What the data shows
- Median across all 2018 Civic transmissions: $799 (357 priced listings)
- Cheapest variant, a 1.5L CVT: $499 median
- Most expensive, the Type R six-speed manual: $2,500 median
- Grade A vs Grade B differs by roughly $105; trim differs by $2,000
- Twelve distinct interchange variants exist for a single model year
We pulled every listing Car-Part.com returned for the 2018 Honda Civic transmission: 527 listings across twelve interchange variants, 357 of them with a posted price rather than a "call for quote." Here's what the spread actually looks like.
A 5x Spread Inside One Model Year
One model year. One part name. Twelve different parts.
| Variant | Priced listings | Median |
|---|---|---|
| CVT, 1.5L (ID 200315CKA10) | 42 | $499 |
| CVT, 1.5L (ID 2002D5CGC400) | 36 | $676 |
| MT, 1.5L, Sedan, EX | 23 | $700 |
| CVT, 1.5L (ID 200315CK010) | 38 | $750 |
| MT, 2.0L, naturally aspirated | 13 | $849 |
| MT, 1.5L, Hatchback | 23 | $895 |
| CVT, 2.0L | 22 | $899 |
| MT, 1.5L, Sedan, Si | 42 | $1,748 |
| MT, 2.0L, turbo (Type R) | 17 | $2,500 |
Why Trim Decides the Price
Two forces are at work, and they point the same direction.
Production volume. Honda sold base and EX Civics by the hundreds of thousands. Si and Type R production is a fraction of that. Fewer cars built means fewer cars scrapped, which means fewer transmissions on yard shelves. Our index found 42 listings for the most common CVT and 17 for the Type R, and that's after searching nationally. Buyer urgency. A Type R owner with a failed gearbox has almost nowhere else to go. The remanufactured market for low-volume performance drivetrains is thin, and a new unit from Honda is priced accordingly. Yards know this.Note what *isn't* driving the gap: the manual gearbox in a Type R is not five times more complex than a CVT. You're paying for scarcity.
Grade Moves Price Less Than Trim Does
Salvage yards assign condition grades: A for the best units, B for mid, C for lower, X when they haven't graded it. Buyers tend to fixate on this letter. The data suggests they're watching the wrong variable.
| Grade | Priced listings | Median |
|---|---|---|
| A | 229 | $800 |
| X (ungraded) | 58 | $850 |
| B | 69 | $695 |
| C | 1 | $249 |
The ungraded listings sitting *above* Grade A in that table is worth a glance too. Ungraded doesn't mean poor. It usually means a smaller yard that doesn't run a formal grading program, and those units skew toward the expensive variants in our sample.
How we got these numbers
Every listing came from Car-Part.com's national index, captured for the 2018 model year across all twelve interchange variants Honda publishes. We record the posted price, condition grade, mileage, and yard location for each. Listings marked "call for quote" are counted in the listing total but excluded from price medians, which is why 527 listings produce 357 priced data points. Medians, not averages, are used throughout. A single $3,810 outlier shouldn't set your expectations.
What This Means When You're Buying
Find your interchange variant before you shop. Your VIN's 6th digit distinguishes the 2.0L from the 1.5L on a 2018 Civic. Body style and trim badge narrow it the rest of the way. Getting this wrong means a part that physically bolts in but doesn't work with your ECU. Treat the median as your anchor, not the minimum. The cheapest listing in a variant is usually the highest-mileage or ungraded unit. If your variant's median is $700, a $400 listing is telling you something about that specific part. Widen the search radius on rare variants. With only 17 Type R transmissions listed nationally, a 100-mile search will likely return nothing. Shipping a transmission costs real money, but it costs less than the gap between an available part and no part.Prices in this analysis reflect what yards were asking at capture time. They move.
