The radically designed Changer required a huge portion of your floor pan to be cut out. The very popular Fenton and Sparkomatic incorporated die-cast aluminum bodies in some models, which quickly cracked under heavy use. Most of these designs suffered in the durability department, as well. Hurst Shifters have a vast number of installation kits for just about every side-mounted 3- and 4-speed shifter. Thus, the shifter moves left or right to grab each gate.

The H-pattern design, for the most part uses a horizontal gate. The typical “H”- pattern shifter seems to have stood the test of time. Companies, such as Fenton, Sparkomatic, P&G, Hurst, and Mr. Drag racing puts a tremendous strain on linkage components, and a common modification was usually a custom floor shifter. To provide that positive shift feel, modifying column shift back to a floor shift became the thing to do when drag racing started to flourish in the late 1950s. The column-shifter design was a far cry from the positive feel of the direct-top cover shifter.

This Tech Tip is From the Full Book, HOW TO REBUILD AND MODIFY HIGH-PERFORMANCE MANUAL TRANSMISSIONS.

These new components required a redesign of the actual transmission to incorporate the addition of all these extra components. In order to create a column-mounted shifter, the actual transmission shift mechanism now had to have a series of external shifter shafts, linkage arms, shift rods, and levers for this design to be feasible. Automotive engineers in Detroit wanted to get away from floormounted shifters and create shifters built into the steering column. The shifter directly moved the shift forks. In general, prior to World War II, most vehicles had a shifter mounted in the top cover of the transmission. Today most manual-transmission cars are equipped with a floor shifter.
