Follow the directions In post 1 and you will have no problems. Do you have a drain plug? Are you replacing the filter?

?#1 First add 8 qts new fluid?
Yes.
?#2 Then hook up clear line to ? so nothing clogs the new 7.3 mishimoto cooler?
If you don't want to run the old fluid through the new cooler, don't remove line at the rear of the trans. Remove the line at the new cooler that comes from the radiator cooler to the new cooler.
?#3 We are in summer so the trans. isn't cold but it's not at operating temp because it was yesterday we did the 7.3 trans install, and today we will exchange fluid. Does that matter that it's not operating temp?
It does not matter. The trans does not need to be warmed up to do this.
And the fact I am hoping nothing gets clogged anywhere.
The only way the cooler could clog is if the transmission has already totally failed.

Yes have a drain plug... already drained...we are replacing filter... hopefully transmission isn't on it's way out...trans would get hot going up mountain with a large travel trailer...
We get a lot of information from this site to make sure we are doing things right...

Mark, do you suggest just doing the exchange through the line on the back of transmission like the normal process then...It seems like it would be easier...🤔 This 2003 Excursion has 260,000 miles on it. I love my truckn, but it has started showing the age a bit. Everyone wish us luck or a few prayers this helps resolve some of the trans cooling problems towing in mountains...
Suggestions for trans gauge? Only have the original dash gauge would like to see temps.

THANKS FOR THE HELP! I am very grateful

Get yourself a Scangauge II for about 150$ it will monitor trans temp and many other things and the install is plug and play.

Thanks will look for it!
Cheapest source for ScanGauge-2 is Advance Auto and you save 20% by ordering online. Plus you earn $20 cash perks for future purchase.

It is plug & play but you need to allow about 30 minutes to program in the various PIDs you wish to monitor.

Best money I ever spent.

Hi All,
I'm new to the ford world as I have owned rams for the last 14 years. I find myself a proud owner of a 2001 ford F-350 dually with a 7.3. I have a few questions.
1. when I drive it , shift points seem rough like they are slamming home. Is this normal? Truck has 156,000 miles on it.
It is a 4x4, in really nice condition, just replaced the glow plug wiring harness. What other issues might I be looking at.
Thanks

Congrats on the low miles 7.3.
A couple things that would affect shift points:

Do you know if it has a non-factory transmission?

Do you have a chip or tuner or is it stock?

A couple things about the 7.3:

—Genuine Motorcraft Electrical parts & Sensors seem to hold up better than after-market and are worth the extra cost.

—The HEUI system seems to be tough on oil so most of us practice more frequent oil changes than the Owners Manual suggests. For example, a full synthetic 5w-40 usually has no more than a 6,000-mile OCI (oil change interval).

—The Ford FL-1995 oil filter is a well constructed filter and as good as the competition for $10 at most auto stores and WalMart.

—Many of us keep a spare CPS in the glove box with a 10-mm wrench. It isn’t so much that they are prone to failure but they are a common fail point and one that is easily replaced roadside and inexpensive to keep a spare ($40).
