Hello everybody, I have a 2007 f150 fx4 CC with the 5.4.and 3.73 gears and 285 tires and EDGE Evolution. I was towing my friends four-door jeep yesterday and I noticed some odd shifting. I turned off overdrive and the torque converter would lock in third gear. As I started up a hill in 3rd gear with the T/C locked it started lugging and then downshifted to second and the torque converter stayed locked. The only way it would unlock is if I let off the gas. Is this normal?

Thanks, Jack

 

Anyone?

 

Has that happened before?

 

Yes happens every time I downshift with torque converter locked in third gear.

 

Have you tried returning to the stock tune? Your Edge may be fubar.

 

i'd say normal. Keeps the trans cooler.

 

It's not normal if it's to that extreme.
