whats goin on? well i have an 84 el camino with what i believe has a 700r4. is there an easy way to tighten the lines on the trans, because i think fluid is leaking out, and i always have to add fluid. would the low fluid cause the transmission to make my rpms drop from around 2500 to almost nothing? then i can press the gas and the rpms will go back up and fall back down. thanks for all the info
