I assume that you replaced the radiator, or had the trans cooler replaced, since that is how coolant gets into the trans. If this is what happened, the coolant becomes emulsified with the trans fluid, it caused a major mess inside the transmission. Just changing the fluid is not the fix. You will either have to have the trans removed, disassembled, and thoroughly cleaned and rebuilt,or replace it.

Inside the key close to the blade is a small chip that the ecm needs to receive the code from to allow it to start the engine there is a pickup coil in the plastic surround the steering lock barrel if the connector is dodgy you can get a key error or if the chip has moved out of position in the key same result
the code has to be read and accepted before it will let the engine start

Is it in reverse? If not remove gaiter from gear lever and adjust gate

It should I don't think there was that much a change from 99-02 few cosmetic and performance changes

OK, first open the relay box that is next to the batt, then remove the yellow relay(pos# 3 from driver to bumper)(theres two yellow relays) then with a little piece of wire plug it in the horizontal slot and then in the vertical one that is right on from of it for 1 to 3 seconds into the car star. Make sure the key is in on position and Ebrake is on, if auto trans, put in Park, if Manual trans, put in Neutral, because you will jump the starter motor relay, and the engine will spin as soon as you plug in the wire.

could be something else like the cable that releases the park ?? if it appears ok then renew the ignition lock ,nice job this one because its in the middle

Have you tried to jiggle the steering wheel when trying? Sometimes the pin will not line up with the holes and will cause this.
