200-4R transmissions and 1982 / 1983 700R4 transmissions have a 27 spline input shaft. Very few early 1984 700R4 transmissions have a 27 spline input shaft. All 4L60E transmissions through 1997 have the same 30 spline input shaft as 1984-1993 700R4 transmissions. 1998-2000 4L60E transmissions may or may not have the same input shaft as a 1984-1993 700R4 transmission.
This torque converter will not work with a LS type motor, except a C5 Corvette will work.
The 1200 and 1400 stall speeds are for Diesel engines.
