HELP Accidentally drained tranny fluid

Tried to do a first time oil change on the truck.

Thought I drained the oil, but in reality I drained the transmission fluid. My brain was on autopilot and I added 5.2 quarts to the oil fill up. Then I changed the oil filter. Went and saw the oil and drained and it was clearly tranny fluid

So the oil level is at double (10 quarts) and the transmission fluid is empty. Yes, I know I’m an idiot.

what’s should I do??

 

Drain the engine oil and fill with 5 qts.

Get a hand pump and some ATF and start filling the trans. First with the engine off, then with the engine running. Fill until the fluid runs out the check plug.

There's threads around here and videos on YT

 

Trans fluid has a special procedure for filling properly. Has to be within a certain temperature range. That's assuming you have an Auto transmission.

Engine oil is easy. Drain all of it and start over by purchasing more fresh oil.

 

I could have sworn this exact thread was made about a week ago.

 

It was.

Thanks for all the help everyone. I will tackle this job tomorrow morning

 

At least you caught it before you drove it and did damage, some weren't so lucky.

For a quick and easy estimate, put your old transmission fluid into a big measuring cup or pitcher and you'll know how much came out. Then put same amount of new fluid in.

 

HALP!!!

 

I find it shocking how often this happens.

 

I was going to suggest a sticky...

 

Thanks for clarifying

 

Not the first to do it. Won't be the last.
Drain engine oil, fill to proper level.
Using the procedure here on TW, refill and check level of trans fluid.
Get a paint marker and label the pans Eng/Trans. Not a bad idea to mark the mileage on the trans pan so you know when you did a dump & fill on it.

 

The correct temp range is about 100-110 degs. You can use the dlc check procedure, I usually just take temp at the pan with a temp gun so I don't have to go up on a ladder or crawl out from under the truck

 

Drain Tranny , then replace with 3qts 6 ozs ATF . that is what comes out . you will be fine. and drain Engine oil and refill with 5 Qts oil ! SHIT Happens ! LOL

 

Here's a link (one of many) for a thread discussing the refilling the trans. The attached pdf is a good read with illustrations of the fill/overflow plugs with a side cut away view of the pan. It also goes into the process filling and checking for the correct level of transmission fluid.

Step away from the truck and nobodies transmission will get hurt.

 

Lots of FNGs trying to save some money the hard way.

 

So I followed every thread and video to a T and I cant get the transmission fluid to the right temperature

after 20+ Minutes of idling, the ATF light never shows up again. It flashes for 1.5 seconds after I do the shift maneuver, leading to me believe I am in the check mode. Any ideas?
