I have problem in AUTO TRANSMISSION with my Kia Carnival 2003, when I start the car the trans works properly and gears shift smoothly but when speed up to 30 KMPH the gears slips and stuck. When I stop at the signal or drive long way its not shifting the gear nor its shifting back to start.

Please help.

Fluid level ok? Possibly heat is effecting trans solenoids function.

Also speed sensor input to ecm could be failing so trans is confused as to what to do.

Sounds like an OD problem. Funny no warning lights showing? Try reading codes?
