  1. Low on transmission fluid will cause the vehicle to act this way. If the fluid level is full, you are looking at a rebuild.

  2. AS far as fluid levels trans is full Would it happen to one of the sensors?

    updated.

  3. If the fluid level is full(when in park and engine running) and is bright pinkish/red. It is possible that maybe the VSS – Vehicle speed sensor or Shift Solenoid is sticking but with it making some sort of noise… is it a whining noise? or a banging noise?

  4. I thank you for your help! I was mistaken about the noise there is none, When this happens it feels like trans is trying to shift like there is a gear missing then it shifts and goes on down the road. Is it the speed sensor or shift sol?

  5. From your last description, it sounds like the VSS is telling the transmission to shift when it should but the shift solenoid is being lazy or sticking a bit.

    If you haven’t changed the transmission fluid and filter, it might be a good time to do so. Make sure to use the Mercon V fluid when refilling.

    If the fluid is burnt looking, it is still possible for the internal clutches to be worn and a rebuild would be needed.

    Since it seems to shift in the other gears just fine, I would rule out the Electronic pressure control solenoid. But the shift solenoids may be sticking and or lazy. It is possible that replacing them may be needed.

  6. Thanks for your help! Are all 4 shift solenoids internal? What is the solenoid on the drivers side of trannie out side ?

  7. Are all 4 shift solenoids internal? YES

    The location diagram I posted shows the valve body which can be seen once the transmission pan and filter are removed.

    Not aware of any external solenoids, there is an external VSS – Vehicle Speed Sensor

  8. Thanks again!!!!! Do I have to replace all 4 sol. Or is there a way to fix the problem, If you would talk me through with what I have to do to get this monkey of my back I would be in debt to you.

  9. If you haven’t changed the transmission fluid and filter, it might be a good time to do so. Make sure to use the Mercon V fluid when refilling. THIS IS WHAT I WOULD DO FIRST!

    If the fluid is burnt looking, it is still possible for the internal clutches to be worn and a rebuild would be needed.
