Part of Lesson Plan: **Shift linkage, Interlock, & Detents (updated) by Beau Sunahara

Activity Overview / Details

The teacher will revisit the lesson on sychronizers and how the sleeves fit into the shift-forks.

The teacher will explain that if a manual transmission ever shifted into two gears at the same time, a cataclysmic failure in the transmission would occur.  To prevent this type of damage, shift-forks have an inter-lock device to allow only one shift rail to be moved at a time.

The teacher will ask for questions at the end of the lecture to clarify explanations.

Students will take Cornell-style notes during the lecture.

The teacher will need to express this is not the sole way to lock out gears, but this is just one example of how a transmission is able to lock the other rails out.
