my Toyota RAV4 won't shift into gear, what could be causing this

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface.
• Disconnect the battery to prevent electrical shorts.

2. Check and Replace Transmission Fluid

• Sub-steps:
  • Locate the transmission dipstick (for automatic) or access the transmission pan (for manual).
  • Remove the dipstick or drain pan.
  • Check fluid level and condition. If low or burnt, proceed to replace.
  • Drain the old fluid into a suitable container.
  • Replace with the appropriate transmission fluid as per the manufacturer’s specifications.

3. Inspect and Repair Transmission Linkage

• Sub-steps:
  • Locate the transmission linkage (usually connected to the shifter).
  • Visually inspect for any signs of wear or damage.
  • If damaged, replace the linkage with a new part.
  • Adjust the linkage according to manufacturer specifications if misaligned.

4. Inspect and Replace Transmission Filter (if applicable)

• Sub-steps:
  • Remove the transmission pan (if equipped) by unscrewing the bolts.
  • Carefully lower the pan and remove the old filter.
  • Install the new filter and reattach the pan with a new gasket.
  • Torque the pan bolts to manufacturer specifications.

5. Reconnect Battery and Test

• Reconnect the battery terminals.
• Start the engine and test the transmission by attempting to shift through all gears.
