What Lakeville says here is exactly what my mechanic friend recommends. I'm also heard Willwren and others say the same thing.

Dropping the pan and draining the oil isn't going to knock loose any of thes hypothetical dirt particles. You hear horror storries about transmission flushes, changes, and such jobs because usually only people with failing trannys work on them.

This has to be one of the most ridiculous and misinformed topics I've ever read on this forum.

Congratulations on the milestone, guys.

Congradulations on going

That was posted as a general warning to anyone reading this far, that there'* some major BS in this topic, and to take some (or most) of it with a grain of salt.

Well what are your views? You do have the better experience in these things then us. Can u rule some of it out for us then?

JDB, your fluid looks great considering the miles on the car. Not bad.

OSG, a manual 24-qt flush is the most ridiculous method I've ever heard. The sheer waste, cost, and environmental impact are some of the reasons I made that statement.

Everyone else:
I've yet to see a SINGLE Bonneville Trans fail because of a flush on this forum, unless that trans already had some obvious problems. My SSEi has had 4 flushes total, and 2 of them extended the failing life of the trans quite well.

My personal experience is that it'* best to drop the pan and change the filter (along with the 1/3 capacity that drains), then go in for a full flush a month later. That'* the best way to get it right. Selecting the proper flush tool is critical. I go somewhere that has the 'piston type' flusher. My old fluid pushes up on a piston under the power of my own trans pump, and as the piston rises, it forces new fluid into my trans from the opposite side.

(apologies for letting this topic go so far without posting, but I can't read everything every day any more)

Thank you almighty one.

Hope you are not aiming that at me...

If the shoe fits, wear it. My comments above should tell you if it does or not. The misconceptions on this forum about trans flushes need to be put to bed. If you have more or better experience than me, and contradictory advice to mine, speak up. That'* the purpose of this forum.
