Audi RS6 C8 transmission

Product Overview

For sale is a complete Audi RS6 / RS7 C8 automatic transmission, code TNQ, manufactured in 2021 and recording 17,546 kilometres. This is the 8-speed torque converter automatic transmission as fitted to the C8-generation Audi RS6 Avant and RS7 Sportback in their 4.0 TFSI Mild Hybrid (MHEV) specification — the 441 kW / 600 hp, Quattro all-wheel-drive application — compatible with engine code DJPB and chassis codes 4KA (RS6).

At 17,546 kilometres from a 2021 build, this transmission is at an early stage in its operational life. All internal components — torque converter, multi-plate clutch packs, valve body, Quattro output differential, and all gear sets — will be in excellent condition consistent with this conservative mileage. For any RS6 or RS7 C8 owner requiring a replacement, this is a low-mileage, correctly-specified unit at a meaningful saving to new Audi dealer supply.

Transmission Specification

About the Audi RS6 / RS7 C8 TNQ Transmission

The TNQ transmission code identifies the specific 8-speed automatic calibration fitted to the C8-generation Audi RS6 Avant and RS7 Sportback in 4.0 TFSI MHEV specification. The C8 RS6 and RS7 share the same platform, drivetrain, and engine — the primary difference between the two models being body style (estate vs Sportback fastback). The TNQ is calibrated for the demanding requirements of the RS application: handling 800 Nm of torque from the 4.0 TFSI biturbo V8, managing power distribution through Quattro AWD, and integrating with the 48V mild hybrid system’s energy recovery and boost functions.

The 8-speed automatic in the RS6 and RS7 is programmed with multiple operating modes — Comfort, Auto, Dynamic, and RS — with shift mapping that ranges from smooth, early-shifting economy operation through to aggressive, late-shifting performance logic under RS mode and Sport driving. In Comfort mode, the transmission is near-imperceptible in operation; in Dynamic and RS mode, it delivers shift times that rival dual-clutch competitors while maintaining the torque converter’s advantage in high-load, high-torque applications.

Transmission replacement on the RS6 and RS7 C8 is an expensive operation through official Audi supply channels. A 17,546km, 2021 TNQ unitprovides a cost-effective solution at a mileage where all components remain in excellent operational condition, and at a specification — DJPB engine compatibility, MHEV integration, Quattro output — that precisely matches the original equipment.
