I have seen where the power supply to the solenoids is failed. Check the correct wire to verify power at the transmission. The computer will indicate that it is telling the transmission which gear to be in, but the solenoids have no power and cannot actually turn on. This is limp-in mode. It is definitely a power supply issue to the trans solenoids.

When you rest your codes there is a series of tests your ECU has to go through before you can pass emissions. this is done some people can reset the code and go before its sets the code again. on the 96 you can have 2 tests not complete for it to pass. basicly you have to drive the car a couple days for the tests to pass.
check the readiness tests wait until only 2 have not passed. then you should be good.so drive and check.

Just maybe your O2 sensors are not operating properly. They may be requiring your engine to heat them up to get upper temperature readings but not lower. You can easily diagnose these and all other sensors and problems by purchasing a Hains manual at your local Auto Zone or Advance auto store which will greatly aide you in diagnosing all your auto needs. And the fault symptom index at the beginning of the book will ease your troubles with professional one on one advice with step by step instructions. Its like having your own ASE certified mechanic at your finger tips. Good luck.

Sounds speedmeeter is going haywire. Like everything in today's automobiles they are made with plastic gears. Some can be unscrewed under the stearing wheel others are not. The problem with the brake light break pads were probably stuck.I would say that your speedometer is not removable to many people disconnecting them for low milage on vehicle when trading or selling.

How did the Battery test out?
Anything below 11.9v battery is dead.
So I suggest that you do not throw any more parts and check the battery again.

NOX is produced when cylinder temperatures exceed 2500 deg. The systems in place to reduce NOX are EGR and the catalytic converter.
If the number is only slightly higher than avg then I would suggest the EGR, make sure that any vacuum lines are attached and that the diaphragm moves freely, be sure not to damage the rubber inside the EGR.
Retake smog test, if numbers still out of range replace the cat.
