P0621 - indicates a failure in the alternator lamp curcuit.
P0304 - indicates a miss fire was detected in the #4 cylinder
U1040 - indicates a loss of communication with the ABS system
U1000 - Indicates a class 2 communication loss

None of those codes are relating to a transmission failure (P0700-P0702)

I would have a visual look at the transmission and verify that all electrical wires are connected and tight. Then I would have the transmission serviced if it hasn't been within the last 35,000 miles.

Have the trouble codes cleared and address the ones that return.

After that you may be looking at an internal transmission adjustment and/or repair.

Good luck.

What I can tell you, is to get the car out of the dealership

You don't go there for transmission work,you go to a
trans shop,unless money means nothing

How do I know if my car has overdrive?


Sunfires and cavaliers always reved a bit higher because of the way they are built but it is an AEOD transmission (Automatic Electronic OverDrive). Since I dont know what rpm and how fast you are going it is hard to tell if there is a probleme or not. I would compare with another similar car and decide what to do.

I have tha O/D OFF flasing in kia rio 2001


THAT IS THE OVERDRIVE IN THE TRANSMISSION
THE CAR MIGHT NOT WANT TO SHIFT TO HIGH GEAR OR OVERDRIVE SOME OF THESE CARS USE THE COMPUTER TO SHIFT IT TO OVERDRIVE AFTER IT GETS WARM THE THERMASTAT PLAYS A ROLL IN THAT WHEN THE ENGINE IS WARM THE LOOP IN THE COMPUTER CLOSES AND THE CAR WILL SHIFT TO HIGH/ OF THAT WON,T FIX IT THEN THE COMPUTER IS AT FAULT OR THE SENSOR IN THE TRANSMISSION IS BAD

Rpms rev. high before it will go into gear. and it wont go into overdrive unless you play with the gas and the gear shifter.


when was the transmission last serviced? it seems like the transmission filter is plugged and it takes the pump higher rpms to push fluid through try changing the tranny filter.,

It sounds like it may be an electrical problem. Maybe a problem with the TCM, or a sensor.
