Problem solved.
Just spoke to the Mechanics that Installed the Gears.
They though it was a 3.73 gear set instead of 3.08's.
Used a 3.73 Reluctor.
FWIW going through the entire ABS system with another Mechanic.
Learned a lot about them.
Here are some links I used to study and troubleshoot the issue.
I learned to read Engine or ABS Codes without a Scanner.
