I had a guy check my sons 99 accord, he said it needs transmission work i think he said something about the spags never heard of this he said it would cost about $850.00 and take a few days,i then call a transmission shop the guy says its no way he could've told me the car had this kind of issue without putting it on a machine he also said if that was the problem the car wouldnt be able to move,who should i trust?
