What kind of shaft does a Chevrolet 700R4 have?
The 700R4 upon its launch featured a 27 spline input shaft (also found on the THM200C and 2004R transmissions). This input shaft was unable to handle much torque; hence, it was not a surprise when it broke down. Nonetheless, 30 spline shafts were used in Chevrolet small-block V8s 1984, and this helped to give this sturdy gearbox more reliability.
