""why did you use the 1 and 2 gear instead of 3 with od off?""
I think he said he was hunting. I also "think" hunting is illegal on asphalt. (BG)
"oh, and Ford scolded me for using 1st and 2nd to "brake" going downhill."
That burns me up!! Just like those (^$@#*&) warranty companies that void the warranty because you have one size larger tire on your truck!!
As a professional transmission tech, I can tell you that did NOT damage your trans in ANY way.
No thermal bypass needed but, if you have a cooler in the rad and an air cooler, do not add a 3rd cooler unless you bypass the rad cooler.
A bad day of hunting is better than a good day at work!!
