Historical Variants

1974-81 Transtar II

The predecessor of the first Transtar was the 1965-68 CO-4000 (which was replacing the DCO-400 Emeryville). In 1968, the company unveiled the Transtar, also known as CO/COF-4070A and as COF-4090A (with a raised cab).

An all wheel drive model was made on the Transtar basis from 1970 to 1972: the Unistar, or Universal four wheel drive with no transfer case. This truck has a modified grille, bumper, and front corner design.

The Transtar was replaced in mid 1974 by the Transtar II, a.k.a. CO/COF-4070B.^[3]
