When driving in snow or slush above 45 mph, I feel a quick jerk or hesitation on an intermittent basis. After a couple of times the wrench light for the drive-train comes on and I loose engine performance. Only happens in snow, not rain or dry pavement regardless of the temperature outside. Shut the engine off and restart and the light is out and drives okay until the next jerking episode.

Good evening.

This sounds like your stability track system was activated. If you had wheel slipping, that would explain it.

Can you check for any codes?

I will head to my local AutoZone in a hour or two and have them check for codes. Will let you know.

Okay, thanks.

This looks like a communication issue with the ECM and the other modules.

It could be either a re-flash needed or the ECM itself. The fact it happens in wet weather only could be from a connection at the ECM or the throttle actuator. I would clean the connections and use dielectric grease for a better connection.
