The Transformers #176

Goldbug, Getaway, Joyride and Slapdash arrive on the planet Nebulos, to have the Nebulans build a new body for Optimus Prime into which they can download his mind. They discover that two Decepticons had earlier appeared, and had binary-bonded with two Nebulans who can transform into their power packs. The Nebulans rebuild Optimus Prime, who undergoes the same binary-bonding process with the Nebulan Hi Q. Getaway, Joyride and Slapdash also agree to undergo the same process with three other Nebulans. After dispatching the Decepticons, the five Autobots depart Nebulos to head back to Earth.
