Over the last few days I've taken the lower auto trans oil pan off to replace the ATF fluid temp sensor. I've let the fluid drain for 3 days. A total of 8 quarts came out.
I've finished the job and refilled the trans with 4 quarts to test drive. With the engine warm I'm not getting an fluid on the stick.

Do I need to refill with 8 quarts total to match what came out or just 1 more qt at a time and check the stick?

Thanks.

 

add 4 more quarts the 4 you put in

 

Run the transmission through the gears with your foot on the brake a few times and then check the fluid...I'm guessing you'll need to add some.

I don't know how you managed to get 8 qts. total as according to the service manual an ATF dry fill calls for 7.2 US quart.
