Truck downshifts when turn signal is used

[joseyaaron]

Cruising at highway speeds, when using the turn signal to change lanes, the truck will down shift. Also the crusie control does not work. 96 f350 crew cab powerstroke diesel 4x4.

Actually its the TC unlocking. Look at your clock spring.

What Chuck said. Also make sure all of your bulbs are good. As weird as it sounds they have been known to have that problem when a bulb is out.

How exactly do you "check" or test a clockspring?
Thanks,

Mine kicks off the cruse when I turn on the turn signal and all the bulbs are good . . . so what is the clock spring and what does it do?

You will have to open up your steering wheel, remove the screws from the back side. This is the little jewel. Pretty common for them to mess up.
