I will be ordering Amsoil AT fluid soon for my 4R70W with the heavy duty trans cooler. I will be pulling the pan, draining the TC, and blowing out the cooler lines.

I've read that 13-14 quarts are required for a complete fluid change-out. However, with the larger factory cooler, would I need a tad more...say 15 quarts?

Thanks in advance!
Kevin

 

Maybe part of one quart for the cooler. Certainly not two additional quarts.

Mark,
Thanks for your reply. Guess I'll 15 quarts to be sure!

 

Make sure you fill the last few quarts slowly so you don't overfill it. Without flushing the cooler but draining the TC I put in 12 quarts I think because there was still a quart or so in the lines.

 

Thanks P!...I will take your advice.

 

Put about 6 quarts in, start it up for 30 seconds, fill another 2-3 quarts, run 30 seconds. Keep doing this till you get to 10-11 quarts. Then slowly fill it. Run it for a few minutes, check the level. If you overfill it's the most convenient to pull the TC plug and drain it slowly there instead of messing with the pan or insert a tube into the filler neck/dipstick and vacuum some out.

After going through all th information here I could...I went and changed the fluid and filter in the tranny. Only problem is there was no drain bolt in the torque converter.

Any ideas on how to drain it without a drain plug?

Greg,

With the tranny in neutral (emergency brake on and the front slightly jacked up), did you slowing turn the engine with a 1/2" breaker bar on the crankshaft dampner nut while feeling, or looking for the drain plug on the torque converter? If so, and you could not find it, they must have redesigned the TC for 2002 and saved 22 cents!

I was able to use my right arm on the breaker bar to turn the engine over and used my left to feel for the plug...quickly found mine.

Tried looking for the bolt for a long time... breaker bar...starter...even ran the engine while lightly dragging a wood stiring stick across the TC through the inspection port (to feel for it as I might have missed it using the previous methid.)

There is definatly no drain bolt for my 2002.

After looking around and reading a link to the Superduty site...apparently there are others without the drain plug....

How to drain it: disconnect the lines rinning to the cooler and put them in a bucket. Idle the engine until some air comes out of the tube. Immediatly shut off the engine (this will get most of the fluid in the pan as well making it easier to remove). I guess this method is in the Ford service manual...

-Greg

 

Ford... for removing the drain bolt... YOU SUCK!

 

The drain plug was deleted starting in August, 2001.

You can still change all the fluid, but it's not quite as easy. Here is a link to a procedure for a 4R100, but all transmissions are similar for this:
