I have a 2001 3500 dodge ram van with a 5.9L in it. It suppose to have a 46re transmission on it. But I not sure if it's been changed. Anyhow I was doing work on it noticed the 3-4 accumulator spring is broken. But I also noticed the accumulator piston is much different then what is shown online. If I look up accumulator piston for a 46re I get a piston that is more idk I guess cone shaped. But mine looks more like an engine piston. It's identical to the one on this video in the thumbnail to the right of this guys hand and yellow spring.
