This is a Doug Nash Pro Shifted 5 speed race trans. I have not used it since I acquired it from a friend. I was planning on making my car strip only, but plans have changed. The trans ratios are as follows: 3.01 1st, 2.14 2nd, 1.57 3rd, 1.24 4th and 1-1 5th. The input shaft is Mopar size 1 3/16"x 18 spline. There is a rear yoke included with the trans. It also come with a Mr. Gasket Vertigate shifter. It was working well when it came out of the car and it runs through the gears great on the bench.
