The throttle positioning sensor "TPS" is bad it will cause a late shift. Also check the 10 amp fuse in the fuse box if it is blown will cause of failure of the solenoid pack. You'll have to tell me a little bit more what the transmission is doing and don't leave anything out, transmission problems are hard to fix.
