why does my Toyota Tacoma N300 (2016-Present) have a delay when I shift gears?

Solution

1. Preparation

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

2. Check and Replace Transmission Fluid

• Sub-steps:
  1. Locate the transmission dipstick or fill plug.
  2. Remove the dipstick and check the fluid level; if low, add the correct type of transmission fluid (Toyota Type T-IV or equivalent).
  3. If the fluid is dark or smells burnt, drain the old fluid from the transmission pan.
  4. Replace the filter if applicable, and reinstall the transmission pan with new gasket.
  5. Refill the transmission with the correct amount of new fluid.

3. Inspect and Replace Transmission Solenoids

• Sub-steps:
  1. Remove the transmission pan if it hasn't been done already.
  2. Locate the transmission solenoids and disconnect the electrical connectors.
  3. Remove the solenoids by unscrewing them from their mounting positions.
  4. Install the new solenoids in reverse order and reconnect the electrical connectors.
  5. Replace the transmission pan and refill with fluid.

4. Reprogram TCM (if necessary)

• Sub-steps:
  1. Reconnect the battery.
  2. Use a scan tool to check for software updates for the TCM.
  3. Follow the manufacturer's instructions to reprogram or reset the TCM if updates are available.
