doors with the Transtar 4300 conventional. In a significant break from precedent, the interior of the 9670 and its successors were designed without any intrusion of the engine or transmission (leaving a flat floor). The final Newport-series cabover sold in North America was assembled in 1998. Conventional In 1969, International Harvester introduced the Transtar 400 conventional. An update of the D-400 introduced in 1961, the Transtar 400 was a long-hood conventional fitted with the cab of the DCO-400 ("Emeryville") cabover. In 1971, International Harvester replaced the Transtar 400 with the Transtar 4270 (short-hood) and 4370 (long-hood) conventionals. A completely new design with a much larger cab, the Transtar cab would be shared with the all-new Paystar introduced in 1973. In 1985, the Transtar 4370 saw a major update and a renaming. Dropping the Transtar name, it became the International 9370, an introductory model of the International 9000 series. In 2000, the cab saw a major redesign for the first time since its 1971 introduction. Design overview Although using a wide variety of chassis frames for each vehicle, the 8000/TranStar is produced with the same cab as the International DuraStar (with which it shares a larger version of its grille), the ProStar, WorkStar, LoneStar, and the discontinued TerraStar and XT truck lines. As it is designed as a regional vehicle, the exterior of the TranStar did not include the fuel-efficiency enhancements integrated into the long-haul ProStar.
