Guys not sure if anyone has done this but i will be replacing transferbox on my 300tdi autobox. Since i will have access to back of autobox it seems i would have access to the governor valve? After replacing atf oil it held first gear little longer than necessary when cold only maybe two times. Is it worth pulling rear case of autobox and cleaning the governor valve. Is that where it is accessed?. Do the spud shafts between lt230 and autobox wear out?
