Some vehicles with GM 6L45 and 6L50 transmissions may exhibit no engagement when shifted into Forward or Reverse gears. Under these circumstances, it is common that the manual valve has broken into two pieces forcing the car into the Neutral position. Sonnax standard-sized manual valve assembly 104740-24K addresses this problem with additional improvements.
The shape of the Sonnax manual valve linkage is substantially different than the OE version but functions identically.
