"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 β ZF Lifeguard 8 fluid exchange first. If harsh shifts persist, valve body solenoid repair.
Same transmission family β ZF builds it for both. Same failure modes, same repair process.

It accelerates solenoid and TCC wear. More frequent fluid changes (every 20k miles) recommended for spirited drivers.
Absolutely β Stinger is a performance enthusiast vehicle. Rebuild with lifetime warranty makes sense.
Same-day appointments available. Honest estimates, no surprises. We've been doing this since 1987.
