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.

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.

Your 2012 Ram Transmission Options: Compared

Most 2012 Ram owners face four real choices when their transmission fails:

Tested used OEM hits the sweet spot — same Ram engineering as new, fraction of the cost.

2012 Ram Transmission Buying Guide

1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
