Change tranny fluid when cold?

I know you have to check tranny fluid when hot and immediately after turning off the engine. However, is there any reason not to change the fluid when cold?

I ask because my understanding is that it can take a while for all the tranny fluid to drain down after turning off the engine. Seems like you could be sure to get more out if sucking it out cold. Is there some other reason to suck it out hot that I am missing?

No advantage to changing it when its warm other than it is easier to pull out the fluid. For the engine oil, I recommend getting it warm so it doesn't take 2 weeks to drain.

What he said......hot transmission fluid is easier to extract/takes less time with the vacuum extractor. Cold fluid moves slow. Same with oil!

Changed my transmission fluid yesterday -- cold. My transmission uses Dexron III/Mercon, and that stuff appears to have the same viscosity cold as it does warm. It sucked out very easily.

I like your style. If it's really cold do you recommend having two beers? 🍺
