Wear in the primary pressure regulator bore is common in Jatco/Nissan JF010E (RE0F09A/RE0F09B) and JF011E (RE0F10A) units. This wear minimizes line pressure control resulting in chatter on acceleration and pulley breakage.
Sonnax oversized primary pressure regulator valve kit 113741-09K restores accurate pressure control.

Vacuum testing at the port(s) indicated fails to hold the recommended minimum in-Hg, or if wear is visually detected.
