PBS has developed a sequential shifter section for the Mendeola S4S transmission. The pictures show the patterns that were made to cast the housing and cover. The raw castings are prior to machining. The partially assembled prototype unit is shown on the intermediate housing.

This transmission is a 4 speed with reverse. It is designed to handle up to 600 Bhp.

WHILE THIS SHIFTER WAS DEVELOPED FOR MENDEOLA, AFTER 500 UNITS HE HAS DECIDED TO BUILD IT HIMSELF AND HAS CHANGED THE INTERMEDIATE HOUSING SO OUR SHIFTER WILL LEAVE A GAP THAT OIL WILL RUN OUT OF. WE AT PBS WILL REPAIR ANY OF OUR UNITS REASONABLY
