Does CARFAX Show Transmission Replacement: Rows, Receipts, and CVTs

Yes, sometimes. Transmission replacement is one of the few repairs CARFAX names on its own sales page, so a swap done by a dealer or shop that sends records to CARFAX can show up as a dated service row. A gearbox dropped in by a cash shop, a mobile mechanic, or a guy with a junkyard unit and a floor jack usually leaves no row. So in early October 2026, a clean service history on a 120,000-mile CVT car says little about which transmission is in there now. The paperwork and a mechanic have to fill that gap.

Where a transmission swap lands on the report

When it shows, it lands in the service history beside oil changes and tire rotations. On the morning we wrote this, the CARFAX vehicle history reports page still listed Transmission Replacement under Service History, next to brake rotor replacement, open recalls, and safety inspections. That same page says the database holds billions of records from more than 151,000 sources. The job still has to happen at one of them for a row to appear.

Our guide to what service records mean on CARFAX covers the terse wording shops use, and major service events on CARFAX explains why a big repair can appear as one short line. Check the mileage around the entry, too. A long gap with no records ahead of the swap can mean the car sat broken or went through a shop that never reports. If the owner kept the invoice, they can try adding service records to CARFAX, though most sellers never bother.

Rebuilt, remanufactured, or used: the invoice has to say which

A "new transmission" on a used car is almost never brand new, and the invoice should tell you what actually went in. Kelley Blue Book's transmission repair and replacement guide says a rebuild replaces only the failed parts and can be done at a local shop, while a remanufactured unit is restored to factory standards on a factory line and costs more. KBB also says brand new transmissions are mostly reserved for new cars.

The FTC's guides for rebuilt and used auto parts name transmissions and transaxles as covered products and say it is deceptive to sell one without clearly disclosing that it is used, rebuilt, or remanufactured, including on invoices. California goes further for repair shops, and 16 CCR 3356 makes every invoice describe each part supplied and state whether it was new, used, reconditioned, or rebuilt. So an invoice that just says "trans replaced" with no part type and no warranty terms is a weak document, and we would treat it that way.

Numbers on the case can tell you it was swapped

On many cars the transmission itself carries an ID that should match the car. Under the federal theft prevention standard, 49 CFR 541.5 requires covered passenger vehicles to have an identifying number on the transmission, normally the VIN, or at least its last eight characters for makers that were already doing that in 1984. A covered replacement part is marked differently, since 49 CFR 541.6 says it must carry the parts maker's trademark or another unique identifier plus the letter "R," at least one centimeter high. So a mechanic who finds a different VIN tail, or an R mark, on the case has found a swap, whatever the report says. This only applies to vehicles and parts covered by the standard, and stamps can be hard to see without a lift, so ask the inspecting shop to look.

CVT trouble is why this question comes up so much

Transmission replacements cluster on certain models, and a lot of them are CVTs. Consumer Reports, in a member-survey roundup updated May 29, 2021, said several Nissans stood out for how often their CVT needed replacing, listed the 2013 Sentra with typical failures between 77,000 and 123,000 miles, and quoted one Murano owner who paid $5,000.

Nissan's November 2, 2023 dealer bulletin filed with NHTSA extended CVT coverage on the 2017 and 2018 Altima and the 2018 and 2019 Sentra and Versa from 60 months or 60,000 miles to 84 months or 84,000 miles, and says the extension transfers to later owners automatically. Road and Track reported in May 2025 on a similar settlement for 2015 to 2018 Murano and 2016 to 2018 Maxima owners, with reimbursement of up to $5,000 for qualifying CVT work done at an independent shop. It noted most of those cars had already passed seven years. Honestly, on these models a dealer CVT row is often a decent sign, since it can mean the unit was replaced under that coverage, so ask for the repair order to confirm who paid.

Recalls and replacements are separate records

A transmission recall on the report tells you about a fix campaign, and a big one filed this April ends in a software update. NHTSA's acknowledgment of recall 26V237, dated April 16, 2026, covers 1,392,935 Ford F-150s from 2015 to 2017 that can unexpectedly downshift into second gear, and the free remedy is a powertrain control module software update. The AP reported that Ford knew of 444 warranty claims and two injuries possibly tied to the problem.

CARFAX lists open recalls as their own item, and our posts on open recalls on CARFAX and NHTSA recall lookups versus CARFAX show how to confirm one is closed. On a truck like that, you want the recall closed and a separate answer about the gearbox.

How to check the transmission yourself

A history report is only a starting point here, and the FTC says so. Its guide to buying a used car from a dealer says a vehicle history report is no substitute for an independent inspection and typically will not list mechanical problems. Get the mechanic's findings in writing with an estimate. Book a pre-purchase inspection, ask for a code scan, a fluid check, and a road test with cold shifts and highway speed, and use our mechanic checklist so the shop sees the report too. The PPI versus CARFAX breakdown shows what each catches. If the car came from a flood area, read about transmission connector corrosion before you trust any shift quality.

Then read the window paperwork. The FTC's Used Car Rule says a dealer offering a warranty has to name the specific systems covered, such as engine, transmission, and differential, and cannot use shorthand like "powertrain." Our Buyers Guide explainer covers the boxes. The FTC also says that if you buy a dealer service contract within 90 days of the sale, the dealer cannot drop implied warranties on the systems that contract covers, even on an as-is car. Compare the terms in our guide to used car service contracts.

What a swap costs, and what the report costs

KBB puts the average for a new transmission at $2,900 to $7,100, and says make, transmission type, and rebuild versus reman all move the number. So a seller's "just put in a new trans" line deserves an invoice, a shop name, and warranty terms. A tired junkyard unit and a fresh reman can feel the same on a ten-minute test drive. Ask whether any parts warranty transfers to you.

A seller who emails a clean PDF and talks up a fresh gearbox in the same breath is a reason to pull your own copy, since seller-provided reports can be old or edited. We're a licensed CARFAX and AutoCheck reseller, not affiliated with CARFAX, AutoCheck, or Experian. Reports run about $5.50 as a guest, about $4.50 for members, and about $6.75 for the bundle, while retail usually sits around $39.99 to $44.99, so confirm the total at checkout. If the report shows a transmission row, call the shop named on it. If it shows nothing, treat the swap story as unverified until a receipt turns up, as we did with the engine replacement question.
