Historical Variants

The first Transtar was the 1965 CO-4000, which replaced the DCO-400 Emeryville. Another early model was the Unistar, or Universal four wheel drive with no transfer case. By the early 1970s, the company produced the larger CO-F4070A and 4090A.

The Transtar name was used for the Transtar 4300^{[citation needed]} which was in concurrent production with the Transtar II cabover in the 1970s.
