Honest, Expert Transmission Repair in Elk Grove Village
That sinking feeling in your stomach when your transmission starts slipping, grinding, or jerking? We know it. A transmission problem is one of the most stressful issues you can have with your car. You’re probably worried about a massive repair bill and being without your vehicle for days.
Before you panic, come and talk to us at J&Z Garage. We’re straight shooters.
We’ve been diagnosing and repairing transmissions for over 20 years. We’ll tell you exactly what’s going on, whether it’s a simple sensor issue, a fluid problem, or something that needs a bigger repair. We’ve built our reputation on honest work, and we will never sell you a transmission rebuild if you don’t need one.
Finding the Real Problem
A lot of shops will pull a code, see a transmission fault, and immediately tell you you need a new unit. That’s the easy answer for them, but the most expensive one for you. We don’t work that way.
Our experienced mechanics use the same advanced diagnostic scanners as the dealerships, but a trouble code is just a starting point. We use our experience to find the real cause of the problem.
- Is it a failing solenoid?
- A faulty speed sensor?
- Is the fluid low, old, or burnt?
- Or is there a genuine internal mechanical failure?
We find the root of the problem and then explain your options in plain English. We believe you have the right to understand what’s wrong with your car and what it really takes to fix it.

Frequently Asked Questions (FAQs)
Not always! This is the biggest fear, but slipping is often caused by low, old, or burnt-out transmission fluid. It can also be a failing solenoid or a clogged filter. We always investigate the simple (and cheaper) solutions first.
Your owner’s manual is the best guide, but it depends on your car and how you drive. If you do a lot of towing, hauling, or heavy stop-and-go city driving, you should probably change it more often. Fresh fluid is the single best and cheapest way to make your transmission last.
Absolutely. Your car’s engine and transmission computers talk to each other. A bad transmission sensor or a shifting problem will almost always trigger the check engine light. We’ll scan the codes to see exactly which system is reporting the fault.
