The
transmission case is gravity cast in a no-bake sand mold with multiple, complex
cores. There are two critical features in the transmission case --
- The spline section at the bottom of the internal barrel.
- The flat base plate of the transmission case which
requires numerous bolt holes for attaching the fluid valves.
Both of these features are critical mating surfaces; they
required extensive machining and need to be free of voids and defects.
-> The
spline is the more critical feature. |
