The "kit" referred to replaced the ISH, sealing the space where it entered the case. ISH is inoperable. Sorry I don't know the kits source or how complex it is. The Transmission Unlimited people may have a record but it has been several years. They told it was improbable they would ever rebuild another one but there are no doubt others out there who may also be able to source or build a "kit". Again, ISH must have worked without major loss of oil but I gave up trying to find someone who could (or would) fix it locally and was ready to give up on it.
