Reply to "TMCC only goes full speed"

What model?  How new?  If this is the older model with the TAS EOB, it's probably the tach reader, usually a broken wire at the base.  If this is the newer version with the ERR Cruise Commander, try reprogramming the TMCC ID and engine type, typically AUX1/4 for 3rd Rail steam and AUX1/8 for diesel.
