never heard the 5 auto on gx model the , as i kno of the 5 speed was mainly on the GPX not the GX. Nun the less a sticking solenoid or loss of pressure when going into 5th on in 4 auto cases when the TCC is engaging. If there is a loss of pressure the TCC can have low pressure issues engaging in 4th or 5th an oil change would be a good thing. Using fluid specified to Diamond SPIII , or Mitsubishi Diamond fluid.
If its never been serviced a good service should help
