I'm pretty sure a stocker won't last nor would I try. Local guy is selling them for $850 which seems like a pretty good price.
Thinking it would be nice instead of rebuilding my rebuilt(another story)
T350.

Copied this text,

We have fully rebuilt GM TH2004R with rebuilt torque converter. This transmission is a 4speed automatic w/ a 2000 stall lock-up torque converter. All our transmissions are rebuilt w/ new clutches, clutch steels, bands, throttle valve, .500 boost valve, bushings, torrington bearings, filter, seals, gaskets and updated valves in the control body. We build a shift kit that will give the transmission a fast and firm shift. This will be a great transmission for a street rod or updating your TH350 & TH400 in you street rod. This transmission has a lot of advantages over a TH700R4, It is smaller and will fit in tight frames & bodies, it has a universal bell housing that will fit Chevy, Buick, Oldsmobile, Pontiac, and Cadillac. Having a smaller drive train means you have less roting mass so it does not rob the horse power That a TH350, TH400, TH700R4 will. Do not be fooled these transmissions will take horse power and last. The transmission comes w/ a 24 month or 24,000 mile warranty.

what do you think ?

 

good to know we have a tranny guy on here

 

not sure what your saying ?

 

I do know these things can be built to handle high HP, if built right.

What did they do to the front pump? They were known for failing and were often upgraded from a 7 vane to a 10 vane during any rebuild. I am surprised he did not mention it in his ad.

I assume it has the electrical lockup TC, so that will need to be wired in.

Will he allow the warranty with a 455 in front of it?

 

Good questions, thanks part of the point to this thread would be asking the seller questions like that.

Also be nice to hear from people that have done it.
What works, what doesn't.

 

does the trans have all these goodies ?

If Not ,what extra to get to that stage ??You could even supply him with the xtras you would like added at the build stage.

 

I wonder if you would get the warranty if the guy knew you were putting it behind a BBO engine. If he is fine with it then you might as well give it a try.

 

A few comments, since I've collected the parts to build a 200-4R for just this application.

First, talk to CK Performance. http://www.ckperformance.com/resourc...SMISSIONS.html

They build 200-4Rs to live behind 9 sec turbo Buicks. At a minimum you need the hardened stator shaft and the billet shaft forward clutch drum. The roller bearing thrust bearings are a good upgrade as well. The 7 vs 10 vs 13 vane pump is an ongoing debate, since the greater number of vanes just reduces the pulsing in the oil pressure feed line. If anything, more vanes makes the pump rotor hub weaker, so that's a tradeoff.

 

Joe
pls let us know how it runs and what goodies you are putting in it to handle what torque.

If they are selling it for $850 you can be pretty sure it doesnt have all of the upgrades possible...The rebuild kit they will be using comes with upgraded clutches steels and band but for that price you can bet they didnt upgrade the hard parts...unless...

the tranny came out of a 442, Monte SS or Buick grand national. In which case a lot of the hard parts will be upgraded factory stuff. The trans should have a tag on it which will tell you what it came out of. I did my own with every upgrade I could find...cost me more than $850 just in parts for my rebuild...

 

i think thATS STRANGE TANSMISSION IN GRAHAM...........and hes a good buddy of mine....he is a hot rodder just like the rest of us....

 

Ask the builder the information given by Joe and see what his response is.

 

Yep thats them, I guess I will get on the phone with them when I get a chance. Unless leadfoot is heading over for a cool one soon.
maybe you could mention this thread ?

a little history ...........
bought the Cutlass with a extra (complete,less carb) 70 455 hence my junkyard prep thread. Also 455 in parts, bored, new pistons, arp rod bolts
JM20/22 cam with springs C heads bla bla bla
also a fresh (more on that later) rebuilt T350 HD clutches looser than stock convertor. So the plan was run the JY 455 with the ST 2 spd while I put the hotter 455 together then add the T350.
Well...... as it turns out the fresh T350 was done many, many years ago and is rusted enough it wont even turn over.
Now fix the T350 or run with O/D ?
What to do ?

 

If you are good with tools perhaps you could buy the upgraded hard parts and rebuild the transmission yourself. Automatic transmissions aren't that hard to rebuild, all you need is a clutch pack compressor and various snap ring pliers. You also have to do the work in an area that is SUPER CLEAN!

 

there are several aftermarket companies who build the 2004r for high HP engines. That's been a happening thing for several years now. Surely anyone who's been doing any reading at all or building anything and intouch with motorheads who build any kind of street rods. I posted three magazine articles, three different companies, about 8 months back on here when this topic came up one other time. One shop had an 800 plus hp (blown) El Camino and the 2004r tranny held up great in it. And the companies do sell the internal parts for anyone who does their own rebuilding. The length of the 200 is the same as the th350 and 400 w/ the correct tail, so your stock drive shaft can be used.

 

FWIW I have one in my 72, works great. But I've always been told by good tranny guys that there is not a difference in the quality of parts whether it's out of a GN or an Olds wagon. The main differences are the valve body and governor calibrations, and the 2-3 servo. There are some differences in other springs etc. and the boost valve but again no real differences in "hard parts". The main issue is the front drum/spindle. Need a billet one to handle big torque, hp is a minor issue.

 

i miss spoke I thought you were saying The text info and were a tranny shop
I missed read that part of the post wasnt being a smarty marty.

 

I've had one in my '66 98 for 3 years now and no trouble at all. The multi-fit configuration is a clue to what it came out of originally. They were made in three configurations - Olds BB, Chevy and multi-fit. An additional source of info and transmissions is John Kozak in Richmond, KY. He is a retired GM employee and a straight shooter. He has an ad in JWO every month.

 

Actually, the "Olds BB" configuration is just the standard BOP bellhousing. The dual pattern 200-4R cases are by far the most common. I have pictures of the BOP-only case, which apparently was only made for the first year or so of production. I have heard about but never seen the Chevy-only case.

 

a well built 200r4 will hold up behind a 455 but it wont cost $850 try $2000-$3000 for a stage II tranny with billet parts and a torque converter. the 200r4 is still a great way of going its lighter, you get the overdrive and it doesnt rob as much power as a th400 or 350 a stock 200r4 will work behind a mild small block but not a torque monster like a 455 unless you building a trailer queen

 

Tci was marketing a 700r4 with a high flow set up that makes the tv cable less touchy
has or does anyone have one or seen one a what makes it take less power to run ??

 

ive owned a few grand nationals i spent 900 on a rebuild once and it blew in a week, i than spend 2200 and it was very very strong, i was told that there are 2 kinds a 200r4 and a 2004r i cant remember witch 1 they said was the better grand national trans, the $900 shop said all were the same the expensive shop said grand nationals trans were different and had 2 be built different, the tricky part is the kick down cable i think its called a tcb cable if its not adjusted right your trans will blow in time, i love over drive so i say go for it just make sure the kick down cable is adjusted nice and smooth

 

You might also consider Gear Vendors. I've heard nothing but positive reviews about them, the only problem is it is a bit pricey:

I thought but was not sure, no sweat !

those are sweet ! If money was no issue I'd consider this........

http://www.tciauto.com/Products/TC-%...ions%27-4.aspx

but it is an issue, heck I'm thinking about selling my 49 GMC to help finance the Cutlass. Maybe rebuilding my T350 will be easy and cheap
because it was newly rebuilt. One can hope.

 

Just got off the phone with the guy @ the trans shop. Seemed like a straight shooter. Easy to talk with, told me straight up the 200r4 (as in his ad) was not the trans for me. Money the way it is I'll have him look at my T350.
Nice guy.

 

At least he was honest with you. Keep us posted.

 

Listen to Joe P. He knows what he is talking about.
I also recommend CK Performance
Chris at CK will tell you that special hard parts are necessary at 455 power levels.
I purchased and installed a CK performance billet 2004r last spring behind the 455 in my 68 cutlass convertible.
When I go easy, the trans shifts smoothly.
When I get into it, my car is an animal. No problems except wheel spin.

 

Thanks ! Since my car needs everything, but nothing is really bad. I'll go through a (my?) T350 for now and then do the top, paint, 455, 12 bolt posi. Maybe disc conversion? then after the kids are done with college I'll
go 200R4 or G.V. o/d ? who knows either way that may be years.
