| QUICK ANSWER
Some Denver transmission shops offer free diagnostics, but the term varies widely – for some it means a quick code scan, for others a full inspection. Advanced Transmission Center’s free TrueTest™ diagnosis includes a fluid check, computer scan, road test, and physical inspection, with a digital vehicle inspection (DVI) provided before any repair is quoted. Why us: A free diagnosis is only valuable if it’s thorough. Ask any shop what their ‘free check’ actually includes. |
Three questions that reveal what a ‘free check’ really is
- Does it include a road test? Code scans without a road test miss how the transmission behaves under load.
- Do I get the findings in writing? Verbal-only findings make second opinions impossible.
- Is the diagnosis free even if I don’t repair with you? If it’s only free with a repair, it isn’t free.
What to bring and what happens
Bring the vehicle (or call for towing if it can’t drive), any codes you’ve already pulled, and a description of when the symptom happens – cold mornings, highway speed, under load. You’ll leave with a clear answer: what’s wrong, what it costs to fix, and whether it’s worth fixing on your vehicle’s mileage. Sometimes the honest answer is ‘don’t fix it’ – and a good shop will say so.
Frequently Asked Questions
Why do some shops charge $100–$200 for a diagnosis?
Diagnostic time has real cost, so charging isn’t a scam by itself. But shops that charge often credit it toward repair — which subtly pressures you to repair there. A genuinely free diagnosis keeps your options open.
Can I get a free diagnosis for a second opinion?
Yes – second opinions are one of the most common uses of our free TrueTest™ inspection, and we encourage them. Bring the other shop’s estimate if you have it.
