I recently changed my oil on my 17 Tacoma 4x4. The manual calls for 6.2 quarts with the transmission cooler. I always drain my vehicles semi warm to get the oil. I keep getting a reading that says i'm 1/4" of a inch high. Not really much at all. I put back roughly 6.2 measuring the back of the bottle. I check it by starting it up. Let it cool down for 5-10 mins with the dipstick out and wipe and recheck. The level looks like this below. Maybe even a bit less.
