    NOTE: Properly support the seal housing to prevent damage to the seal during removal. Damage to the seal will result in an oil leak.
  6. Support the seal housing for the seal removal using two wood blocks of equal thickness. With the wood blocks on a flat surface, position the seal housing and the blocks so that the transmission side of the seal housing is supported across the dowel pin and center bolt holes on both sides of the seal opening.
