Why Buy Audi Transmissions from Auto Power Source
Audi powertrains use a wider variety of transmissions than nearly any other German marque, and the differences between transverse and longitudinal architectures matter enormously for fitment. Pre-2008 A4 and A6 longitudinal cars commonly run the ZF-supplied 5HP or 6HP Tiptronic; from 2009 forward the ZF 8HP became the dominant longitudinal automatic and now equips most A4, A5, A6, A7, A8, Q5 and Q7 models built after 2010. On the transverse side, A3, TT and Q3 rely on the 6-speed DSG (DQ250) and later the 7-speed S-tronic (DQ200) dual-clutch units — both completely incompatible with the longitudinal cars despite sharing branding. FWD A4 and A6 owners are the third bucket: many of those cars left the factory with the Multitronic chain-CVT, which is unique to Audi and only available on front-wheel-drive variants.
Our 710+ Audi transmissions have each been pulled from low-mileage donor vehicles, cataloged by VIN, and held in our climate-controlled warehouse pending sale. Every unit goes through our six-step inspection: VIN-matching against the donor and against your car, ASE Shift-Testing through all gears, noise & smoke verification, full visual inspection of the case, valve body and pan, multi-angle photography for your approval, and palletized freight shipping. The ASE-certified techs do the testing — rejected units never reach the buyer.
You pay a fraction of dealer-new pricing for the same Audi engineering, ship free on a heavy-duty pallet anywhere in the continental U.S., and you have 30 days from delivery to return for any reason — no restocking fees. Up to a 3-year warranty covers you if anything goes wrong after install, and our six-step inspection has held our fitment-related return rate at 0% across 46,000+ shipments.

Audi Transmission Buying Guide
Audi transmissions look very similar across model years because most share Audi part-number prefixes (0B, 0BK, 0BL, 0AW, 0CK, 0BH, 0CN), but the internal hardware varies year-to-year and a wrong long-block on the buyer side is the single most common source of failed Audi swaps. Five checks before you order:
-
Match the transmission code on the donor by VIN. Decode your VIN to confirm 3-letter transmission code (e.g. NXX, JFB, KKU, KGS). Sellers who can't share the donor VIN should be avoided.
-
Confirm transverse vs longitudinal. A3, TT and Q3 use transverse transmissions; A4, A5, A6, A7, A8, Q5, Q7 use longitudinal. Bell housings and torque inputs are different — they will not interchange.
-
For Quattro vehicles, verify AWD output flange. Tiptronic 6-speed and ZF 8HP variants come in both 2WD and Quattro forms; the rear output is the dividing feature.
-
Multitronic is FWD-only. Never accept a Multitronic for a Quattro car — it physically cannot drive the rear axle.
-
S-tronic DCT vs Tiptronic torque-converter — confirm which one you have. A B8 A4 with the 7-speed S-tronic shares almost nothing internally with the 6-speed Tiptronic A4 of the same year. Cosmetic similarity is misleading.
Our ASE-certified technicians verify every one of these points against your VIN before any transmission ships.
