Solution

1. Preparation

Gather tools and parts.
Park the vehicle on a level surface and set the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Check and Top Up Transmission Fluid

Tools Required: Transmission dipstick, funnel, new transmission fluid (check owner’s manual for specification).
Remove the dipstick and check fluid level. If low, use a funnel to add the appropriate type of transmission fluid until it reaches the full mark.
Safety Warning: Ensure the vehicle is off and the engine is cool before checking or adding fluid.

3. Replace Transmission Fluid and Filter

Tools Required: Socket set, drain pan, new transmission filter, new transmission fluid.
Place a drain pan under the transmission pan, remove the pan bolts, and allow the old fluid to drain completely.
Remove the old filter and install the new one, ensuring it is seated properly.
Reinstall the transmission pan with a new gasket and torque the bolts to the manufacturer’s specifications (usually around 8-10 Nm).
Refill the transmission with the new transmission fluid through the dipstick tube.

4. Inspect and Repair Electrical Connections

Tools Required: Multimeter, wiring harness repair kit.
Check the wiring harness connected to the TCM for frays or corrosion.
Use a multimeter to ensure the TCM is receiving the correct voltage.
Repair any damaged wires or connections as necessary.

5. Test Transmission Solenoids

Tools Required: Multimeter.
Disconnect the electrical connector from each solenoid and test for resistance according to manufacturer specifications.
Replace any solenoids that do not meet the specified resistance.
