Why Buy a Used Dodge Transmission from Auto Power Source
Dodge runs one of the most varied transmission lineups in North America. The heavy-duty side is Cummins-focused: the 68RFE 6-speed automatic and 48RE 4-speed automatic behind the 6.7L and 5.9L Cummins, plus the NV5600 and Mercedes-built G56 6-speed manuals. The HEMI-era RWD side runs the ZF-built 8HP70 8-speed (Charger, Challenger, Durango, Grand Cherokee, Ram 1500) or the older Mopar 545RFE and 42RLE. And the FWD side — Caravan, Journey, Avenger, Stratus — uses Chrysler's 41TE 4-speed and 62TE 6-speed transaxles. Matching the exact transmission code and emissions year is critical: a 68RFE from a 2010 6.7L Cummins is calibrated very differently from a 2013+ unit, and 545RFE generations differ between MDS and non-MDS HEMI applications.
Every Dodge transmission we sell has been pulled from a low-mileage donor, cataloged by VIN, and held in our climate-controlled warehouse. Each unit goes through our six-step inspection: VIN-matching against the donor and against your truck or car, ASE Shift-Testing through every forward and reverse gear under load, noise verification on the test stand, full visual inspection of the case, pan, and bell housing, multi-angle photography for your approval, and palletized freight shipping. NV5600 and G56 units get extra audible inspection for bearing whine and clutch pack wear — both are known wear items on Cummins-duty manuals. The 68RFE gets emissions-year documentation on every listing so you can confirm the 2010/2013+ split. Rejected units never reach the buyer.
You pay a fraction of dealer-new pricing for the same Mopar/ZF/Cummins-spec engineering, ship free on a heavy-duty wooden pallet anywhere in the continental U.S., and you have 30 days from delivery to return for any reason — no restocking fees, no return freight charges. The warranty printed on the listing — with extended coverage up to 3 years available — covers you if anything goes wrong after install, and our six-step inspection has held our fitment-related return rate at 0% across 100K+ shipments.

Dodge Transmission Buying Guide
5 things to verify before buying a used Dodge transmission:
-
68RFE Cummins — emissions-year matching is critical. A 68RFE pulled from a 2010 6.7L Cummins truck has different valve body programming than a 2013+ unit. Mixing them across the 2013 emissions-strategy break will throw codes and require a tune. We document donor year on every 68RFE we list.
-
2WD vs 4WD/AWD is not interchangeable. 4WD 545RFE, 68RFE, and 42RLE units carry a different rear extension housing and output shaft for the transfer case. Charger and Challenger AWD use a different ZF 8HP70 case than the RWD version. Always confirm drivetrain before ordering.
-
NV5600 6th-gear nut and input-shaft bearing wear is a known service issue. Every NV5600 we sell is stand-tested with audible inspection in all six gears under load. Any unit showing whine, bearing roughness, or a loose 6th-gear retaining nut is rejected. Ask us for the test log.
-
Fluid specs are not interchangeable across the Dodge lineup. Mopar ATF+4 fills 545RFE / 68RFE / 42RLE / 48RE; ZF Lifeguard 8 (ZF Lifeguardfluid 8) is the only fluid for the 8HP70; G56 takes Mopar synthetic manual transmission lubricant. Using the wrong fluid will void your warranty and damage clutch packs within hundreds of miles.
-
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.
