hey everyone,i had my tranny rebuilt at ammco about 56,000 miles ago and now im leaking trans fluid from the vent tube that runs up the tranny dipstick,it only seaps out untill i go on the highway for a little drive then it leaks out enough to drip out on the ground,it doesnt pour out.the tranny shifts great through all the shift points,could my tranny be over heating? if so does anyone no why?and how to remedy? sorry such a long post,but im trying to be thoruogh.ive had so many problems with this truck,i try to take such good care of it,but every time i fix one thing,something else breaks,i am at a loss,dont no what to do, i really love this rig. thanks to all those who have helped us with it!!!!
