✓ Free diagnostic

Free diagnostic. Honest answer. You pay when I start ordering parts.

I scan it, I drive it, I tell you what I'd do next. Not what makes me the most money.

Before you spend a penny on parts, find out what's actually wrong. Drop it off, I tear it down and tell you what I find. No charge. You pay when I start ordering parts.

Fig. 25 · How I diagnose

Four steps. Plain-English answer at the end.

If my daughter drove this in, I'd tell her exactly what I'm telling you. Here's what the free diagnostic actually covers.

The drive test catches what the scanner misses. Varnished fluid and metal on the dipstick [FIG. 01] tell you more in 30 seconds than an hour on the scan tool.

I. Scan, fluid, drive

I drive it the way you do.

Full OBD-II scan, plus the manufacturer codes. I pull the dipstick: color, smell, level, metal. Then the keys go in my pocket and I run your loop: uphill, merging, stop-and-go, and highway speed with the TCC locked. Codes are a starting point. The drive tells you which part.

Pre-scan + fluid check + drive test: about 60 minutes, same day.

II. Honest call

Plain-English answer before close.

A phone call (or text with photos) telling you what it is, what it will cost, and whether I would even touch it.

III. No charge to look

Free teardown + written quote.

You pay when I start ordering parts, not before. If you take the write-up elsewhere, you still walk out with a plain-English report.

What I'd tell my own daughter

If my daughter drove this in, I'd tell her to fix the solenoid and drive it another 40,000 miles. Same advice I'm giving you.

Very please with the company. I dropped my van off on a Saturday and it was completely rebuilt by Tuesday. It has been done a few weeks now and I have not had any issues. Highly recommend

Diagnostic questions I get

Before you call.

What does a diagnostic cost?

Nothing. Drop it off, I scan it, I drive it, I pull the pan if it needs it. No charge. You pay when I start ordering parts for the repair. If you take the write-up elsewhere, you still walk out with a plain-English report.

Will the check engine light tell you what's wrong?

Codes are a starting point, not an answer. A P0700 means 'look at the transmission,' and it doesn't tell you WHICH part. That's what the fluid check and drive test are for.

How long does a diagnostic take?

Usually same-day if you drop it by 9am. I call you with the answer before close.
