Why Buy a Used Scion Transmission from Auto Power Source
Scion ran fewer models than any other Toyota brand and still managed to change the gearbox behind the same badge more than once — a tC automatic is a four-speed through 2010 and a six-speed from 2011, a tC manual is a five-speed or a six-speed on the same split, an xB is a 1.5L unit through 2006 and a 2.4L unit from 2008, and the FR-S, iQ, iM and iA carry units built by Subaru, Aisin and Mazda that share nothing with the rest of the line. Every product on this page is titled by model, by AT or MT, and by (CVT) or (6 speed) where the unit is neither a conventional automatic nor a manual, so the year and model on the listing settle the exact transaxle. Our 63 verified Scion transmissions cover the whole run: the tC six-speed and four-speed automatics and manuals, the xB and xD four-speed automatics, the xB five-speed manual, the xA and first-generation xB units, the FR-S six-speeds, the iQ and iM CVTs, and the iA six-speed automatic.
Every Scion transmission we sell has been pulled from a low-mileage donor vehicle, cataloged by VIN, and held in our climate-controlled warehouse pending sale. Each unit goes through our six-step inspection — VIN-matching against the donor and against your vehicle, Shift-Testing through every gear under load, noise verification, full visual inspection of case, pan and bellhousing, multi-angle photography for your approval, and palletized freight. Automatic transaxles get a valve-body and solenoid check under load, CVT units get a belt, pulley and fluid-condition inspection, manual transaxles get a synchro and clutch-face check, and the FR-S rear-drive units get an output-shaft and seal inspection. Rejected units never reach the buyer.
You pay a fraction of dealer-new pricing for the same Toyota engineering, ship free on a heavy-duty pallet anywhere in the continental U.S., and have 30 days from delivery to return for any reason — no restocking fees. The warranty printed on the listing — with extended coverage up to 3 years available — covers you if anything goes wrong after install. Across 100K+ engines and transmissions in stock, we hold a 0% fitment-related return rate.

Scion Transmission Buying Guide
5 things to verify before buying a used Scion transmission:
-
Match the model and the year first — the same badge carries two different units. A tC automatic is a four-speed through 2010 and a six-speed from 2011; a tC manual is a five-speed through 2010 and a six-speed from 2011; an xB is a 1.5L four-speed or five-speed through 2006 and a 2.4L unit from 2008. None of these pairs interchange across the split — the year on the listing is the first thing to check.
-
AT and MT units are listed separately on every model. Every Scion listing says AT or MT. The automatic and manual transaxles behind the same engine carry different bellhousings, mounts and controllers — match the listing to the transmission your car left the factory with.
-
(CVT) and (6 speed) mark the units that are neither a conventional automatic nor a manual. The iQ and iM are listed AT, (CVT) because they carry continuously variable transaxles, and the iA is listed AT, (6 speed) because it carries a Mazda-built six-speed. A conventional four-speed or six-speed automatic from a tC or xB will not fit any of them.
-
The FR-S is rear-wheel drive and shares nothing with the other Scions. The FR-S six-speed automatic and manual are longitudinal rear-drive units shared with the Subaru BRZ and Toyota 86. Every other transaxle on this page is a front-drive unit — an FR-S listing is the only one that fits an FR-S.
-
Confirm the match with your own VIN before you order. Your VIN settles the transmission code, drivetrain and build split in one step. Text it to +1-307-441-5554 and we will confirm in writing exactly which unit fits your vehicle before you pay.
Our ASE-certified technicians verify every one of these points against your VIN before any unit ships.
