•Increased RPMs before the vehicle moves

Diagnostic Steps

1
Scan for error codes using an OBD-II scanner to check for transmission-related faults.
2
Inspect transmission fluid level and condition; look for discoloration or burnt smell.
3
Check for any signs of external transmission fluid leaks.
4
Test the transmission control module (TCM) for proper function and communication with other systems.
5
Examine the transmission linkage for proper adjustment and function.
6
Inspect the battery voltage to ensure it is within acceptable limits, as low voltage can affect electronic controls.

2. Insert the dipstick back into the tube, then remove it again to check the fluid level.
3. If fluid is low, add the recommended transmission fluid type (refer to the owner’s manual).
4. If fluid is dark or has a burnt smell, drain and replace the fluid.
  - Tools Required: Transmission fluid pump, drain pan, funnel.
  - Fluid Type: Ford Mercon LV or equivalent.

3. Inspect and Adjust Transmission Linkage

Sub-steps:
1. Locate the transmission linkage under the vehicle.
2. Identify any misalignment or wear in the linkage components.
3. Adjust the linkage according to the manufacturer specifications to ensure proper engagement.

4. Replace Transmission Control Module (if necessary)

Sub-steps:
