Hi, my car is 2011 insignia automatic.
I purchased one of these tools VXDIAG VCX NANO, It will take a long time to be delivered.

Is it possible to replace the AF40 automatic transmission TCM in my Insignia with a TCM of the same part number form a Meriva, by installing it to insignia, delete the data then flash it with SPS gds tool, without a vci code of any form acces code from opal?

Also is there anyone in london or close to london who can do this programing?
If so please contact me with cost/price.
Thanks

receive my VXDIAG VCX NANO GDS2, I was able to program the donor TCM to my car with GM sps service.
No security code is needed.
