my Ford F-150 12th Generation (2009-2014) won't go into gear what's the issue

Solution

1. Preparation

• Gather tools and parts needed for the repair.
• Ensure the vehicle is parked on a level surface and the engine is off.
• Disconnect the battery to avoid electrical shorts.

2. Check and Replace Transmission Fluid

• Tools Required: Transmission fluid pump, funnel, socket set, drain pan.
• Remove the transmission pan using a socket wrench.
• Allow the old fluid to drain completely into a pan.
• Inspect the filter and replace it if necessary.
• Reinstall the pan with a new gasket and torque bolts to factory specifications (typically 10-12 ft-lbs).
• Refill the transmission with the manufacturer-recommended fluid type (check owner's manual).

3. Inspect and Adjust Transmission Linkage

• Tools Required: Wrench set, screwdriver.
• Visually inspect the transmission linkage for any disconnections or damage.
• If misaligned, loosen the adjusting nuts and realign the linkage as per manufacturer specifications.
• Tighten the nuts securely after adjustment.

4. Replace Brake Switch (if faulty)

• Tools Required: Socket set, wire connectors.
• Locate the brake switch, typically near the brake pedal.
• Disconnect the wiring harness from the switch.
• Remove the switch using a socket wrench and replace it with a new one.
• Reconnect the wiring harness and test the operation.
