A6 C6 Corvette wont downshift unless I pull the ABS FUSE

[shoaf85]

Just finished tuning this car on the dyno and it shifted perfectly on the dyno in "D" and in "S" mode. Once I pulled it off the dyno it would shift up through the gears once but would never downshift again. Even if I stopped and put it in reverse/park it would stay in the highest gear that it shifted to before stopping. I started thinking well in the dyno the abs lights were on and it did fine. I pulled the abs fuse and the trans shifts perfectly fine now. The car has a turbo kit on it with some id1000 injectors and that is it. I have made some very simple changes to the trans tune like I typically do on all the A6's I've done but never seen this issue before.

LMK if I am missing something or if any of you have ever even heard of this!
The car is tuned with a ZR1 map sensor using VVE still
2 bar vve 4.hpt

Try putting the traction control settings back to stock.
