Lot 306330: 2017 Chevrolet SS

The 2017 Chevy SS uses the GM 6L80 6-speed automatic transmission, and there are several common issues to be aware of:

Most Common Problems:

1. Torque Converter Issues - This is the big one! The torque converter clutch can develop shudder (feels like driving over rumble strips) between 25-55 mph. The clutch material can delaminate and damage the pump.

2. Valve Body Problems - Causes harsh shifting, delayed engagement into Drive/Reverse, and erratic gear changes due to solenoid failures.

3. TCC (Torque Converter Clutch) Performance - The converter may cycle frequently between locked and unlocked at highway speeds, causing a lurching sensation.

Typical Symptoms:

• Shuddering during acceleration
• Harsh clunking into gear
• RPM flare between shifts
• Transmission overheating
• Fault code P0741 (TCC stuck off)

Important for Your Situation: At 75,019 miles, your SS is right in the typical failure window where these problems start appearing (usually 50k-70k miles).

Repair Costs if Needed:

• Torque converter replacement: $1,200-$2,500
• Valve body replacement: $800-$1,500
• Complete rebuild: $3,000-$5,000

Prevention Tips:

• Change transmission fluid every 45k-60k miles (not the factory 100k interval)
• Use high-quality synthetic ATF
• Keep the transmission cool

The good news? Not every 6L80 fails, and proper maintenance prevents most issues. Many SS owners get well over 100k miles without major transmission problems.
