The 3600 was used exclusivley for The Thomas Vista The 3400 was replaced by the 3200 when the 4000-series trucks were replaced by the DuraStar currently, the 3200 is used only for transit bus, commercial bus, and specialty vehicle applications.

Bus both developed products based on the 3400, but the chassis became more popular in the transit and specialty vehicle industries instead. In the school bus industry, Mid Bus and U.S. Today, school buses like these are known as Type A-2 buses. The 3400 was a chassis designed in the same fashion as a Type A cutaway school bus, but with a heavier-duty vehicle (the Navistar 4900) as its base. Declining school bus sales during the 1980s and 1990s and corporate politics led to Ford Motor Company and General Motors to stop producing full-size bus chassis altogether. International, the parent company of IC Corporation, was the lone chassis manufacturer that sold bus chassis to other body manufacturers. By 2004, there were only three body manufacturers (Blue Bird, IC Corporation, and Thomas) and three chassis manufacturers (Blue Bird, Freightliner, and International). In 1989, it was a common practice for buyers of conventional-type school buses to select different types of chassis for a given body manufacturer (for which there was a wide variety) there was a large number of possible combinations of Type C buses available. When the 3800 was replaced in 2005, the school bus industry had changed from its introduction. The 3800 was discontinued by Navistar in 2004, after outliving the International 4000-Series by three years it marked the end of the International Harvester S-Series, introduced a quarter-century earlier.

Dubbed the International IC, these wore vertical grille slats instead of horizontal ones seen for over a decade. In 2002, Navistar made the first visible styling changes to the 3800 (or any 4000-Series truck) to mark the transition of its subsidiary body manufacturer from AmTran to IC Corporation, the hood was redesigned for its conventional-style school bus.

In 1995, along with all other International medium-duty trucks, the 3800 received chrome hood badges denoting the model series and its engine type the grille badging changed from red to chrome. For 1992, it received a redesigned instrument panel with larger gauges. Over its production life, the 3800 (and its variants) received few visible changes throughout its production run. The 3800 (and lighter-duty 3700) were introduced in 1989 and sold alongside the S-Series school bus chassis until it ended production. In 1989, Navistar redesigned the S-Series medium-duty conventionals for the first time since 1979 the medium-duty trucks were renamed the 4000 Series.
