I have a Borg Warner T 10 transmission that I bought thinking it was a wide Ratio . It is a close ratio . Tooth count on the cluster gear is 28 23 19 17 . I tried it in my Pontiac Catalina but !st gear was too high . Also it was noisy and will probably need a small parts kit . It shifted fine . 10 spline input and 16 spline output . I do not want to ship it so local pick up please . Thank you .
