What temperature of the transmission I need to check the transmission fluid level?

Here is how to check the transmission fluid level and the type of fluid used. The engine should be warm while checking the fluid.

Fluid Types

Fluid type:. Toyota Genuine ATF Type T-IV

Change Automatic Transmission Fluid Only As Necessary.

Generally, it is necessary to change automatic transmission fluid only if your vehicle is driven under one of the Special Operating Conditions listed under one of the Scheduled Maintenance Guide or Owner's Manual Supplement.

When changing the automatic transmission fluid, use only "Toyota Genuine ATF Type T-IV" (ATF JWS3309 or NWS6500) to aid in ensuring optimum transmission performance.

Notice: Using automatic transmission fluid other than "Toyota Genuine ATF Type T-IV" may cause deterioration in shift quality, locking up of your transmission accompanied by vibration, and ultimately damage the automatic transmission of your vehicle.

For a 2007 Toyota Corolla, the transmission fluid should be checked at a warm operating temperature, ideally around 104°F to 113°F (40°C to 45°C).

There is conflicting information about this, I would drive the car, or just start the engine and allow it to get to operating temperature and then check the fluid level.
