For the Texas Speed & Performance 4L60E (1998–2006, 13-pin, 4WD) the input shaft spline count is 300 mm / 30-spline, which is the standard for late LS-based 4L60E transmissions.
What is the spline count? Texas Speed & Performance 4L60E Performance Transmission 4WD - LS 1998-2006 13 Pin - 600RWHP Rated - R-4L60E-4X4
I need to order a torque converter for this trans. Can't find the spline count anywhere.
