How To Get More Than 8-7 Quarts

I change my transmission fluid on Saturday and I wanted to get more than the usual 8-7 quarts of fluid from the pan and external filter.








These are the tools that I used.
A breaker bar with extender
air hose
10mm socket and extender for the pan bolts
a universal socket joint
you can use a 13mm socket but I chose to use 1/2" socket because it had a tighter fit on the pan drain bolt
brake cleaner
19mm socket for the external filter and if you have a 12 toothed socket, use it, that would be better than a 32 toothed socket for the external filter because it is hard to get off.


Here is how I got more fluid out.

The first thing after I removed the external filter, pan, filter in the pan and let it sit for 20 min, is start the truck and let it sit running for 15 seconds. Allot more fluid came out.

Then I did this below.


After I took off the pan and removed the filter, I cut the filter tube off. I used this along with a grommet and the air hose. I put it back into the valve body and push out more fluid. I got ~1 quart out doing this.





With the external filter off I use air pressure to push fluid out of the cooler. The fluid came out of the rectangle opening on the side. Fluid also came out of the valve body area. This and letting the truck run for 15 seconds really got the extra fluid out.

This is what got me at total of 13 quarts removed from the system.

Here are some other things that I did.








Before I change the fluid, I had two 50 LB magnets on the pan for ~15,000 miles.





Looks like they worked.




Magnet around the bolt.




Now After I cleaned the pan I removed the stock magnet and used the larger one from an extra 50 LB magnet.







This is just to compare the size. I did not leave the stock(smaller) magnet there. The stock was not used.


I also painted the pan and external filter housing :)













I replaced both filters. I got them at Dieselfiltersonline.com
I put grease on the threads of the external filter housing before I put it on so that it will be easer to remove the next time around.



Not including painting, It took ~ 20 min to get the extra fluid out. I put in a total of almost 13 quarts of LV. The level sits at the max line.


Another thing is when the transmission temp hit 170* the level drooped. This is because of the thermostat in the transmission opening, allowing the fluid to get to the empty oil cooler. This drooped me ~ 3 quarts.
I used a piece of card board on the lower half of the radiator to get the trans temps up. The highest temp was 190* with light driving.

Re: How To Get More Than 8-7 Quarts

Waaaaaay too much effort and risk IMO. What if you bounced one of those 50 lb magnets off while driving? What if you ran the motor too long with the pan open and it ran dry? I'd either pay someone to flush the transmission or

1) Drain pan (6-8 qts)
2) Top off with new ATF
3) Drive for 20 min
4) Drain pan (6-8 qts)
5) Replace external filter
6) Top off with new ATF

Safe, simple, and fast.

Just my $.02

Re: How To Get More Than 8-7 Quarts

I think you did an excellent job. Bumping the motor may have been a touch safer than an idle, but 15 seconds is not long. I would have regulated the compressed air down below 20 psi, I don't know how much you applied? You got a lot of the old fluid out! Do you think if the magnets were externally attached to the pan, that they would have trapped anything? There was a similar thread for the 6.4 and I think you came up with some genius tips here.

I have a picture posted up above with magnets on the exterior of the pan and its results.

1. You are are doing 2 fluid changes instead of 1 and re-changing new fluid.
Lets say you got an entire 8 quarts out on the first change and lets also say that you got the trans temp past 170* so that oil in the cooler is circulating through out the system because there is a thermostat.
That is 47% new and 53% old fluid.
The second fluid change you get another 8 quarts. You are now removing some of the new fluid and and have replaced 23% of the total fluid.
A total of 70% in this almost perfect situation for only dropping the pan.


In my situation I removed 13 quarts out on the first and only fluid change, that is 76%. In your situation you are
using 16 quarts worth of fluid and getting 70%.

2. Taking the time to drive 20 min.

3. Spending the fuel to drive 20 min.

If the magnet bounced off the pan then my trans would be off its mounts for that heavy of a hit.

For there to be damage by turning on the truck the trans would need to be completely dry of oil for something to happen while running the trans with the pan off for 15 seconds.

Re: How To Get More Than 8-7 Quarts

If it makes you feel better to change your fluid your way, have at it. I'm well aware that the method I described doesn't replace all of the old fluid with new fluid. I also know that when I change my oil I'm not getting all of that, either. I'd love to see what your oil change looks like.

Sometimes ya gotta ask yourself if the juice is worth the squeeze.

Good right up. I dont want to pull my pan down to see how much metal is on my magnets I put in there.
