Checking transmission fluid cold??
Hi Guys
I was taught to check transmission fluid when the engine is up to normal running temps, however last time I checked mine, I noticed that on one side of the dipstick it says HOT and the other side COLD.
Am I just a "dipstick" or can you actually check it cold using the other side as a gauge?
Cheers

After I do a ATF drain and fill on any vehicle, I always check it hot and also check it for a few days after. I would think that if the car has been driven for months and the ATF is at the cold reading or a little higher, then the fluid level is fine.

Paul, you know how many times I've checked mine in 6 years? Once! Quit being neurotic and enjoy the car! If it drives fine and shifts fine, it's fine. You're going to wear the dipstick out!😃

I agree with most of the responses here that the Hot check is the most accurate and is the one to be relied on.
One thing not mentioned about the Cold check is that during service it does two things;
1. Ensure there is enough fluid for initial start-up.
2. Prevent overfilling.
Some transmissions can be damaged if too much fluid is installed.
Filling to the Cold line prevents overfilling and should indicate a correct Hot reading once the fluid is warm and has expanded.
