Preventive maintenance services to protect your transmission and drivetrain in Chicago's demanding climate. Chicago's stop-and-go traffic, cold starts, and road salt are harder on drivetrains than almost any other environment.
"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."
Every 30,000–40,000 miles in Chicago conditions. CVTs and ZF transmissions: every 30,000 miles. Many manufacturers say 'lifetime' — this is marketing, not engineering.
A drain-and-fill replaces the fluid in the pan (about 40–50% of total volume). A full flush circulates new fluid through the entire system including the torque converter. For most maintenance situations, a quality drain-and-fill with a new filter is appropriate.
Yes. 'Lifetime' means the factory warranty period. After that, degraded fluid is the leading cause of transmission failure. We've rebuilt transmissions with original fluid at 120k miles — not pretty.
Drain old fluid, new filter (on accessible pan units), refill with correct manufacturer-spec fluid, visual inspection of pan for metal particles, and a brief road test. Written record of fluid condition.
Absolutely — proactive maintenance is exactly what we want to see. A quick fluid inspection every 30k miles can prevent a $2,000 rebuild.
Honest estimates. No surprises. Written warranty on every job. Mon–Fri 7:30am–6pm · Sat 8am–4pm.
