i have a 1986 f250 with a 400 c6 1345 bg tranfer case. just recently i notice i am having alot of spraying coming from the vent tubing on the transfer case. this is getting all over my floor inside. does anyone know what my problem is and what steps i can follow to fix it. thank you.

 

Did this problem start right after you extended the line into the cab, or is the case shooting out so much fluid that it gets through the holes in the floor? How is it getting in the cab?

 

it started sometimes once i hooked the tranny vac line into my vac tree on the intake, before then i had it hooked to the carb, i also fixed my heater inside my truck and hooked its vac hose to the tree, the speedo cable all of a sudden the speedo started to get real crazy and then only when on the free way then stop move completely, also went 4 wheeling got high center on a tree finally got off the tree and the truck hit the ground real hard coming off. aound all of this i notice a 2 inch crack in the bottom of my transfer case, leaks a little there but not much. i dont have the rubber boot bolted down on the 4x4 shift so fluid just comes all out from around there and runs all over my floor from there. i also notic it does it more on hight speeds. like between 55 75.

 

i checked my tranfer case and its full past the fill plug, but what im not under standing right now is why is my fluid from the transmission keep going into my transfer case and causeing it to have too mauch and not enogh in the transmission. what is causing this. thank you
