904 Accumulator Spring

Well from what I can tell, removing it makes no measurable difference, so why would you then? Why not leave it there to do it's job and why risk damage to the belleville spring.

Check out the top right hand of instruction page 14, Transgo tell you to put it back in. That's good enough for me.

Can't answer that but I know it works for me. Did you actually install a blocker rod when you did it or did you just take the spring out? When done properly the accumulator must be blocked from moving. In my 32 yrs. of rebuilding torqueflite's I have not seen even one damaged Belleville spring, even in transmissions that have had a manual valve body that not only eliminated the action of the accumulator but also had the line pressure cranked way up.

You might want to remember this, anytime you post something on a web board it's always possible someone may have a different point of view. You have 2 choices when that happens. Either accept the fact that not everyone in the world agrees with you (I know everyone doesn't agree with me, LOL) and say "ok you have your opinion and I have mine" or get mad and ramble on about things. As for me and this conversation, you do as you wish and I'll do as I wish.

Well, if you know John so well then why not ask him, maybe he can enlighten us. I've got no idea why MP would do that. Maybe they just thought it was a good idea at the time :)

I don't need to ask him because I know. And besides, it's YOU who brought him up, not me. Therefore it'd be YOUR job to locate him and drag him over to tell his side. If you have no idea why MP would do that it sounds like you haven't done all your homework. They did it because they tried it and found it works.
