I have to assume you mean "What is a Doug Nash 4+3?" If that is the case then I can answer that question. The Doug Nash 4+3 is a transmission that Chevy used in the Corvette from 1984-1988. It is a Borg Warner ST10 gear box with a Doug Nash overdrive unit mounted on the rear of the transmission. It allowed 4 forward gear ratios by shifting the manual ST10 portion of the transmission and an additional 3 forward ratios when the overdrive unit was engaged in gears 2,3 and 4 thus the name 4+3.
