Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, multimeter, transmission fluid pump.
Ensure the vehicle is on a level surface and securely supported with jack stands.
Disconnect the battery to prevent electrical shorts.

2. Check and Replace Transmission Fluid

Remove the transmission dipstick and check the fluid level.
If low, add fluid; if burnt or discolored, proceed to replacement.
Place a drain pan under the transmission pan.
Remove the transmission pan bolts using a socket set.
Carefully lower the pan and remove the old gasket.
Drain the old fluid completely and clean the pan.
Install a new transmission filter if applicable.
Replace the gasket, ensuring it is seated properly.
Reinstall the transmission pan and torque the bolts to manufacturer specifications (typically 8-10 ft-lbs).

3. Inspect and Test Solenoids

Locate the transmission solenoids according to the vehicle manual.
Disconnect the wiring harness from each solenoid.
Use a multimeter to test resistance; compare values to manufacturer specifications.
Replace any faulty solenoids with new parts.

4. Repair or Replace TCM

Inspect the TCM for any signs of damage or corrosion.
Check wiring connections for integrity.
If necessary, replace the TCM with a compatible unit and reprogram as needed.
