Solution

1. Fluid Inspection and Replacement

Check Fluid Level:
- Ensure the vehicle is on level ground.
- Remove the dipstick, wipe it clean, and reinsert it to check the fluid level.
Fluid Change:
- If the fluid is low or dirty, drain the old fluid using a pan.
- Replace with OEM transmission fluid as specified in the owner's manual.
- Recheck the level after adding fluid.

2. Transmission Control Module (TCM) Inspection

Inspect Connections:
- Disconnect the TCM connector and visually inspect for damage or corrosion.
Reset TCM:
- If applicable, perform a reset by disconnecting the battery for about 15 minutes.
Reinstall:
- Reconnect the TCM ensuring a secure fit.

3. Solenoid Testing and Replacement

Access the Solenoids:
- Remove the transmission pan and filter to access the solenoids.
Test Solenoids:
- Use a multimeter to check for proper resistance as per manufacturer specifications.
Replace if Necessary:
- If any solenoids are faulty, replace them with new ones and reinstall the pan.

4. Engine Mount Inspection and Replacement

Visual Inspection:
- Check the engine mounts for cracks, separation, or excessive wear.
Replace Mounts:
- If damaged, use a jack to support the engine, remove the old mounts, and install new OEM mounts. Torque to manufacturer specifications.
