Fuel Computer Data Error

[Dom]

Hey All,
Just started getting this on my Message Center: "Fuel Computer Data Error." The trip odometer and odometer actually display hash marks when this happens.
It's been intermittent and when I shut the car off and start it back up, the error goes away.
Also, this started happening about a month ago. My car will not shift into
4th. The car goes from 3rd to 5th even when I manually shift. The gear selection display also does not display "D4", just "3" and "D5."
Seems like the electrical gremlins are starting to creep in. I have an '02 LS V8.
Thanx

Had that come on when I removed the fuse for the traction control system in the fuse panel under the glove box. Maybe check the fuses first and make sure none are loose? Beyond that it sounds like a dealer trip. Electrical issues are not fun or easy to track down.

obviously the shifter thing is separate...
if you pull your center console apart, i bet you'll find the D4/D5 microswitch isnt working properly. yes, there is one in there, i missed it first pass.

you can carefully take it apart, without snapping the little clips, or losing pieces, and fix it. i think the spring in mine simply got caught. just make sure you carefully note the orientation of everything. its basically a "diving board" with a spring running parallel from the middle to "hinged" end. pressing the shiny metal lever simply causes the diving board to flip the other way.

you can manually move the diving board with the ignition on and see if you then get D4. (pressing the switch puts you in D4). If it still doesnt work, theres a shift sensor on the side of the transmission that may be the culprit, but you may as well check the 5 cent switch first.

you cant order just the microswitch, but i believe burgess something is the name of the company should your switch have no hope. do a search on burgess switch with the numbers on the side of the switch.
