Title: Addressing Rough Transmission Shifts in a Toyota Camry XV70 (2018-2024)

Repair Instructions

Step 1: Transmission Fluid Change

If fluid is dirty or low:

Gather Tools and Materials:
- Transmission fluid (consult owner’s manual for specifications).
- Transmission fluid pan.
- Socket set and wrench.
- Funnel.
- Gasket or RTV sealant (if necessary).
Lift the Vehicle:
- Use a hydraulic jack to lift the front of the vehicle and secure it with jack stands.
Drain Old Fluid:
- Place the transmission fluid pan under the transmission pan.
- Remove the transmission pan bolts using the socket set.
- Allow the old fluid to drain completely into the pan.
Replace Filter (if applicable):
- If the transmission has a filter, remove it and replace it with a new one. Ensure the new filter is seated correctly.
Clean the Pan:
- Wipe down the transmission pan and remove the old gasket material.
- If using RTV, apply a thin bead around the pan where it will seal.
Reinstall the Pan:
- Reattach the transmission pan and tighten the bolts in a criss-cross pattern to ensure even sealing.
Refill with New Fluid:
- Using a funnel, refill the transmission with the appropriate amount of new ATF through the dipstick tube.
Check Level Again:
- Start the engine and allow it to warm up. Shift through all gears.
- Check the fluid level again and top off if necessary.

Step 2: Transmission Control Module (TCM) Reset

If DTCs indicate a TCM issue:

Disconnect the Battery:
- Use a wrench to disconnect the negative terminal of the battery and wait for about 10 minutes.
Reconnect Battery:
- Reconnect the negative terminal.
Recheck for DTCs:
- Use the OBD-II scanner to check if any codes remain after the reset.

Step 3: Consult a Professional

If the rough shifting persists after fluid changes and resets:

It may be necessary to consult a professional technician or dealership, as further diagnostics may involve checking the TCM, solenoids, or internal components of the transmission.

Conclusion

Regular maintenance of transmission fluid can prevent rough shifts in your Toyota Camry XV70. If problems persist after basic checks and fluid changes, seeking professional assistance is recommended. Always refer to the vehicle’s service manual for specific instructions and specifications.
