1994 GMC Sonoma Transmission Problems

Owner-reported complaints naming the transmission system, filed with NHTSA

Data refreshed

Transmission reportsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.
