Getting a code 720....
Ok, here's the deal. My buddy has a 99 R/T and has some minor mods to it (Exhaust, cold air intake), and wanted to try a performance tune from my 3715 that I have.
I downloaded it for him and he took it for a good run. After he got home and started to drive it again, the check engine light came on.
code is this: 720 The Output Shaft Speed Sensor doesn't match the reported vehicle speed
I put the truck program back to stock and reset the code but it came back.
Coincidence? Bad sensor? And where is the sensor located on the tranny?
