Modern luxury vehicles rely on advanced multi-speed automatic, dual-clutch (DCT), or continuously variable transmissions (CVT) to manage gear changes smoothly. These complex systems use specialized hydraulic pressures to keep performance crisp and seamless. Over time, high operating temperatures break down the fluid's protective properties, which can cause erratic shifting patterns, gear slipping, or expensive mechanical failures if left unserviced.

The specialized service center at Autos of Chicago, located at 1555 East Rand Road in Arlington Heights, provides precise transmission system fluid exchanges. Our factory-trained technicians use advanced diagnostic equipment to service your vehicle's transmission safely and accurately.

Our Complete Transmission System Service Checklist

We keep your luxury gearbox performing reliably by following a meticulous inspection and maintenance process:

Step 1: Onboard Diagnostic Scanning and Temperature Review
We plug into your vehicle's computer networks to check for transmission fault codes and monitor real-time oil temperatures to ensure safe, accurate fluid management.
Step 2: Low-Pressure Fluid Extraction and Controlled Drain
Our team avoids high-pressure flushes that can damage sensitive internal valves. Instead, we use a gentle, low-pressure extraction process to drain the old oil safely.
Step 3: New Sump Pan Gasket and Internal Fluid Filter Installation
We remove the transmission pan to clean out trapped debris, replace the internal fluid filter, and install a fresh factory gasket to prevent leaks.
Step 4: Factory Fluid Refill and Electronic Level Calibration
We refill the system with premium, vehicle-specific synthetic fluid and perform an electronic level check to ensure smooth gear changes.
