You could say he always had it, just hadn't invented it yet.
When he was beaten up by Aokiji, then CP9, he knew he had to learn some stronger techniques. Using his rubber body as a pump to speed up the flow of his blood, was one idea he had. So it's something he just learned to do.
At the battle of Marineford, it was shown that Kizaru was still easily faster than Luffy's Gear Second speed. It is not known if Luffy's speed has increased further after the timeskip.
first i use my legs to pump blood to higher rates, then i have my metabolism to be so high, i sweat. then it evaporates, which is why i look like I'm steaming. my stance helps get the process to stabilize.
He ate the gum-gum fruit so now he can stretch his body to any length, and is very strong besides that.
Luffy is stronger than Jinbe. If luffy fights Jinbe seriously, he would win..
Dragon saves luffy from Smoker in Loguetown, although they didnt meet face to face, and Dragon hides himself from luffy, that was the only instance that Dragon met Luffy so far

As of the latest issues, Luffy has only used up to Fourth Gear.
Aokiji soundly defeated Luffy in their first encounter. Luffy had no way around Aokiji's logia-type powers. Now Luffy's trained his haki skills, he can at least hit him, and it would be interesting to see how the heat generated from Gear Second may work against Aokiji's frozen attacks. However now Aokiji has resigned from the marines, there doesn't really seem a reason for them to fight.
I think Ichigo Kurosaki would kill Monkey D. Luffy because Ichigo has bankai and that would decently damage Luffy. Also because Ichigo is a soul reaper (the good kind.) However luffy's haki is really strong he could use Bososhuko haki to defend himself and make powerful punches and also luffy would read ichigos attacks like a book (except hes to stupid to read)with kenbonshuko haki and he could destroy ichigo with gear second and third
after using gear third at ennies lobby..he wanted to open a door...

He learns gear third during his fight with Rob Lucci trying to save Nico Robin from the world government.
a noisy second gear in your transmission is that your second gear might have broken gear tooth which is mostly the problem with my cars.either the second gear on the counter gear or the second gear itself.
Luffy defeats Doflamingo with his near 'Gear 4' techniques. Gear 4 blows air into his muscles, and hardens his skin with haki, without making it any less elastic. This let him deal incredibly powerful punches by contracting his arm into itself and letting it recoil. In the last blow of the fight, Luffy used a bit of Gear 3, inflating his compressed arm to giant size, smashing through Doflamingo's attacks and defences, and punching him straight through the bedrock into the underground port.
