Chevy guys swear by the 700R4, BOP guys tend to prefer the 200-4R. Neither one is particularly strong in stock form. Either can be built to withstand serious HP. The turbo Buick community has found and fixed every weak component in the 200-4R and they regularly live in 9 second Grand Nationals when built appropriately. In stock form I've killed three of them behind stock Olds 307 motors with a pavement-ripping 140 HP. In any case, you must run a really good trans cooler, as the heat really hurts them.

I put one i rebuilt in my 1977 nova last year. It behind a healthy 355. I wanted a overdrive for highway use, but i wanted my low gears and overdrive to. I put in extra clutches. five enstead of four in the forward, eight in direct enstead of six, three in the overrun enstead of two, three in the fourth enstead of two, then i used wide band. You have to put in the bigger valves in the pump for extra preasure. I went over board on my rebuild with all kinds of tricks. I'm now working on a built deep pan with cooling tubes. Once that is done, I'm pulling the tranny back out and putting in a higher stall convertor, large tranny cooler and modified governor in it. Its a toy and i like the fun of it. I'm just about done with the rebuild of a second one. Don't ask me why, like i said, it been fun. Your biggest problem will be the TV cable set up. If you study it and work on it, it will be no problem. If you take short cuts----It will be your biggest NIGHTMARE. I'm running 3.73 posi in a 10 bolt 8.5 corp rear.

I forget to mention why I chose the 200 4r. I have a nova i've owned since new. Someday my children may want it back to original, and they can do that because I didn't have to change the drive shaft. I just moved my crossmember back and It all fit like it was always there. I've never rebuilt a auto tranny before, and it seem simple to me. I used my head and i didn't even buy any extra special tool. You'll love the 200 4r.

I have a 200 4r in my 81 Vette. The trans came out of a 85 El Camino. Found a guy in Spanaway Wa to rebuild it to handle 400+ hp. The 355 sbc might be putting out 375 hp. With the positive preasure valve body and all the upgrade internals this trans has no issues with all the abuse I can thought at it. These transmissions will survive but you gotta spend alittle extra.

I thought about the constant preasure valve body, but heard to much about the harsh shifts. Maybe its something else causing it, not the valve body. I was told by the internet, that the 86-90 200-4r were better, but It's suppose to be because of better oil flow. As long as you up the preasure with the low and intermediate boost valves, stronger line bias spring You should have half your problem solved. The second half would to rebuild the pump to 10 vanes, hardened rings, duel springs, and relieve the front pump seal from blow out. I've done all the work on my nova, from motor to rearend, and I wanted the tranny to be of my own making. lCall it personal pride or what ever. Make sure you spend the extra dollars and you'll be happy.

the pre 85 200r4s are known for the stator stripping and the sun gear shell the vb did give much issues the pump needs updated with a larger boost valves and 10 or 13 vane rotor and a seal retainer the servo can be upgraded i use a older 200 servo on stock 200r4s it helps the 1-2 shift a bit wth out being harsh but a performance one a hp build

I'm glad I stumbled onto this post today. I currently have a stock 86 200r4 behind a mild 350 I recently swapped. Got all the brackets and TV cables put on and adjusted but it shifts really light and at high RPM's.

So I literally been thinking all day if I should rebuild it and add a better TC, and shift kit. Or get a 700

Any opinions? Price, performance, time etc.

all my 200 4r are 86's. I liked them because they had the better updates. The 200 will cost more to rebuild than the 700. It the extra cost of the parts compared to the 700. If you go for the 700, make sure you get the later model, it has more of the updates compared to the early model. Also the net seems to have more information on how to build and upgrade the 200 compared to the 700. Read the net and that should help.

My son in law has a 200 4r in a 39 chevy street rod with a mild 350 in it. It is one of the sweetest highway cars I have been in. While I am not a racer and certainly not a trans tech if I were building a rod or custom that was going to spend time on the highway I would certainly love to have a 200. The shift points seem to be just perfect.

The gearing is superior by far comared to the 700r4. I had an 89 Caprice 305TBI/200r4 with 2.56 rear gear. That car was the greatest highway cruiser, it got 29 mpg(CAN) which is abou 24 mpg (US).

200r4 2.74: 1.57: 1.00: 0.67: Reverse=2.07:
700r4: 3.06: 1.62: 1.00: 0.70: reverse=2.29:
1st 4.02: 2nd2.36: 3rd: 1.53: 4th: 1.15: 5th: 0.85: 6th: 0.67

The 2.74:1 1st gear and 1.57:1 2nd gear allows for less rpm drop on the 1-2 upshift which helps keep the ngine in the pwoer/torque band.
the 1-2 on teh 700r4/4l60/60e/65e/70e has way too much rpm drop onthe 1-2 shift. The newer 6l80e/90e is even worse for rpm drop.

I have to overrev my trucks in 1st gear so that the acceleration doesnt bog when it shifts down into 2nd gear.

I wish the 200r4 had the beefy parts that the 700r4 does along with teh superior 200r4 trans.
The best auto trans would be a 4l80e with 200r4 gears.

That 0.67:1 4th gear of the 200r4 is worth about 150 rpm at cruise speeds compared to the 700r4.

What more beefy parts do you feel are necessary for a 2004r? Just about everything that breaks can be had in billet. There are upgraded larger servos, high performance clutches and bands.

Not sure how much beefier parts you need. I didn't use any special billit parts in mine. I'm not full out dragging mine, so i just upped the clutch count, bigger valves, larger relievied pump, larger pan and cooling. As far as i figure from the web from all the guys out there, You are OK at up to 400 hp as long as your not running slicks and hooking it up real hard. I'm at 350 i think, with street tires, and i haven't had a problem. That is why i kind of started building a second one, because i though it wouldn't last. Now i'm finilshing the second one and wrapping it up to put it away. I kicked the HELLo out of it before i put it away last fall, to test it, and it didn't break.

Well the issue I'm having is my 200 isn't performing how I would like behind my 350 and I'm seeing some pretty affordable 700's on the web with everything I'm looking for. So I'm wondering if it'd actually be more cost effective to buy one of the web and hook it up compared to rebuilding the current 200 I have.
