Clutch replacement, gearbox rebuilds, synchro replacement, and manual transmission fluid service for all makes and models. Since 1987.
"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."
Clutch issues show up as slip (RPMs rise without acceleration), chatter, or a clutch pedal that's too high/low. Gearbox issues show up as grinding when shifting, popping out of gear, or gears that won't engage. Sometimes both fail together — a free diagnostic drives, and we put it on the lift to confirm which system needs attention.
We inspect and measure the flywheel every time we do a clutch. If it's within spec, we resurface it — included in most clutch quotes. If it's cracked, hard-spotted, or below minimum thickness, we recommend replacement. A new clutch on a damaged flywheel wears out fast.
Most FWD clutch replacements are done in 1 business day. RWD vehicles take 1–2 days. Full gearbox rebuilds take 2–3 business days.
