GM 10 SPLINE:
The 10 spline Atlas input was designed to fit only the 4WD version of the SM465 transmission. This output shaft protrudes approximately 2-1/2" from the rear of the transmission. When coupling an Atlas to this transmission, you will need one of our adapter housings, the SM465 gasket, and fasteners to bolt the casting to the transmission (P/N 51-9807). This adapter housing measures 3-1/2" long and is the shortest adapter that we offer for the SM465. The Atlas 2 speed is the only unit available for this transmission. Due to the adapter length and the transmission size, the cable shifters are not recommended for this transmission/transfer case combination.
Atlas 2 Speed: P/N A10
GM 35 SPLINE:
The 35 spline Atlas was designed to fit only the 2WD SM465 transmission. This output shaft must be shortened to a length of 3.5" from the rear of the transmission. This shaft must also be locked into position with a set collar. The SM465 is 12" long and offers a 6.58:1 1st. gear ratio. The Atlas 2 speed is the only unit available for this transmission. Due to the adapter length and the transmission size, the cable shifters are not recommended for this transmission/transfer case combination.
Atlas 2 Speed: P/N A35
