Title: C6/B7 6HP19A gearbox to C5 5HP19 swap Post by: BlackT on February 22, 2021, 12:09:50 PM I am planing to upgrade 5hp19 gearbox to 6hp19 in audi C5 2.7 TT.
As I seen on forum M7.1.1 2.7TT can be paired with 6hp TCU. And looking to shematic TCU only need power and canbus to work. Also I see that C6 have samo immo in TCU so I am planing to get everything from late B6 or B7. Diff gear ratio as far I can see are same on 3.2 FSI C6 and C5 2.7 TT. So I can leave rear diff from C5 on car. Is this is possible swap to get everything work? Title: Re: C6/B7 6HP19A gearbox to C5 5HP19 swap Post by: BlackT on February 26, 2021, 04:02:41 AM I can easily found gearbox from B7 2.7 TDI or 3.0 TDI.
From 3.2 FSI is imposible to find Now I have two questions: 1. Can gearbox from TDI communicate with petrol ECU? 2. Is it possible to flash TDI gearbox with 3.2 FSI sofware?

I use gearbox, flywheel and torque converter from 3.0 mpi a6c6 but not yet driven with boost. a6c6 2.7t swap.
