This all started after i got my tranny rebuild....the speedo goes all over the place and the tranny won't shift right.....now i replace the sensor and it's fine....about a month later it goes again....i replace it again and the connector this time....it's fine for about another month then goes again....why is this happening? The tranny was pulled and went through and it looks like the day it was built. While the tranny was out i sent the convertor out and that was fine too.
