Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, torque wrench, multimeter, transmission fluid, funnel, and a drain pan.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Disconnect the battery to avoid any electrical issues.

2. Check and Replace Transmission Fluid

Fluid Level Check
1. Locate the transmission dipstick (if applicable) or access the transmission fill plug.
2. Remove the dipstick, wipe clean, reinsert, and check the fluid level.
Fluid Replacement
1. If fluid is low or burnt, drain the transmission fluid by removing the drain plug or pan.
2. Replace the transmission filter by removing the pan (if applicable) and installing a new filter.
3. Reinstall the pan and torque bolts to manufacturer specifications.
4. Refill the transmission with the correct type of fluid specified in the owner’s manual using a funnel.

3. Inspect and Replace Transmission Solenoids

Remove the transmission pan if not already done during fluid replacement.
Disconnect the electrical connectors from the solenoids.
Remove the solenoids from their housing.
Install new solenoids and reconnect the electrical connectors.
Reinstall the transmission pan and ensure it's properly torqued.

4. Inspect and Replace Transmission Mounts

Use a jack to support the transmission.
Remove the bolts securing the transmission mount to the frame and the transmission.
Replace with new mounts and torque bolts to manufacturer specifications.
