Transformer funerary practices

Don't worry, Wheeljack is only resting. Windcharger, however...

Ashes to ashes! Junk to junk!Wreck-Gar

You can learn a lot about a society from how they treat their dead.

Generation 1

Autobots

The Autobot honored dead are placed in massive mausoleum spacecraft which are left to drift in space. These spacecraft feature a docking bay, presumably to allow Autobot pilgrims to pay their respects to past heroes. It is unknown if these mausoleums have defenses to protect the dead against disrespectful Decepticons. Dark Awakening

Cue bagpipe music.

A facsimile Optimus Prime was once buried when the Earth-bound Autobots believed it to be the real Optimus. This was a departure from Cybertronian traditions, but according to the Autobots present, adhering to Earth traditions was 'what he would have wanted'. When he died for real (temporarily) a short time later, his body was instead shot into space, suggesting that maybe he wouldn't have wanted a burial after all. Resurrection! Funeral for a Friend!

When Rodimus Prime was believed dead, Springer said they would take the body back to Cybertron for internment. Five Faces of Darkness, Part 2

The Autobots have been known to dispose of a fallen enemy by giving them to the Junkions, with Ultra Magnus intending to send them to collect a fallen Galvatron. The Dweller in the Depths

When Ultra Magnus was shot dead by Sixshot, he was given a burial at sea in a glass coffin decorated with Christian imagery, on his favorite planet, Earth. Ultra Magnus Dies!!

The murdered security officers Bumper and Fastback were given a state memorial service with internment in coffin-like crypts adorned by holographic remembrance avatars. Megatron Origin issue 3

Decepticons

Ooooh, shiny...

The Decepticons create markers bearing the likeness of their dead, lit by an eternal flame. Superstitious Decepticons believe a deceased Transformer's spirit may linger near its marker, and it is bad luck to disturb one (after all, they do have ghosts...).

It is unclear if these mark the place where a Transformer's remains are stored or not, but at least three Transformers have markers in two locations.

Beast Era

Maximals

For Maximals it is customary to hold a wake where their friends and comrades reminisce about their memories of the fallen.

Predacons

Out, out, brief candle...

The Predacons recycle their dead with honors. It is considered to be an act of great respect to the dead, though Maximals might disagree. Fallen Comrades When Dinobot sacrificed his life to save humanity's future, the Maximals recycled his body in honour of his Predacon heritage. Code of Hero

Transformers Animated

Autobots

An Autobot crew who performs a noble duty and dies in battle is given a proper funeral service. The one who knew the fallen comrade the most gives the eulogy, respectful or not. Dispatches

Before a funeral, the remains of great heroes are placed in an open coffin, carried by their comrades, to be displayed to the masses after a victory. Endgame, Part II

In some cases, if a notable figure is not quite dead yet, they'll be put into stasis and their alt mode recycled for other purposes until a cure could be found. A Bridge Too Close, Part II Transwarped

Decepticons

A great Decepticon leader, such as Megatron is given a proper funeral service. It is not uncommon for one person to erect a statue in the honor of the fallen in particular. The Arrival issue 1

The remains of executed traitors are unceremoniously thrown into nearby rivers or garbage piles to rust where they lie. Mission Accomplished
