fleajr Posted June 27, 2019 Share Posted June 27, 2019 I have a 1914 4 cylinder 4 speed manual transmission with factory overdrive in 4th gear. With the motor running or without running the only time it will change gears is when the car is NOT moving. I tried double clutching while driving and bringing the throttle down to idle but still no luck. Any help would be appreciated. Link to comment Share on other sites More sharing options...
Bloo Posted June 27, 2019 Share Posted June 27, 2019 What kind of car? Be sure your clutch disengages completely. Many brass era cars (my 13 Studebaker included) use a thick gloppy oil in the transmission, and RPM of the moving parts drop WAY quicker than you would expect. The first to second shift has to be done really fast or it wont happen. 1 Link to comment Share on other sites More sharing options...
Grimy Posted June 27, 2019 Share Posted June 27, 2019 Does your car have a clutch brake? If so, depress the clutch fully ONLY when the car is at rest; when underway, move the clutch pedal only to within about an inch of the toe board (depending on the clutch brake adjustment). Look for "fingers" with pads on their ends, adjustable by threads. 1 Link to comment Share on other sites More sharing options...
