I read an article that said I should use a deep sum pan and convert to use a 4l60 filter cuz when ever you start moving forward all the ATF goes to the back of the pan and uncovers the filter intake. Should I have to worry about this with my daily driver? Or is this drag race only mods?
http://web.archive.org/web/20070319220417/www.drwtransmission.com/thm_200-4r.htm Scroll about 3/4 of the page down and you can read about this problem. I ran into exactly the same situation so I run mine with an extra quart of fluid and have had no problems at all with it.
Yeah that's the very same thing I read. Does this mean if I run a stock pan I just need 1 quart over and the problem is gone?
I have absolutely no idea if my car will be able to do 12s it's gonna be a daily driver not a drag racer. I'll probably just do it to be on the safe side I guess.
Well, that's what I do, but my car isn't capable of mid-12's or better. I have a couple extra pans and hope to find the time to cut them apart and build a deep pan one of these days. I have a trans temp gauge, and running it a quart over hasn't had any adverse affects on the fluid temp or anything else that I can tell.
My tranny builder says not needed. Not a big name but he built mine and it is living behind a Procharged 455. He explained a little bit about the shape of the stock pan and how it is designed to prevent the problems described. Also said that many people do not install the stock filter correctly. If you are going to do a deep pan the Hughes has the shape that most closely mimicks the stock pan. In my case we may be reaching the point of needing a non stock pan.
I'll have to think it over. Those pans are crazy expensive. And I don't plan on running slicks or going to the strip.
Ditto that. My tranny builder is a local guy and he knows his stuff. He never mentioned anything about not racing it and he installed it in my Buick. He's very familiar with the torque a Buick can produce and gave me a 12 month, 12,000 mile warranty.
A local builder, and racer, of GN trannies has it down to a science. He is a brilliant cat with the hardware to prove it. Be sure to check out the pics of his race car. DRW Transmission I modified the deeper pan and added the optional filter on the GN.
So have we reached a conclusion? I'm herring both yes and no. I'm not building a drag car just a decent daily driver.
I read everything that Donnie writes on anything. http://www.drwtransmission.com/ At least the stuff I can understand! You are very lucky to have him as your local guy. If you really need a pan call them. He is the one of the few reasons to go to turbobuick.com Here is the link to start with if you want to study the 200-4r trans. http://www.turbobuick.com/forums/transmission-talk/84598-i-want-everybody-know-exactly-who-who.html As to your question. NO you do not need a deep pan. I ran 12.4's with a stock pan and am still using one behind my supercharged motor. This will probably need to change when I start running it at the track but no need on the street.
With the popularity of these transmissions and the aftermarket industry being what it is, I wonder why no one has come up with a filter for them that has the intake on the bottom like the 700R4 has o No:
On a daily driver or even a spirited driver there's no concern. These trans were standard equipment for many years on many cars without problems. The concern are for people who pull the nose on hard launches. The trans fluid acts the same as the gas and oil and for those guys modifications must be made. If your fuel and oil systems aren't pumping air on a launch than your trans is fine. The reason for the raised filter is to prevent any debris sitting on the bottom of the pan from clogging the filter. Basically you're not entirerly safe either way, it's just a matter of debris or air being the cause of your eventual problems. For a street car though stop worrying about it and just have fun driving.
