If I track it in reverse it all works ok with plenty of power and goes in and out of normal speed and fasttrack speed. The right hand motor is feed off pump1 and the left hand motor is feed off pump 2.the fast track pedal / switch on the floor that controls the solenoid all works ok as does the solenoid. I don't think its the pump 1 as it works ok in reverse. Anybody have an idea whats wrong with it.I suspect its the track motor ?. Thanks Gary
