Transmission Major

Transmission rebuild or replacement, torque converter, premature clutch replacement.

What Owners Say

Transmission rebuild or replacement

"Bought car with 29000 miles in it. After driving 3000 miles dealership found shavings in the fluid and said it needed replaced. It was out of the time warranty, but within mileage warranty timeframe. Chevrolet would not cover any of the repair."

Anonymous, KY (2018 Chevrolet Suburban Premier 5.3-L V8)

""Transmission replacement was required when the torque converter experienced internal delamination & disintegration, causing contamination of the transmission fluid and complete failure of the transmission. Fortunately when I bought the vehicle (used) I'd seen on Consumer Reports that transmission problems around 100K miles were an issue and insisted on a 5-year/50K mile warranty on the powertrain, so this $8000+ repair was 100% covered.""

Anonymous, CT (2018 Chevrolet Suburban LT 5.3-L V8)

"Transmission tore itself apart around 100K miles but the damage was clearly longstanding as was likely the reason the first owner sold it."
