Browse 2012 Ram Transmissions by Model
Pick your 2012 Ram model to see exact fitments in stock. The one thing that catches people out this year is on the Truck 3500 Series, where Pickups are cataloged by gearbox code and Chassis Cabs by displacement — two halves of the same line described on different axes. Text us your VIN and a specialist confirms the match.
2012 Truck 3500 Series
8 units, and the line that carries this year's real trap. The 3500 is cataloged two different ways depending on body style: the Chassis Cabs are listed by displacement — 5.7L and 6.7L, each in 4X2 and 4X4, four units in all — while the two Pickups are listed by gearbox code instead, both 68RFE, one 4X2 and one 4X4, with no displacement named at all. That means a 3500 Pickup and a 3500 Chassis Cab cannot be compared on the same axis. Two more 3500s are manuals: MT 4X2 and MT 4X4, both 6.7L.
2012 Truck 2500 Series
6 units, split cleanly down the middle by fuel. The 5.7L is stocked as a plain AT in 4X2 and 4X4 with no gearbox code named; the 6.7L names the 68RFE explicitly, again in both drivetrains. The last two are manuals — MT 4X2 and MT 4X4, both 6.7L. If your 2500 is a 5.7L, drivetrain is the only question you need to answer; if it is a 6.7L, confirm the code.
2012 Truck 1500 Series
5 units, every one an automatic, and the widest engine spread of the 2012 stock: 3.7L, 4.7L and 5.7L. Note where the V6 lands — the 3.7L is stocked in 4X2 only, while the 4.7L and the 5.7L are each held in both 4X2 and 4X4. That makes the 1500 the most straightforward order on this page: name your displacement, name your drivetrain, and the unit is decided. No listing in this line names a gearbox code, and none needs to.
Why Buy a 2012 Ram Transmission from Auto Power Source
Every 2012 Ram transmission on this page was recovered from a low-mileage donor truck, cataloged against its donor VIN, and held in our climate-controlled warehouse pending sale. Nothing ships until it has cleared our six-step inspection — VIN-matching, shift testing, a road-and-shift-quality check, full visual inspection, multi-angle photography, and palletized freight.
Our ASE-certified technicians shift-test every gear and confirm clean engagement under load before a 2012 Ram transmission is cleared for sale. You pay a fraction of dealer-new pricing for the same Ram engineering, ship free on a heavy-duty pallet anywhere in the continental U.S., and get up to a 3-year warranty plus 30-day money-back. What 2012 asks of you is a careful read of the listing rather than a hunt for a code: the 1500 is settled by displacement and drivetrain, the 2500 by fuel, and the 3500 splits Pickup from Chassis Cab in a way the listings do not make obvious. Text your VIN and we will confirm.

2012 Ram Transmission Buying Guide
-
On a 3500, settle the body style before anything else. This is the 2012 mistake. Our four 3500 Chassis Cabs name their displacement (5.7L or 6.7L, 4X2 or 4X4) and never name a gearbox code; our two 3500 Pickups name the 68RFE code and never name a displacement. The two halves of the line are described on different axes, so a Pickup listing and a Chassis Cab listing will never look comparable no matter how long you stare at them. Read the body style off the door-jamb sticker first — a Chassis Cab wearing a service body still catalogs as a Chassis Cab — and the rest of the order falls into place.
-
68RFE is the only gearbox code named anywhere in the 2012 listings. Four of the nineteen units name a code — both 3500 Pickups, and the 2500 in 6.7L 4X2 and 4X4 — and all four say 68RFE. Every other listing in the year is described by displacement and drivetrain instead, with no code given. The practical consequence: the gearbox code is not the variable that decides a 2012 order. Where a listing does name the 68RFE, read it as confirmation rather than as a choice you have to make.
-
On a 1500, displacement and drivetrain are the whole conversation. The 1500 line is the easiest order on this page: pick 3.7L, 4.7L or 5.7L, then pick 4X2 or 4X4, and you are done. One catch — the 3.7L V6 is stocked in 4X2 only. So if you have a 4X4 1500, your unit is a 4.7L or a 5.7L, and there is nothing further to narrow: no 1500 listing in this year carries a gear count or a gearbox code.
-
Check whether yours is a manual — 2012 has four of them. Most of the 2012 stock is automatic, but not all of it: 15 automatics and 4 manuals. The 3500 is stocked as MT 4X2 and MT 4X4, and the 2500 matches it with an MT 4X2 and an MT 4X4 — all four on the 6.7L. Manual units share nothing with their AT siblings, so confirm the pedal count before you compare prices.
-
Watch the 68RFE spelling across listings. The same gearbox is written two ways in the 2012 catalog: the 4X4 3500 Pickup reads (68RFE) while its 4X2 twin reads (Model 68RFE). It is one transmission family and one code — the extra word carries no meaning. Do not read it as two different parts, and do not rule out a listing because the notation does not match what you searched for.
Our ASE-certified technicians verify every one of these points against your VIN before any transmission ships.

Frequently Asked Questions
What is the warranty on a 2012 Ram transmission?
Up to 3 years, depending on the specific unit. The exact warranty term is listed on each product page.
What does shift-tested mean?
ASE-certified technicians run the unit through every gear and verify clean engagement and shift quality under load before the transmission is cleared for sale.
How long until delivery?
Prep and ship time is 3-5 business days. Transit time is 2-3 business days via freight carrier after dispatch.
Can I see photos before I buy?
Yes. Multi-angle photos of the actual unit are sent before payment.
Do I need my VIN?
Yes. 2012 has one question you cannot answer by looking at the truck: on the Truck 3500 Series, our Pickups are cataloged by gearbox code and our Chassis Cabs by displacement, so the two halves of the line do not describe themselves the same way. Your VIN tells us the body style, the displacement and the code all at once, and settles the order in one step.
What if I do not approve the photos?
Every dollar back — no restocking fees, no return freight charges.
Why is this cheaper than the dealer?
It is the same Ram-engineered OEM unit, recovered from a low-mileage donor vehicle rather than built new. You skip the new-part markup and still get VIN-matching, shift testing and up to a 3-year warranty.
When can I reach your team?
24 hours a day, Monday through Saturday, at 1-877-313-8995 — or text your VIN any time and we will reply with options.

3. Shift & Road VerificationUnits are run to confirm smooth up- and down-shifts, correct torque-converter lockup and no slip — catches wear static tests miss.
4. Visual InspectionEvery accessible component is inspected: bellhousing, valve body, pan and seals, tailshaft, cooler line ports and sensor harnesses.
5. Photograph & CatalogMulti-angle photos sent to you BEFORE we ship, for your approval.
6. Palletize & ShipStrapped on a heavy-duty wooden pallet, shipped via freight at no charge.
