weird kick when stopped at light 2005 taco

i have a 05 prerunner dc and notice it has a weird kick when stopped at say like stop lights.

when i make a complete stop, and my foot is on the break peddle the vehicle kinda makes a kick forward motion as if it changed gears. its nothing too dramatic but something that i was wondering if other taco owners are experiencing. if not any idea what it can be?

 

Yep, most likely its the A/C that is causing it to do that. Mine tends to behave like that when it's on.

 

You guys dont get the axel wrap too do ya Chris?

 

Sounds to me like the drive by wire system is goosing the throttle as the rpm's drop a little too low when you stop. SOP

 

It's the auto tranny, it's shifting into a lower gear, thus increasing the torque. You don't get it on a manual tranny cause you're usually stepping on the clutch when coming to a stop, or putting it in neutral.

 

I have never experienced this, oddly enough.
