Follow the directions In post 1 and you will have no problems. Do you have a drain plug? Are you replacing the filter?
Yes.?#1 First add 8 qts new fluid?
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.?#2 Then hook up clear line to ? so nothing clogs the new 7.3 mishimoto cooler?
It does not matter. The trans does not need to be warmed up to do this.?#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?
The only way the cooler could clog is if the transmission has already totally failed.And the fact I am hoping nothing gets clogged anywhere.
Get yourself a Scangauge II for about 150$ it will monitor trans temp and many other things and the install is plug and play.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
