Just had my tranny done with the correct speedo gears installed and BRF code. But my speedo still reads incorrectly (speedo reads 50mph when actual speed is like 80-90mph). There is a possibilty that the rear gears are a 3.08 from a monte carlo the previous owner used to have.
My car from a standstill cannot fry its tires at any moment unless brake boosted (max boost 18psi per run). I was told that a 4.10 gear works good on these cars from the buick tranny shop. So rather than going to the stock ratio, should i upgrade?
