"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."
No β harsh 1-2 shifts on the 6T30 are valve body bore wear. P0751 confirms it. Catch it early for a less expensive repair.
Different platform β Encore GX uses the 9T50 9-speed. Same GM family, different unit.
1β2 days for most repairs.
Dexron VI β change every 45,000 miles.
The 1.4T/6T30 combination is adequate for daily use. The transmission is the weakest link β fluid changes matter.
