The current valve body assembly, P/N 29541572, is fully interchangeable with any 1000/2000/2400 Series(TM) production main case. The shift body,
the main body and the separator plate are not interchangeable between the two generations of hardware. The current design incorporates a relocation of
the dowel pin in order to prevent mixing of current and former designs as shown.
Parts Modifications
Passageways and orifices have been added/modified to allow for the implementation of the Modulated Main Pressure feature. Mixing of former P/N
valve body components will not be possible. Relocation of dowel pins and modification of separator plates is not allowed to facilitate the assembly of
former and current components.
