Moved to it's own thread, since I couldn't figure out what to do with it.
I suspect a TAHAO is a Tahoe.
So what you should do is find a forum devoted to Tahoes not HHRs.
Usually that code means a bad TCM or the wires between the TCM and the transmission are compromised.

An HHR or Tahoe in Nigeria! Cool, have a look at the fuse panel for the TCM fuse it maybe loose or blown.
Check wire harness connections they might have worked loose.
Check ground wire connections , same issue.
Also if you could clarify if it's an HHR is it an '08, how old is the battery? Check the under hood fuse box and the positive cable connections.
Most important welcome to the site!

Hello Henry,
Because of the differences between HHRs and the Tahoe/Yukon models made by General Motors, I'm going to suggest you check out/join our sister forum by clicking the link below.
Tahoe & Suburban - Chevrolet Forum - Chevy Enthusiasts Forums
They are really nice folks over there, and they're "Fluent" in Chevrolet Tahoe's from bumper to bumper.
