Ok so i have removed the pan and drained that fluid out but I want to drain all the fluid. I've done some research and found that the torque converter should have a drain plug but I can't find it. I can only assume that I'm looking in the right place since I've never changed atf fluid before. I took a shield off near the front of the transmission revealing what I think is the flex plate? Is this where I should be looking for the drain plug? It has been rotated completely and there is no sight of a plug. Forgive my ignorance lol.

 

Yes the drain plug is located there. It is a little hard to find lol. It will be in one of the holes and set back in. Some of these holes will have the converter mounting nuts in them and only one will have the plug. It took me about a half hour to locate the one that was in mine. This will still not drain all the fluid tho as the plug is not in the very bottom of the converter but up a little. There is a way to get it all out with the truck running but i have never done it myself. Someone will be on shortly that has tho I am sure. Also, the plugs are allen socket type. They are hard to see back in there.

 

Thank you very much. I finally found it. I don't think I'll worry about draining the last little bit out since it doesn't look too bad anyway.

 

Heres how I do it.

Never bothered with even finding that converter plug. This way gets everything out.


Drop the pan, change filter etc.

Reinstall pan, fill back up to capacity.

Start 'er up and let 'er run for a couple minutes. Shift through all the gears a couple times.

Now get a 5 gallon bucket and a piece of rubber hose.

Disconnect the trans feed line from the radiator (or aux cooler) and shove on the rubber line on that and aim the rubber line in the bucket. Tape the line to the lip of the bucket so it doesn't come out while it's flushing.

(to find the feed line, disconnect both lines to the radiator and start the engine for a second, witch ever line squirts out fluid is your feed line.)

Give a couple shots of compressed air through the radiator (or aux. cooler) to send all the old fluid and crap out of that and back to the transmission.


Put a good funnel on the transmission dipstick tube.


Now prepare at least 10 *OPEN* quarts of ATF ready, at easy hand reach.


Fire the engine up, and start pouring the ATF down the dipstick tube, and don't stop! As much fluid will be coming out as you are putting in.


When the fluid coming out and dumping into the bucket looks as nice and clean as the fluid you are dumping in, stop the engine.

Reconnect the feed line to the radiator (or aux. cooler). Make sure BOTH lines are well connected.

Start up engine and check level. Add as needed. Make sure level is correct.

Go for a good drive, when you get back, check level again and your done!



Simple as that! I do it every single year on my motorhome.

It's a good idea to be 2 people doing this, one sitting in the drivers seat of the vehicle waiting for commands by the person doing the work outside, just incase something happens that you need to turn off the engine quickly. You don't want your transmission to run dry.
