i have a problem with my pickups clutch. i fill the resevior with fluid and it just dissapears. as if there was a giant leak in the line. but i dont have any external leaks. i do however have fluid that is building up in the bell housing(u can hear it swooshing when i roll the car. which i ve been doing alot.). would this be the slave cylinder, the truck sat for about a year and i was thinking that some seals dried up. the slave cylinder is internal so i want to make sure that its bad before i get a part and open up the tranny

 

If you have one of those little LED penlights, you should be able to see the leak if you look up and inside by the slave cylinder bleeder screw.
