Known Chevrolet Traverse Transmission Problems

• Torque converter TCC shudder: Common on 6T75 Traverse used for family hauling with frequent stop-and-go
• 9T65 (2018+): Harsh shift complaints in early production — addressed by PCM updates but valve body wear occurs in high-mileage units

Warning Signs — When to Bring It In

• Harsh 1-2 shift
• Shudder at 35–50 mph
• Check engine P0751–P0760
• Hesitation from stop with passengers / cargo
• Hunting between gears on highway
