Mechanical Service Repair

At Passion Auto Body & Repair, we know that keeping your car running smoothly goes far beyond its appearance. 

Mechanical issues can affect everything from safety to performance, and when something doesn’t feel right, it’s important to get it checked out before it leads to bigger—and more expensive—problems. Whether you’re dealing with engine trouble, steering issues, or transmission glitches, our shop in Franklin Park offers full mechanical repair services for drivers in and around Chicago. 

We handle routine maintenance, complex repairs, and everything in between.

From accurate diagnostics to lasting repairs, we’re here to get your vehicle back to driving at its best. 

Few things are as frustrating as engine issues

Maybe your check engine light came on, or you’ve noticed strange noises or a drop in performance. Our car engine diagnostic service gives you real answers—fast. We use professional-grade tools to pinpoint what’s wrong, whether it’s a sensor malfunction or something more serious.

If the issue needs more than a simple fix, our engine troubleshooting service can dig deeper. We check fuel systems, air intake, timing, and more to find out why your engine isn’t running as it should. Whether you need repairs, a rebuild, or even a full replacement, we’ll help you choose the right path based on your car’s condition and your budget.

As an experienced engine rebuild shop, we’ve rebuilt everything from daily drivers to performance setups. In cases where rebuilding isn’t cost-effective, we can also handle engine replacement using trusted parts and proven methods that restore reliability.

Transmission Services That Keep You Moving

If your car is hesitating between gears, slipping out of gear, or showing other signs of trouble, it’s time to check the transmission.

Delaying repairs can lead to bigger failures and more expensive service down the line. Our transmission repair service focuses on restoring smooth shifting and power delivery.

For worn or damaged units, we also restore transmissions to strong, reliable condition using quality components. If you’re just due for upkeep, our transmission fluid change service keeps things running cooler and cleaner over time—essential for avoiding early wear and tear.

We also handle issues like gear grinding or delayed engagement. If you’re dealing with inconsistent shifting or a slipping transmission repair is needed, we’ll diagnose the problem clearly and recommend a fix that lasts. 

For those driving automatics, our automatic transmission service includes diagnostic testing, fluid inspection, and adjustments as needed to keep your transmission in top shape. 

Suspension & Steering Repairs You Can Feel

Suspension problems don’t just make your ride rough—they can affect your ability to brake and steer properly. If your vehicle’s bouncing more than usual or feels unstable, you may need suspension repair. From worn-out components to bent parts, we inspect the system thoroughly to spot the issue.

A thorough car suspension service helps restore control and comfort. If your ride feels uneven or you hear clunks over bumps, it might be time for shock and strut replacement. These parts take a lot of wear over time and have a big impact on how your car handles.

When it comes to strange noises, our suspension noise repair tracks down squeaks, rattles, and clunks to find out what’s loose or worn. If your wheels feel out of sync, a suspension alignment service helps straighten things out and protect your tires from uneven wear.

For issues related to turning, we offer full steering repair services. If turning the wheel feels stiff or jumpy, our power steering repair service can check for leaks, pump issues, or pressure loss. Struggling to make turns? We address the root cause—whether it’s fluid level, pump failure, or binding in the system.

A worn or leaking steering rack can also lead to sloppy handling or fluid loss. If that’s the case, we can perform a steering rack replacement using dependable parts to restore safe, predictable control. And if your car pulls to one side, we’ll check the suspension, tires, and alignment to correct the issue and prevent further damage.

Reliable Brake Services for Safety and Control 

Brakes are your car’s most important safety feature, and any sign of trouble deserves immediate attention. If stopping takes longer than usual, or if your brake light is on, don’t wait—get it checked. 

We offer complete brake repair service for all makes and models. That includes everything from brake pad replacement to full system inspections. 

Cooling System Repairs That Prevent Bigger Problems

An overheating engine can cause major damage fast. If your temp gauge is rising or you’re losing coolant, bring your car in for a full cooling system repair. We check hoses, fans, and radiator performance to keep temperatures in check.

If you’re seeing puddles or your engine is running hot, we can track down leaks. A small leak now can lead to a blown head gasket later—so don’t wait. If needed, we also offer fast and reliable coolant leak repair, restoring the seal in your system and protecting your engine.

If you’re already dealing with high temps or warning lights, don’t risk engine damage—call us before it turns into a major engine job.

If your vehicle is running hotter than usual, it may also need water pump replacement. This crucial component moves coolant through the engine, and when it starts to fail, overheating follows. In some cases, your car may benefit from a thermostat replacement as well—restoring proper regulation so your engine doesn’t overheat or run too cold.

Mechanical issues don’t always start with big warning signs. Sometimes it’s a small sound, a change in how your car drives, or a light on the dash that you’ve been ignoring. Our team in Franklin Park is here to help you catch and fix problems early, saving you time, money, and stress. We treat every car like it’s our own—no guesswork, no rushed fixes, and no upselling. Whether it’s an engine issue, a transmission concern, or a suspension problem, we get to the root of it and handle it the right way. That’s what keeps our customers coming back—and their vehicles on the road.
