Expert Buick Verano transmission service in Chicago. Free computer diagnostic, lifetime warranty on rebuilds, all years.
2012–2017: 6-speed automatic (6T45/6T50) front-wheel drive; 2.4L naturally aspirated or 2.0T Turbo 2.0T Turbo: 6-speed automatic (6T45); higher shift pressure calibration All years: front-wheel drive only; no AWD offered
Verano 6T45/6T50 diagnosis prioritizes wave plate inspection first — fluid pan removal and metal particle inspection determines whether wave plate failure has contaminated the unit. If metal is found, full rebuild is required. Without metal, solenoid pack and valve body repair covers most shift complaints. Torque converter replacement resolves shudder that persists after fluid service. All Verano rebuilds use the updated wave plate design to prevent recurrence.
GM Dexron VI ATF, approximately 7–8 quarts; 6T45/6T50 accepts Dexron VI (unlike the larger 6L80/8L90 which require Dexron HP)
Fluid service: same day; solenoid pack: 1–2 days; wave plate rebuild: 4–6 days; full rebuild: 4–6 days
"Honest diagnosis, fair price, and the repair was done right. Chicago Transmission has been my go-to for years. Wouldn't trust anyone else with my car."
"The free diagnostic alone was worth the trip. They found the problem fast, gave me a written estimate, and completed the work on time. Exceptional service."
"Family owned and it shows. They treated my car like it was their own. The lifetime warranty on my rebuild gives me total peace of mind. Highly recommend."
Yes — the Verano shares the Delta II platform with the Chevy Cruze and uses the same 6T45/6T50 transmission. Failures and repair procedures are identical across both vehicles.
The internal aluminum wave plate in the 6T45/6T50 can fracture, sending metal shards through the transmission. It typically causes sudden complete loss of Drive. Rebuilds use an upgraded steel wave plate to prevent recurrence.
Not recommended — slipping causes heat buildup that accelerates clutch and band wear. What starts as a minor solenoid issue can become a full rebuild if driven for extended miles with slip. Get a diagnosis promptly.
Full rebuild with wave plate upgrade runs $2,400–3,600 depending on whether you have the 6T45 or 6T50. Solenoid-only repair without wave plate damage is $600–1,000.
The Verano is an underappreciated compact luxury car. If the body and engine are sound, a $2,400–3,600 rebuild is reasonable. We offer a 3-year/36,000-mile warranty on all rebuilt units.
Same-day appointments available. Honest estimates, no surprises. We've been doing this since 1987.
