Maybe.... maybe not! Most transmisions can be easily shifted in and out of gear without the clutch if the RPM's are just right. When the RPM's are low, no pressure on the throttle and a neutral situation the shifter will slide into neutral.
Most truck drivers shift entirely without the use of the clutch on 13 speed road ranger trans., just using the RPM's and thrust..no big deal. The only time the clutch is used is at intersections when the truck is stopped.
The point is, neutral thrust and RPM's will make the trans. shift easily..into any forward gear, even the Tremic TKO 600...I've done it.
