My vacuum control valve does not have a lock nut and there are not enough threads to add one ....also the unit does not have a cap over the adj nut ...does this matter
when I adj the vacuum so that the transmission no longer flairs it reverts back to a high volume after sitting over night resulting in flair
where can i buy a new one or how can this one be repaired
this link shows the unit
