    I searched the site but didn't find an answer to this.

    The cruise control on my 98 taco 2.7L auto 4x4 is so sensitive it is useless. Set it to cruise at 60 or so, and at the slightest incline or resistance it downshifts, but once over the incline, and going downhill, it won't upshift. Take it out of cruise and it quickly upshifts back to overdrive.

    With cruise off, it never downshifts on slight inclines and it's easy to keep in overdrive. Actually, it takes a serious press on the pedal to get it to downshift.

    Can't find any info on adjusting the thing.

    Anyone else have this problem? Fixes?

    Go to your nearest incline & before you start up it set your cruise for the speed limit or whatever (60mph I think you said) & make a note at what SPEED your dash tells you i.e; If you set it for 60mph if its working right you'll maintain that speed whether going up hill or down, don't try to think for the tranny its responding to the many adjustments that the on board CPU is pulsing to your CC & back to the transmission.......:cool:

    It definitely holds the speed at which it is set. The problem is it won't stay in overdrive. It downshifts to overdrive at the slightest resistance, then won't go back into overdrive after the resistance.

    I'd like to adjust it so it is not so sensitive- okay if it slows just a bit below the set level without downshifting. But if it has to downshift, it should at least upshift after the incline/resistance.

    Shifting out of overdrive when 'resistance' (decreased speed) occurs is normal behavior - it's the way the cruise control system is designed. It cuts out whenever vehicle speed drops 2.5 mph below the speed you set.
