Discuss the causes and fixes for P0762 OBDII Code

  • Solenoid C gets a bad rap, in that it almost never fails. This solenoid only supplies pressure to operate the reverse clutch & the direct clutch (3-4 clutch). If the solenoid is defective then neither reverse or 3rd & 4th gear will operate properly, but 1st & 2nd gear will operate fine . Fluid passages in the valve body or the side plate (located on the driver's side of the Mazda 3 Trans (Mazda P.N. FN4A-El) could be blocked & both can be accessed without dropping the trans. If the error code happens only in reverse or when shifting to 3rd gear, the problem is in the respective clutch or a clogged fluid path. The problem is almost invariably the respective clutch piston. I normally replace the respective clutch, which can be done without dropping the trans. Loosening trans bolts, mounts & motor mounts will allow enough room to replace either the direct or reverse clutch (located directly behind the side plate.. Given an accurate description of any Mazda trans problem, I can pin point the problem. Failure of metal parts is rare & a whole different problem. You may clear any error code by briefly removing the positive battery terminal.
