What's wrong, in plain English

Certain Chevrolet Silverado and GMC Sierra trucks may not have been fully fixed by an earlier recall that addressed this same transmission problem. In these trucks, the transmission control valve can fail. When that happens, the rear wheels may lock up suddenly while the truck is being driven.

What you should do

Check your VIN at nhtsa.gov/recalls to see if your truck is affected, including if it was previously repaired under recall 24V797.
Contact a GMC dealer at 1-800-462-8782 or a Chevrolet dealer at 1-800-222-1020 to schedule the inspection and software update.
The repair is free.

Where do I find my VIN, and what do I tell the dealer?

Your VIN is the 17-character code on the lower left of the windshield, on your registration and usually on your insurance card. Enter it at nhtsa.gov/recalls to see whether this recall is still open on your car. When you call the dealer, say you have an open safety recall and give them NHTSA campaign number 26V083000.
