Its all good, I figured as much but didnt want to go back and forth. The forward one is the ISS ( Input Speed Sensor) it does as described. The rear is the VSS ( Vehicle speed sensor ) and it measures the speed after gear multiplication whether it be up or down. With that being said if they were reversed the Computer would not be happy, it would not shift right.

I swapped the 2 speed sensor plugs around. Everything is good. Didn't have time to tune today. But when I do next week, how do you get the converter to stay locked under part throttle. I don't recall at the moment. Any decrease in throttle unlocks it. Thanks for all the replies
