Does transmission fluid read when high in cold?
The reason for checking when both hot and cold is transmission fluid expands as it is heated. Transmission fluid expands and keeps expanding the hotter it gets. Dipsticks are calibrated to “normal” hot operating temperature (i.e., the 10 mile suggested drive; longer in winter).

How long does it take to warm up transmission fluid?

Why does my transmission heat up in hot weather?
Hot weather contributes to an overheating transmission by raising the resting fluid temperature, so it’s warmer than normal from the get-go. Combined with city driving, your transmission fluid is bound to heat up and wear out sooner, so it pays to check it frequently.
How can you tell if your transmission is overheating?
Transmission fluid is the lifeblood of your transmission. It cools and lubricates the many moving parts of the transmission. You can check fluid levels by pulling the transmission dipstick. Refer to your owner’s manual for location of the dipstick and the right levels to look for. If you have low fluid levels, you’ll need to add more fluid.
Why is the transmission fluid in my car so low?
Always use the manufacturer-recommended automatic transmission fluid. There is essentially one primary reason your transmission fluid is low, and it’s leakage. The fluid is finding its way out of the system and into our big world. Here are a few places the leak could occur:
