No check engine light

O.k.,with no check engine light this issue here may be a fault with debris build up in the transmission valve body itself.I have seen debris partially plug ports in the valve body causing this type of fault here needing repaired.Usually all that is needed is to have a transmission fluid flush performed to remove the debris from the transmission valve body.

In some cases it can be a shift solenoid that gets debris in it as well and usually the flush will free up and remove this debris.

I would have this done to see if this resolves the issue here.If it does not then have the shift solenoids tested for any issues.
