Re all the posts about correct fluid for the Jatco autoboxes. In another world and another the place the question about correct fluid reared its ugly head.
It transpired that the seals being used were the governing factor for the oil.
Dextron and nil Dextron was the answer.
If the wrong fluid is used then the seals (o-rings) would be degraded, resulting in slight leakage from the units inside the box.
The reason for the fluid being retained in the box is I believe because the convertor holds back the fluid when the box is drained but when in use there is an interchange between the fluid in the box and the convertor.
The correct grade of fluid for hydraulics is a constant source of scratching of heads in most systems and has been the cause of many expensive failures in the marine industry that carries you on holiday across the channel.
