Customer brought in with the speedo reading all wrong. He brought from another shop all they did was charge him was $1100 for a used tranny.
1270
Problem
Speedo read all wrong to the point where the rev limiter comes on and set the 1270 code. It even reads mph in reverse and the tranny does not not work. Even on the scanner it reads wrong mph. I need a direction to look at, I know its going to need a tranny,took out the sensor and it is covered in metal. So far i just changed the sensor to see if it would work and it still didnt work. Trying to get lucky
Update
This only has the output speed sensor no vehicle speed sensor
