Well, my tranny isnt dead yet but I think it wants to go. I have a 3 speed right now and i want a 4. Where would you guys get something like the 200 4 r (??) (the auto 4 speed?) What are your opinions on it???

I prefer to use the 700R4 - I found it an easier conversion.

I like the 200 4R. It has closer ratios than the 700R4. It seems to be a better trans for performance use. The 200 4R swap is alot like swapping from a th-350 to th-400. As the trans size and mount is about the same

I don't understand how a 700 would be easier to transplant than a 200 in a Th350 equipped car.
Care to explain 81-74CamaroZ28?

Both have the same TV cable setup, the 700 is longer, so requires a driveshaft shortening as well as crossmember modification.

The 200 would only require the crossmember to be modified, no driveshaft mods at all...

Have you done both conversions?....

I would do a 200-4R anyday before a 700 conversion...

By the way,
I've done both, as well as a T56, TH350- Th400 and vice versa... in several types of vehicles..

infbp22,
I prefer a 200 for conversions,
mostly because of the ease of install and interchangeability, and better gear ratios.

thanks...

What would you think I'm looking at price wise? Is it a lot more expensive than a th-350? Where would you get it from?

The REAL Art Carr guy himself!!!

He quoted one for my 496 a couple a years ago that would hold like 650 and they can be made all the way up to like 800hp!!

I have done quite a few of these mods in this generation of Camaro
I have just shortened the drive shaft and used the 350 X-Member moved back one notch. There were no modifications done to the TV cable at all - as long as you got the right bracket that comes with the trans.


I wont put a 2004R in a car - it is against my religion - and warranties - as you can tell - I am not a big fan of the 2004R transmission - it is highly overrated and exploded out of proportion by G-Body fans.

The debate continues. I have run both and currently run a 200. Both the 700 and 200 can be rebuilt to handle more power than most folks will throw at it. Myself, after using both, I prefer the 200. The gear ratio spreads are much nicer. I found the swap much easier than the 700. It fits in the tunnel much much nicer for one. Using a TH400 crossmember makes the swap a snap. Bottom line though whichever one you get will be light years better than a basic 3 speed, especially if you get the lock up converter option. The swap expense is 100% worthwhile.

Here is a link to the tranny gurus who hang out on the Turbo Buick site. The list has their sigs on it so you can look up their profiles and get their emails. For a good 700 or 200 I would talk with Chris at CK Performance, Bruce at PTS, Mike Kurtz at Century, Eric Schertz at Dynotech or Lonnie at Extreme Automotive, just to give you a place to start. All these guys know how to make either or both the 700 or 200 live for a long time. Expect to pay around $1500 or so. Hell, Jake knows a lot of the tricks and most of these guys, ask him to build you one.

70 SS 454 CI Dynoed 650+HP (with old cam) All Aluminium Fuel Injected Small Block 708HP (based on Engine Analyzer) with new cam, 908HP with 200 shot of Nitrous Express go juice. 1208 if I put the big jets in it and want to bust rings.

I'm replacing the TH400 in the Chevelle with a 200-4R.
This is going behind a 505 cubic inch 650+ lb ft of torque thumper so we'll see how strong they are...

The only item in a 200-4R weaker than a 700 is the forward drum, it is the major weak poitn and is a $500 part to buy an aftermarket bada$$ billet version.
Pretty big coin for one drum and shaft assembly, BUT,
On a 700 you will need a $50 sun shell, $100 3-4 clutch update kit, $200 5 pinion planets, etc...

Both trans will need a better 2nd gear band, servo, pump vanes and rings, shift kit, etc..

The 700 will STILL have a weak input drum, the "FIX" for this is still a band-aid and will not hold the pure torque and loading/unloading a hard running car can do.
Pressing a sleeve over the drum where the input shaft comes though isn't doing much....
It's gonna take some very expensive billet hardware to make it stout.

Just my opinion as a part time racing trans builder...
I'm not on par with the Real Art Carr, or Bruce Toelle, or Mike Kurtz, but have learned quite a bit in the last few years building trans for everything from my 12 second ride to Michael's 10 second ride to a 1500 hp monster truck.

The GM part number for "the right bracket" on a Q-jet SBC application would be 14077903.

And the cable would be 25507546.

Is the 200 automatic, or is there an automatic version?

sorry to butt in...........jake would it be ok or not.... to run a lockup type convertor or run a performance convertor like a 2500 stall non lock up with out having the lock up switch installed?

what im after do you have to have the lock up working for this tranny......i have a massive tranny cooler and my stall would be under my cruise rpm in 4th (i will gear accordingly)to help keep the heat down

from what i understand i can hook a switch up to the tranny to turn on the lock up at my demand

what other convertors work with this tranny.............? does it have to be lock up compatiable?

ddeennis,
Yes you CAN run a non-lockup converter or a lockup type without using it, but the cooling becomes critical.

If you (as you mentioned) are below the stall speed of the converter, under load, it will build alot of heat.
Many newer model vehicles may cruise at 1500 rpm and a converter that stalls at 2500+ will generate alot of heat.
if you lock it up it takes care of that.

My suggestion is to use a normally open pressure swith on the 4th gear circuit to lock the converter up in 4th.

So the trans shifts to 4th, the converter locks, and all is good.
If you accelerate and it kicks down, the converter unlocks.
It stays unlocked until it gets pressure in 4th again.
You could also toggle this for manual control but it would otherwise be automatic and only require 1 12V keyed wire to the trans.

WOT shifts with a locked up converter can break parts if you aren't careful so I prefer to only lockup in 4th but it can be done in 3rd and 4th.

infbp22,
When I say 200, I'm speaking of the 200-4R.
The 200 was a light duty trans used before the 200-4R, but the 200-4R is based on the 200.
The 200 is a 3 speed auto.

I put a 200-4R in my 79 Camaro a couple years ago; was using an old TH200. Used the same driveshaft and just drilled the frame to move the x-member back 6" or so.
The trans was out of an 88 Monte SS, I put in a shift kit and ran w/ it; works great though I wish I had the time to rebuild it when I did that (was already rebuilding a th400 at that time for my winter car). Of course I'm not running a 500hp 454 either. Prob have 250-300hp, soon to be 300-350 after putting on my Vortecs...
