Transtech
Transtech was originally planned as the follow-up to the Beast Machines toy-line and cartoon.
Fiction
Story-wise, not much is known. It likely would have picked up on technorganic Cybertron following the events of Beast Machines. A Mainframe CGI animated series to support the line was likely in the discussion stage at some point.
Toyline
The characters transformed into Cybertronic vehicles that in many cases had animal-like features/deco. Cheetor was a Cybertronic race-car with a cheetah-like paint job, for instance, and Prime (confusingly invoking Optimus Primal) was a truck whose front end looked like an ape's face. Designs were done by Draxhall Jump and had somewhat less traditional robot modes (Cheetor had large hoop "wheels" for shoulders and feet, for instance) and didn't always resemble older versions of the character very closely. The overall aesthetic being somewhere in-between Beast Machines' odder moments and the new 2007 movie designs. Many of these designs were first shown at BotCon 2002 (apparently without Hasbro permission as they were pulled from the booth halfway through the show) and then subsequently available online.
The line would have included Maximals carried over from Beast Machines:
returning Beast Wars character:
returning Generation 1 characters:
and at least one new character
Design sketches for a Megatron and a Scavenger of uncertain identity also exist.
The toyline got to the early hard-copy prototype stage, and some prototypes, including Cheetor, Starscream, and Prime, have surfaced. None of them apparently reached a stage of production where real usable molds were created, and so future release is extremely unlikely.
When Draxhall Jump made their design sketches for Transtech available, they also included a number of designs from other lines (such as GI Joe), but put them all under the 'Transtech' header for their web page, causing a bit of confusion. This artwork included a work-up sketch of Soundwave as a souped-up blue boom-box, which is often mistaken to be a member of the Transtech line.
Cancellation
The reasons for Transtech's cancellation remain unknown for certain, though over the years a number of possible reasons have been speculated, among them: negative fan reaction to Beast Machines, conflict with Mainframe, difference with Takara, or simply a desire to go in a new direction. The most likely explanation is not a singular culprit, but a number of corresponding culprits, perhaps culminating in the closing of Hasbro's Cincinnati offices and departures of staff, followed by the subsequent relocation to Hasbro's central offices in Rhode Island.
The cancellation of Transtech led to the Japanese "Car Robots" cartoon and toyline being imported as a stopgap measure while Hasbro and Takara began to work together to jointly create and launch the Armada line.
Out of all the concepts, only one made it out to release. An Optimus Primal from the line were released into the Robots In Disguise line.
