Another A6 to M6 Thread
I'm getting ready to drop the 6l80 out and put in a t56 and 3.42 gearing. I figured I'd start here. After hours of research I thought I'd just make a post. I'd like to compile info and contribute as I go along with the swap in the coming months.
What I have:
- 2006 MT Wiring Harness
- 2007 T56 w/ Diff
- 2007 MT Pedal Assembly
- 2007 Rear Subframe
- Clutch Kit
- Master/Slave Cylinder + Remote Bleeder
- Torque Tube w/ Bell housing + Shifter Linkage/Shifter
- Seals/Misc "while you're in there"
What I want to know:
- Custom Wiring? (CPP/Make the car happy with the swap)
- BCM Flashing (Tech 2 or similar)
- MT Car OS (I have a matching OS tune)
I may have forgotten a few things. Wiring isn't my greatest skill. Ideally I'd like to tackle the wiring before I start the swap so it's as plug and play as possible. Any input or help would be appreciated.
Updates:
- Aug 9, 2022: Auto/MT wiring harness pinouts mapped.
- Aug 15, 2022: Auto/MT ECM pinouts mapped.
Notes:
- Aug 15, 2022: Custom harness is needed from the transmission harness to the ecm. Luckily it's all close to the ecm Already. A few wires will need routed from the clutch pedal.
