I’m getting the Limited Gears Availsble warning, cannot shift out of park - I located the manual release and there are no noticeable problems with the transmission.

Tested the alternator and battery, everything is working fine.

Changed the Stoplight Switch, and the problem went away for an hour.

Reset the computer, then the radio went crazy and was all static on every mode.

Then it ran fine for an entire day, but now the limited gears available is back and the radio says “CD error, please eject.”

2008 LR3 HS V8.

Im starting to wonder if the ECU is bad.

Any ideas?
