OKAY THE SPEEDOMETER DOES'NT WORK MOST OF THE TIME AND WHEN IT DOES THE TRANSMISSION WORKS FINE BUT WHEN IT DOES'NT THE TRANSMISSION ACTS LIKE IT'S CONFUSSED IT WONT CHANGE FROM FIRST TO SECOND LIKE IT SHOULD AND JUMPS INTO A LOW GEAR THE TRANSMISSION TECH. AT THE SHOP SAID IT THE SPEED SENSOR I REPLACED IT WITH A USED ONE FROM PIC- N - PULL BUT IT'S STILL DOING THE SAME THING . IS THERE A RELAY SWITCH OR SOME THING THAT WORKS WITH THE SPEED SENSOR OR SHOULD I GET A NEW ONE WOULD THAT MATTER ?

I would recommend a diagnostic test to determine the root cause. It could be a bad used sensor, but maybe not.
