
Replace the old filter with a new one, ensuring the gasket is properly seated.
Reinstall the transmission pan and torque the bolts to the specified values.
Refill the transmission with new fluid as described in the previous step.

4. Test Solenoids

Tools Required: Multimeter, socket set.
Locate the transmission solenoids, usually accessible by removing the transmission valve body.
Disconnect the electrical connectors and test the solenoids with a multimeter for resistance.
Replace any solenoids that do not meet specifications as per service manual guidelines.

5. Reconnect Battery and Test

Reconnect the battery terminals securely.
Start the vehicle and allow it to warm up.
Shift through all gears to ensure smooth operation and check for delayed engagement.
