About and method

Why range instead of stars

Because a star rating answers a question nobody is asking. Nobody arrives with “a transmission problem”. They arrive with a CVT that shudders, a clutch that slips, or an electrical fault two shops have already failed to find — and a shop can be genuinely excellent at one of those and a complete stranger to the next.

A 4.9 earned almost entirely on fluid services and brake jobs tells you the counter staff are pleasant. It tells you nothing about whether anyone there has opened a transfer case. That gap is invisible on every other guide to these shops, because they all rank on the same number.

The rating is still here, and sorting by it is one click away. It is simply not the first thing we show you, because it is not the first thing you need.

How range is counted

Twelve kinds of work, one word list each, run over every shop's reviews by the same code. A shop covers a category when at least three separate customers describe it doing that work. One mention is not enough — it could be a quote, a diagnosis, or a referral somewhere else.

The obvious objection is that this just measures review volume, and it does not. The shop with the most reviews in San Diego covers four of the twelve. Another with 261 reviews covers five. A shop cannot buy range by collecting more reviews of the same job, which is precisely what makes it worth publishing.

An empty cell is a gap in the evidence, not a verdict. It means we have not seen that work described, not that the shop cannot do it. Plenty of good work never gets written about, and a shop that is rarely reviewed will look narrower than it really is. The honest use of this table is to shorten your shortlist and then ask.

Where the warranty figures came from

Three ways, and they are not equally strong. Some were confirmed with the shop directly. Some come from an owner's own written reply to a review, stating their standard warranty. The rest come from what customers describe in their own reviews, taking each shop's longest stated coverage so that every shop is quoted at its best.

That last method has a known bias and it is worth stating: taking the highest figure in a shop's reviews tends to pick up an outlier or a misremembered number. Every shop called so far has turned out to offer less than its reviews suggested, not more. Where a figure has been confirmed since, the confirmed one is what appears.

A blank means nobody has established the terms. It never means the shop offers no warranty, and a shop with a blank is never sorted as though it offered nothing.

What a warranty does not tell you

• It is not proof of good work. A careful shop can keep its terms modest on purpose, and a long warranty on a cheap job is still a cheap job.
• The length is only half of it. Parts-only coverage on a transmission leaves you paying the larger half of the bill, and a term honored only at that one location is worth less on a road trip than one honored nationwide. Ask.
• Whether the shop builds in house decides who is actually on the hook. A shop fitting a unit built elsewhere is usually passing through its supplier's coverage, which makes you a third party to any claim.
• Terms change, and promotions come and go. Confirm with the shop before relying on anything here.

The reviews

Every rating and review count is the figure Yelppublishes on that shop's own page. We read all 3500+ of them across 30+ shops and reconciled our totals against what the platform states. A shop needs at least 25 before we break down what its customers praise or complain about — below that a percentage describes almost nothing, and one shop here holds a perfect 5.0 from a single review.

Where our own shop lands

Miramar Transmission sits at number 1 of 17 on range, and the people who run Miramar Transmission chose to compare shops on range. Both of those are true and you should weigh them together.

What keeps that from being worthless is that the choice is stated rather than hidden, every mark in the table traces back to reviews you can go and read, and every other ordering is one click away on the browse list — including highest rated and fewest complaints, neither of which puts us first.

Corrections

If a warranty here is wrong, tell us, and tell your own customers too — a shop listed short is losing work over it. We would rather fix a number than defend it.
