AT 351000 kilometers my transmission would not up shift after slowing down or stopping unless I shifted the auto manually. Took the van to a tranny shop where a diagnostic chech showed my cvi pressure was too low. . . . . . worn out I was told. Not willing to spend $1600 for a rebuild I spent $16 for a bottle of tranny fix and as they say. . . . the rest is history. . . my dear old van is back to running the way it should. If I wouldn't see it for myself I wouldn't believe it.
