Speartech 6L80/90e tap shift harness
Ive had it about a year and a half now, just no desire to install it. You have to run a corvette tcm tune or similar bc it does not require a bcm reflash.
This is for anyone that swaps a 6L80/90e in, not for someone that already has the 6L80/90e
I paid 145 shipped to my door, so 125 shipped obo, depending location
