My truck is at the dealer for a leaky front diff. seal and the famous 4-3 downshift hesitation. 2 days its been there and service writer calls and tells me they have to order the seal and that there is nothing wrong with the tranny that they have done everything that ford is going to pay them for........that the hessitation is probley due to my aftermarket air-raid intake. BS!!! I read a post here last Sat. with the new version update flash for the computers in the 06's to be updated to to correct this problem. I cant find the post now so if anyone knows what that reflach version # is please help me out....Id love to make this guy eat it! I have been searching for a couple hours and still cant find the thing......should have bookmarked it before.
Thanks, Gordon

 

I had issues like that with my 05 and was never able to get the dealer to fix it.I got a xcal 1 and the new flashes it came with solved just about every issue I had.

 

Hi Gordon - you need to go to Search school

This what you're looking for?

FWIW, my calibration does not have this issue, but it's soon to be replaced anyway with my custom tunes - due to arrive this week!
