Anyone ever encoutered a CDTC 77-1 Power Transmission System Failure code on an '03 Pilot?

Just did a 240,000KM/150,000mile major maintenance service on my '03
Pilot and one of the notes made by the tech was that the CDTC 77-1
Power Transmission System Failure was detected. I'm guessing he hooked
up his thingamajingy to the underside of my steering wheel and scanned
for error codes. The note went on to say that he cleared the code, but
to monitor it.

I haven't noticed anything unusual at all with my transmission at any
give time but I am greatly concerned since transmission repairs are
expensive.

I've followed the severe scheduled maintenance religiously thus far
and I'd be supremely disappointed if my Pilot ends up with a tranny
problem. My buddy's '02 Toyota Highlander is still going strong at
280,000+ KM without any major issues and he hasn't exactly been true
to the Highlander's maintenance schedule.

Anyone familiar at all with this code? And what sort of things should
I be on the look out for with this type of code? Thanks.
