A guitar player might have trouble with bass for one reason in particular: string gauges. Electric bass strings are about 10 times thicker than the most popular gauges.
That's what Jaco and Mark King did/do. Both of them started as drummers. Larry Graham and Louis Johnson as well; they were compensating for not having a drummer in their respective worship bands.The easy answer is: play like a drummer.
Bass guitar was the first stringed instrument I learned to play. I took lessons for about 6 months until I knew enough where I could learn things on my own, and I've now been playing for about 15 years. I sort of taught my self guitar based on chord charts plus my existing knowledge of the fingerboard, so my chord fingering is probably not very traditional. Anyway, I've been reading a lot of TalkBass forums lately and have seen discussions about guitar players playing bass coinciding with many people having an aversion to playing bass with a pick. For most rock influenced music I play, I like to use a pick, so I've started to wonder if my playing style would be what some consider to be playing like a guitar playing bass even though I would never consider myself a guitar player. However, I have been told by probably the best guitar I know that I am "the most solid bass player" that he's ever played with, so I guess that should count for something.

That means you have great timing. I'm a "solid bass player" that keeps time extremely well even in weird time signatures, but not so flashy like other bassists. I feel the groove and fill in between guitar and drums, but don't go for solos or that extravagant stuff. Each band has different requirements, but I will say keeping time and the groove are the first and foremost role of a bass player. And consequently, that's what a lot of guitarists lack when they play bass.
