Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check and Replace Transmission Fluid

Check Fluid Level:
- Remove the transmission dipstick and wipe it clean.
- Reinsert it and pull it out to check the fluid level.
- Add fluid if necessary to reach the correct level.
Drain Old Fluid:
- Position a drain pan under the transmission pan.
- Remove the transmission pan bolts with a socket set and carefully lower the pan to drain the fluid.
- Clean the pan and magnet inside for metal shavings.
Replace Fluid:
- Replace the transmission filter (if applicable) according to manufacturer's specifications.
- Reinstall the transmission pan with a new gasket and torque bolts to manufacturer specifications (usually around 10-12 ft-lbs).
Refill Transmission Fluid:
- Using a funnel, add the recommended type and amount of transmission fluid through the dipstick tube.
- Start the engine and let it run for a few minutes, then cycle through all gears to circulate fluid.

3. Inspect and Replace Transmission Filter (if needed)

If the filter is clogged, replace it:
1. Remove any screws or bolts securing the filter.
2. Disconnect the filter from the transmission.
3. Install the new filter and secure it.

4. Check Electrical Connections

Inspect the TCM and transmission connectors for corrosion or damage.
Clean or replace connectors as necessary.

5. Test Drive

Reconnect the battery terminal and take the vehicle for a test drive to ensure the issue is resolved.
