G'day

The speedo and odometer has stopped working and the tacho works sometimes. Do you think it's tome for another cluster or could it be something else

hard to say without looking at it properly. ive seen a few speedo transducers die which would explain the speedo and odo not working.
if your car is a 4spd auto does it change gears properly? because if its a faulty transducer the auto wont change out of 3rd (limp mode)...

Thanks for answering, its a 3 speed auto
