 Borg Warner Transmission ID and Ratio Guide

T-10's come in many different ratios.  It's important to know the particulars of your hot rod's drivetrain before purchasing.

If you intend to run a numerically high rear end gear (4.11 or more) the Close Ratio & Wide Ratio will work properly, although highway driving would be rough with this gear, running Approx. 3100 RPM,  3.73, Approx. 2800 RPM,  3.25, approx. 2500 RPM @ 60 MPH w/ a 27" tall tire.  It's adviseable to use a wide ratio box with less then a 4.10 Ratio.  First gear acceleration is reduced with the close ratio gear box, which is why they're typically run with short gears.

All Borg Warners carry assembly data code
(example: WA1923, W = Warner trans., A = January, 19 = day of month, 2 = production year, 3 = shift 1,2,3).
No I's used in transmission assembly or casting codes.
