I meant add to the equation as in add it to the amount of slippage..... I don't know why I worded it that way doesn't really make sense. But yes I agree with you that the higher stall the more slippage and will probably push me more towards running a lockup converter.

As posted earlier in post #14, this chart notes that the CH in an '88 model was behind a 4.3L V6.

ah okay thanks. Idk why but I was looking for all three characters together and skipped right over that one. So basically this trans is not anything to get too excited over. what hard parts do you suggest I replace for this trans to last behind a sbc making about 400hp/tq(I would like to leave room for expansion... maybe a little spray in a future). I know the stator support and sun gear shell is a must. I have also heard that the forward drum can break but I never saw an estimated hp figure on when it will fail. I know ckperformance has a rebuild kit that includes a new forward drum and they rate it for 450hp.

I recommend getting a Billet shafted Forward Drum & using CKs Shift Recal kit w/Billet Servo.
His #24RRK/SS Rebuild kit contains those 3 w/discount.

I'd also use a 10-Vane Rotor kit. The 13-Vane tend to break more easily at higher rpm & pressures.

Depending on how much spray you use you may want to ask about the .555" TV & .400" Low/Reverse boost valves. They can be swapped inplace of the .500" & .300" size which are standard in the Recal kit.

The splines on the OD Carrier & OD Ring Gear are the next weak link, then the Input Shaft.

I have all 4340 Billet parts in my Trans except the Output Shaft, I don't think I'm pushing 800TQ I rollerized my own parts, easy if you have a Lathe.

There was a Suplement to Chris' 2004R Manual but, I don't know if He has anymore or if they're available now. A Member on TB.com asked but, hasn't received an answer.

Thanks for the reply! I was starting to lean more towards the 24RRK/SS rebuild kit after reading about the weakness in the forward drum.

I haven't really been able to reliably drive my car for the past three summers so I don't mind throwing extra money at the good components to make sure it lives and I can really rack up the miles this upcoming summer.

Would you recommend this pump or any others? TH-200 4R Hi-Performance 10 Vane Pump, this is a must for high RPM engines I believe CK in their Street strip trans uses a new GM pump. Also do you think the OD carrier and ring gear will be okay say around 450-500hp? If I spray it I don't think I would go more than 100-150 but then again im sure it will be tempting to not just throw the biggest jet in there and hang on lol. I think Art Carr did a carcraft article and said around 550 these start to fail but of course vehicle weight and tq play a roll on this also. After I put it together I am gonna also find a transmission dyno to run it and make sure everything works good before I put it in the car.

That's a Pump rebuild kit, not a Pump. It's also a little pricey. If the Pump needs rebuilding I recommend buying a rebuilt one. It's not possible to get the clearances right unless you have a Lathe.
CK has reasonably priced HP Pumps. > www.CKPerformance.com

Pump rebuild/upgrade Info starts about 1/4 way down Pg.
ATTENTION!!!! NEW VERSION!! Strengthening The 2004r | TurboBuick.Com

I'd wait on the Billet OD parts. You can buy them later on if needed.
Chris/CK has a Trans Dyno.

Awesome thanks for the heads up on the pump. Ive never had any experience with this stuff so its great to have some guidance. I may just buy a whole new pump from CK that way I don't have to screw around with a used pump and its setup the way the recommend. Plus it comes with the larger boost valve and the heat treated pump stator I will need. Only problem is Im on the other side of the state so I imagine shipping would be a fortune and its probably about a 6hr drive one way. But then again I may not be able to find something local so who knows. I will have to figure that out when the time comes I guess.

If you plan on dual feeding you NEED the billet forward drum.

Here are some links. I have a bunch more that include suppliers that have parts.

I started a project thing on this site and included some pix. I am moving along on my rebuild but my time is limited as is my %. Did you contact David Husek? He is a noted builder full of excellent info.

Not many put much stock in Arts builds anymore. Those Hardened Forward Drums are polished Turds.

Dave is a good source of Parts & Info, also probably cheaper than CK.
Turbo Buick Performance

[zildjian4life218]

Thanks for all the links TexasT. Those will def come in handy when it comes time to order parts.

SSedan I will definitely check out that link also. Hopefully this weekend I can pull the rest of the guts out of the trans and see what else needs to get replaced and is worn etc. Maybe get the case out to get cleaned up so I can have it painted and be reading for assembly whenever that happens.

I work with a fellow that grew up working at the first Art Carr location. He even worked at the second location after Art sold the place to the business investor guy that moved the business to Las Wages area. He has stories about his days there.

[zildjian4life218]

Well I got the transmission all taken apart today and found a couple blued pieces and a broken 1-2 accumulator spring. Any idea what would cause the spring to break? Also the Accumulator plate has some gouges in it im assuming from the broken spring. Should I replace this? I noticed pitting on a bunch of the steels. What causes this? Lastly I noticed some blueing on some hard parts. Can I get some input on if they need to get replaced or not. Looks like the forward clutch housing and the internal overdrive gear.

Thanks everyone!!
