2015 Used Ram Transmissions For Sale
39 verified 2015 Ram transmissions are on the shelf — 36 automatics and 3 manuals. Nearly half of them are Truck 3500 Series units, which makes this the deepest heavy-duty year in our Ram stock and also the fussiest to order, because Ram built the same 3500 with a gearbox from either Aisin Seiki or Chrysler; alongside those sit 10 Truck 1500 Series units, 7 in the 2500 Series, 2 full-size Promaster vans and a single Promaster City. Every one is VIN-matched to your vehicle, shift-tested by ASE-certified technicians, photographed before shipment, and backed by up to a 3-year warranty plus 30-day money-back. Free freight nationwide.

Browse 2015 Ram Transmissions by Model
Pick your 2015 Ram model to see exact fitments in stock. Two things separate 2015 listings that otherwise read identically: on the 4X2 3.6L 1500, the axle ratio the truck was built with, and on the heavy-duty 3500, which company built the gearbox. Neither is visible from the outside of the truck. Text us your VIN and a specialist confirms the match.
2015 Truck 3500 Series
19 units — the deepest 2015 line by a wide margin, and the one that rewards a careful order. The same 3500 was cataloged with a gearbox built by either Aisin Seiki (AS69RC behind the 6.7L, AS66RC behind the 6.4L Chassis Cab) or Chrysler (68RFE on the 6.7L, 66RFE on the 6.4L). Pickup and Chassis Cab are cataloged apart, each in 4X2 and 4X4; the 6.4L AS66RC Chassis Cabs split again into PTO (Left Side) and W/O PTO; and 2015 is the year the 3500 is stocked as a manual in both drivetrains — MT 4X2 and MT 4X4, both 6.7L.
2015 Truck 1500 Series
10 units, every one an automatic. 3.6L, 5.7L and 3.0L (Diesel), in 4X2 and 4X4. The 2015 trap lives here: the 4X2 3.6L is cataloged three separate times and the only thing telling those listings apart is the AXLE RATIO — 3.21, 3.55 or 3.92. Not displacement, not drivetrain. The 5.7L is separately built as a 6 Speed and an 8 Speed, so a 5.7L 4X4 is still two different transmissions until you count the gears.
2015 Truck 2500 Series
7 units. The automatics name their gearbox code in the listing — 68RFE behind the 6.7L diesel, 66RFE behind the 5.7L and 6.4L gas — in 4X2 and 4X4. One unit is a manual: MT 4X4 (6.7L, Diesel, VIN L, 8th Digit). Confirm fuel type and drivetrain on the door-jamb sticker and the code follows from it.
2015 Promaster
2 full-size van units, both automatic and both straightforward — Promaster 1500 and Promaster 2500 on the 3.6L Gasoline Engine, running a single specification through the year with no build-date break to work around.
2015 Promaster City
A single Promaster City unit: AT (9 Speed), 2.4L, FWD. The City is a separate, smaller vehicle rather than a short Promaster and shares no transmission with the full-size vans — if your badge says City, this one listing is the whole of our 2015 stock for it.
Why Buy a 2015 Ram Transmission from Auto Power Source
Every 2015 Ram transmission on this page was recovered from a low-mileage donor truck or van, 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 2015 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 makes 2015 worth slowing down for is that its hardest questions are invisible ones — which of three axle ratios sits under your 4X2 3.6L, which company built your 3500 gearbox, and whether you are one of the three manual owners in this collection. Text your VIN and we will confirm.

2015 Ram Transmission Buying Guide
-
On a 4X2 3.6L 1500, find your axle ratio. This is the 2015 mistake. The 4X2 3.6L Truck 1500 Series is cataloged three times for this year — 3.21, 3.55 and 3.92 Axle Ratio — and the axle ratio is the only thing separating those three listings. Same year, same displacement, same drivetrain. It is not printed on the outside of the truck; it is on the build sticker and it follows from the VIN. Order on displacement alone here and you have a one-in-three chance of being right.
-
On a 3500, find out who built your gearbox. Ram cataloged the same 2015 3500 with either an Aisin Seiki unit — AS69RC behind the 6.7L, AS66RC behind the 6.4L Chassis Cab — or a Chrysler-built one, 68RFE on the 6.7L and 66RFE on the 6.4L. Our 2015 stock holds the 6.7L Pickup in both makes and the 6.4L Chassis Cab in both makes: same year, same fuel, same drivetrain, different transmission. Nothing on the outside of the truck announces which one you have.
-
Check whether yours is a manual — 2015 has three of them. Most of our 2015 stock is automatic, but not all of it. The 3500 is stocked as a manual in both drivetrains this year, MT 4X2 and MT 4X4 (both 6.7L), and the 2500 adds an MT 4X4 (6.7L, Diesel, VIN L, 8th Digit). Manual units share nothing with their AT siblings. On a diesel 2500 the 8th VIN digit identifies the engine the manual was paired to — read it before you order.
-
On a 5.7L 1500, count the gears. The 2015 5.7L Truck 1500 Series was built as a 6 Speed and as an 8 Speed, in both 4X2 and 4X4, and our listings separate those by gear count and nothing else. Displacement alone will never narrow the order down.
-
Separate Pickup from Chassis Cab, and check for PTO. On the 3500 the Pickup and the Chassis Cab are cataloged apart, and the 6.4L Aisin Seiki AS66RC Chassis Cabs are built either with PTO (Left Side) or W/O PTO. PTO housings are not interchangeable — a PTO case will not bolt into a truck that never had one, and a plain case cannot be adapted to drive one.
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 2015 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. Three 2015 questions cannot be answered by looking at the truck: which axle ratio your 4X2 3.6L 1500 was built with, whether your 3500 gearbox came from Aisin Seiki or Chrysler, and — on the 5.7L 1500 — whether you have the 6 Speed or the 8 Speed. Your VIN settles all three.
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.

Our 6-Step Inspection & Shipping Process
Every 2015 Ram transmission we ship has been through these six steps:
1. VIN-MatchingWe match the donor VIN to your VIN to confirm the body style, displacement, axle ratio, gearbox manufacturer and drivetrain — the five things that decide a 2015 Ram fit.
2. Tested & VerifiedASE-certified technicians shift-test the unit through every gear and verify clean engagement under load.
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, PTO housing where fitted, 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.
