I donít know if this has been discussed before, I have a 98 Hardbody, the problem is that at times the speedo doesnít work, the problem is clearly electrical.

When the gearbox was overhauled I had them check the electronic sender unit, ok. I was not present when the next test was performed, but was assured that the dash receives the signal.

I can be driving at any speed on a smooth tar road, when suddenly the speedo needle either comes to life, or dies, none of the other instruments are defective or effected.

Anyone with a quick solution
