What is the correct temperature for checking ATF level?

The OP probably drives some sort of Suzuki

Is Suzuki ATF 3317 just rebranded JWS3309?

This mysterious Suzuki OEM fluid has no specifications listed anywhere and the manual says "Use Suzuki ATF 3317 or Mobil ATF 3309". Just trying to find some more details about the ATF 3317 ATF.

I check the fluid level multiple times after a cooler line exchange.

Adding small amounts until the fluid levels are in the temperature ranges on the dipstick. Verifying with my infrared temp meter.

I also measure the temperature of the new fluid and wait until it has reached ambient temperature. The fluid is stored in the stone basement of our 1934 home.

I want the new and old fluid to be as close in temperature as possible. This makes the fluid adjustment much easier.

It takes a while and is best done when the OAT is not extreme.
