Can the transmission be reprogrammed to eliminate a hard downshift?

My 1998 Camry V-6 has 128,000 miles and runs excellent. There is one issue. When slowing to a stop, the last downshift sometimes comes with a slight bang. Is it possible for this to be corrected with a adjustment of the computer. A reprogram? I've regularly had the transmission fluid flushed by Toyota.
Do you
have the same problem?

Check to see if there are any soft codes stores by the computer. There could be an issue with one of the shift or transmission control solenoids.

Damn. That looks like a cool scantool, saturntech. I want one now. Lol.

Ferrari, the one saturntech mentioned is one I would recommend. You can also check your yellow pages for shops that will scan for all codes free.

I read the specs and features. For a basic scanner, it reads pretty nice.

A hard code, yes. But not a soft code. Transmission faults normally set soft codes, unless they're really serious.

Doesn't the line pressure solenoid sound like it would likely be more of the problem?

Like I said, it could be any one of the solenoids or valves in the transmission.

Without a codes scan first then a electrical ohmns test and possible a transmission pressure test then your just plain guessing.

Saturntech9: Is the code scanner mentioned before, the correct scanner to find these so called soft codes? Or would I need a better one? I am not getting a check engine light.

It would read the P codes which are powertrain codes and the U codes which are communication codes. So it would read the codes you need. Also to properly diagnose transmission issues you need a transmission pressure tester to read the transmission pressures and a multimeter to check wiring solenoids etc.
