I had my gearbox rebuilt in 2014.

Some time later it started lighting everything on the dash and went into limp-home mode. Called the gearbox specialist and they said it was definitely an electronics issue. Waited a few months and obtained the replacement TCU (thanks Prestige) and it fixed my problem instantly. My original TCU was immaculate; the replacement was not quite as clean and tidy but it certainly did the job. Still working fine 6 years later.
