The transmission in my '02 Accord slips a bit and I have Check Engine Code P1793. What does that mean? Is this something that requires repair or is something that will an annoyance that doesn’t get worse over time? The car has 80k on it.
You will likely end up needing a transmission overhaul or replacement. Those transmissions from that time period are well known for being problematic. You can find a lot of info by general internet search.
Take it to a local, independent (i.e. not a national chain) shop that specializes in transmissions. Have them evaluate it and prepare for bad news.
is it a V6? If so, you may be able to get it replaced for free or a heavily reduced price. Honda extended the transmission warranties on the 98-02 V6 Accords to 7 years/100,000 miles because of known problems causing them to fail. You’re over on the years but not on the mileage. It’s not at all unheard of for Honda to goodwill repairs like this.
