Pressure control solenoids are current-controlled proportional valves, and what B and C mean depends on the design: on GM's clutch-to-clutch automatics they are the pressure valves of clutches 2 and 3, on GM's CVT B is primary pulley pressure and C line pressure, on Jatco CVTs B is the secondary pressure valve, on Saab's AF40 B and C are clutch valves SLC1/SLC2. P0795 is the general code for valve C. No manufacturer document available to us uses it; GM's 8-speed uses only P0796/P0797 for its clutch 3 valve, Saab's AF40 only P0798 for valve SLC2. Sub-codes for performance, stuck on, electrical and intermittent follow (P0796–P0799).
