okay, three continuitys.
G1, ended with Optimus primes return and the head/target masters.
Targetmasters, a continuation of the theme of the, well, headmasters and target masters oddly enough.
G2 set after those two, no idea what happens really, nothing major.
machine wars yeah, more of the same.
Beast wars interesting stuff here, set after G1 (dates unknown) but affects G1 due to time travel (the Dinobots (group) are named after Dinobot (individual) due to his sacrafice in code of the warrior, where he dies to save a mankind (megsy is about to destroy the plateu where mankind would eventually rise up, Dinobot stops him)
ends with the Maximals being defeated! sort of
Beast machines some time later, the maximals wake up on a Conquered Cybertron. they try to recclaim the planet through some less than savoury tacticts.
edit: forgot to note that Megsy utterly destroyed all transformers on Cybertron, because of his eternal hatred for organics (the predacons ahving taken organic form in beast wars) ofcourse megsy is unable to rid himself of his own form (dino/dragon) and is a bit self loathing through the series.
Robots in disguise the Decepticons and Predacons (differant groups, the Predacon council holds its origins to the swarm) allie to destroy the Autobots/maximals (same group, just the name has been perverted for some reason or another that i forget)
probably lost, dont remember.

Armada a differant continuity, and pretty much an Alternate realitie. somthing happens, that causes the war to turn out differantly, i think because Unicron Destroyed Quintessa instead of allying with them, meaning no Quintessons to cause more trouble.
pretty much the whole season is to set up Unicrons infulence, some cool stuff by sideways (a member of the swarm) and we learn that the minicons were created by Unicron to spark of the Cybertronian war.
Unicron was masquerading as one of Cybertrons moons, and used the minicons to start the war again as stated, the hatred from this helped to rebuild his power, that he lost last time he attacked (millenia, prehaps even millions of years previously)
Energon With Unicron "defeated" the Autobots attempt to destroy the Decepticons once and for all.
but they keep reviving Unicron for some reason or another, some stuff happens, kicker gets incredibly annoying and Primus is mentioned for the first time since Beast wars
Unicron is finally "destroyed" (explained in the show, Unicron cannot be truly destroyed as he wille xist solong as chaos exists, and chaos will die with the universe, so he's staying basicly)

Galaxy force:
who the heck knows where this sits?! US/UK have it as a continuation of Armada/ Energon Japan has it a seperate continuity.
Rumours say Primus will fight Unicron at the end of the series (heres a hopin) but this doesnt work with Energon/Armada very well (unicrons body having been destroyed)
so. well. frankly weve no idea.
as for comic continuitys (The UK one being best ofcourse

)
they are considered slightly alternate realities.
edit: a couple changes, stuff i missed/ommited mainly.
