Learn More →A transmission diagnostic at a dealer or independent shop typically costs $89–$150. We offer it free because we know that once you see an honest, transparent estimate from us, you'll choose Chicago Transmission.
Our computerized diagnostic reads fault codes across all transmission-related modules (TCM, PCM, ABS), logs live data from the transmission solenoids and torque converter, and gives us a starting point for a written repair estimate. You leave knowing exactly what's wrong — no obligation to continue.
Most shops use the diagnostic as a gotcha. We use it as a handshake.
Mention any offer when you call or drop in. No coupons, no print — just honest savings since 1987.
