Hello, I am having a problem with my 94 Camaro. Any help would be greatly appreciated. I have swapped a T-56 in my Camaro that had 4L60E originaly. I have a problem with the speedometer. It reads too low. How can I correct the reading? Everything else works fine. I've even reprogrammed the PCM. I also tried the Cyberdine(sp?) calibrater with no use. Fahad
