Shaft, TH400 Input Heavy Duty
Input shaft failure is a common problem in performance GM TH400 transmissions running with added horsepower. OE and aftermarket shafts simply donât hold up in these conditions, leading to spline twist and shaft breakage.

This shaft is intended for use with aftermarket converters with internal turbine support, and its Forward drum spline is designed to be used with Sonnax heavy duty forward drum 34554-01or other aftermarket drums with compatible 28-tooth spline.
