I don't have a picture. Scanner tool has no codes showing. However, it did say vacuum leak test failed. I've changed gas cap, cleaned mass airflow sensor, and replaced fuel pressure vacuum harness that hooks into the throttle body and on the fuel rail.

    What do you mean by overdrive? Do you mean it doesn't downshift when you push the pedal down a lot? – GdD Oct 23 '17 at 15:00
  • Check transmission fluid? I think the tranny problem is unrelated to the vacuum error, but obviously you should fix that anyway – agentp Oct 23 '17 at 15:07
  • It won't shift into overdrive it seems to sound like it's revved real high n rpms act like it shifts but it does not – Tracy Evans Oct 23 '17 at 15:25
  • @TracyEvans, So, cruising on the highway, for instance, your RPMs are high, like the transmission has not shifted into the highest gear? – JPhi1618 Oct 23 '17 at 17:57
  • Have you checked the transmission fluid level? Did you check the accuracy of the shift selector (is it actually in another position other than "D")? – CharlieRB Oct 23 '17 at 20:41
