my Toyota Camry XV40 has a rough transmission shift

Solution

1. Preparation

• Tools Required: OBD-II scanner, socket set, transmission fluid pump, torque wrench, funnel, safety glasses, gloves.
• Ensure the vehicle is on a level surface and the engine is cool. Disconnect the battery before working on electrical systems.

2. Transmission Fluid Change

1. Drain Old Fluid:

   • Locate the transmission drain plug and place a drain pan underneath.
   • Remove the drain plug and allow the fluid to completely drain.
   • Reinstall the drain plug and torque to the manufacturer's specification (usually around 30 ft-lbs).

2. Replace Transmission Filter:

   • Remove the transmission pan by unscrewing the bolts.
   • Carefully detach the pan and clean any debris or old gasket material.
   • Remove the old filter and install a new one, ensuring it is seated properly.

3. Reinstall Pan:

   • Place a new gasket on the transmission pan and reinstall it.
   • Torque the pan bolts to the manufacturer's specifications (typically 12-15 ft-lbs).

3. Refill Transmission Fluid

1. Add New Fluid:

   • Use a funnel to pour new transmission fluid into the dipstick tube (consult the owner's manual for the specific type and quantity).
   • Start the engine and allow it to idle for a few minutes.

2. Check Fluid Level:

   • With the engine running, shift through all gears and return to park.
   • Check the fluid level with the dipstick and add more fluid if necessary until it reaches the full mark.
