1. Preparation

Tools Required: OBD-II scanner, socket set, transmission fluid dipstick, multimeter, jack and jack stands.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to ensure safety while working on electrical components.

2. Check and Replace Transmission Fluid

Locate the transmission fluid dipstick or fill plug.
Remove the dipstick and check the fluid level; add fluid if necessary.
If the fluid is low, inspect for leaks and replace any damaged seals.
If the fluid is discolored or burnt, drain the old fluid and replace it with new manufacturer-recommended fluid.
- Fluid Type: Ford Mercon ULV or equivalent.

3. Inspect and Repair Transmission Linkage

Examine the transmission linkage for any signs of damage or disconnection.
Reconnect any loose components and tighten with a socket set.
If components are worn, replace them as needed.

4. Test Throttle Position Sensors

Use a multimeter to test the throttle position sensor and accelerator pedal position sensor.
Compare the readings to manufacturer specifications; replace any faulty sensors.
- Calibration: Follow manufacturer guidelines to calibrate new sensors.

5. Check Drive Axles and Differential

Inspect the drive axles for any visible damage or wear.
If necessary, remove the affected axle using a socket set and replace it with a new one.
Check the differential fluid level and replace if low or contaminated.
