Abstract: A transmission for a dune buggy has a transaxle, a transmission gear assembly, a forward bevel gear, a reverse bevel gear, a counterrotation bevel gear, a sleeve and a gear shifting lever assembly. The transmission gear assembly is mounted around the transaxle and is rotated by a motor in the dune buggy. The forward and reverse bevel gears are mounted rotatably around the transaxle. The forward bevel gear connects to the transmission gear assembly. The counterrotation bevel gear meshes with the forward and reverse bevel gears. The sleeve is mounted securely on the transaxle, slides longitudinally on the transaxle and selectively engages the forward or reverse bevel gears. The gear shifting lever assembly connects to the sleeve. Moving the gear shifting lever moves the sleeve.
