th400 users...speedo question what do you use to make the speedo work after going from t56 to th400?
i remember hearing something about a part from a 1 ton truck application with a 4l80 or something.

Does your TH400 already have the sensor in it? If so you just need to splice in the required connector with the T56 speedo connector. If not you'll need to get a sensor put into the tranny to replace the mechanical sensor.
