Since DC's series didn't start until '84, they only did 8 issues set between TWOK and TSFS, comprising four distinct storylines (in fact, the comics adaptation of TSFS came out in between the two parts of the story spanning issues 7-8). So that's probably only a couple of months' worth of events.
In one respect, it seems there should be something in between, because the Enterprise has significantly more hull damage at the start of TSFS than it had at the end of TWOK. The story in issues 7-8 does involve the ship getting banged up by torpedoes, although it doesn't explain how the new battle damage includes some of the exact same scars inflicted in TWOK.
Other than that, the most significant inconsistency is the bit at the start of TSFS where Phil Morris's character asks if there will be a memorial service for Spock. I could buy issues 7-8 (dealing with Saavik's pon farr) getting Kirk preoccupied with Spock's death again, but it's hard to believe there wouldn't have been a memorial before then.
Still, it's better than DC's attempt to fit The Voyage Home into their continuity. They managed to reset things pretty well for the most part, but the transitional storyline asserted that the captured Bird of Prey had been in the Excelsior's shuttlebay the whole time, even though the issues set just after TSFS correctly showed that the BoP was far too big for that and needed to be towed behind the Excelsior, tucked under its fantail.
