I intend on putting a 455 in my car in the future. I have a friend that was giving me a 200 R4 trans. Can this handle a 455 the torque of a BB? More specificly a 69 Toro motor?

 

Thanks for the info. I didn't think so...

 

Built they can but not cheap. Look at the power GN guys are making still using that trans.

BTW its a 200 4R I used to get it wrong all the time too.

 

A couple years ago I got a quote from a Buick guy who builds them and for $1800 he would build one to take something like 500 hp and 600 ft lbs torque. I agree with Richard, but how much $$ do you have to play with. John

 

Thanks for the correction Richard. I was going to take it because he said he had it rebuilt and was giving it to me. Also because of the OD. I'm just trying to measure twice and cut once...I might as well just get a TH400 which can handle it in stock condition.

 

I have on 2004R in my 65 with a strong torque 455...no problems for two years now...stock rebuild on the trans...308 gears...but Im not pushing it real hard either.

 

Was talking to a guy from the uk who swapped the 307 olds (from his 86 cad. brougham )for an early 455. Did nothing to the existing 200 4r or the 7.5" diff. He claims he burnt rubber all over the place and owned the vehicle trouble free for 3 yrs . I doubt he is a B.S. artist but maybe he was just lucky.
From listening to olds guys here and reading further, The general consensus is NO for the 200 4r /455 combo
You say the box has been rebuilt--that could mean anything from standard upwards.--you would need to know the specs n ask someone on here about the upgrade --if any.

coldwar has an amazing economy of verbage.

 

I think 442Scotty has the right idea.
I have a 85 Grand National 2004R in my 455 powered 68 cutlass with a 3.55 posi.
Alright, I'll come clean now (Zero Miles).
But I'm confident this trans can perform under the right circumstances.
Don't plan on running this stock. You'll nuke it.
Modified, however, is a different story.
The GN crowd runs this in 9 sec. quarter miles.... With Slicks!!!
Plan on dumping 2K to build it for a solid 455.

Here's my theory.
Run your car 200-1000 miles / year. Run a TH400. It is bulletproof and who cares about getting 10 mpg or the high RPM's on the highway.
Run your car 3000 miles or more / year. Run a 2004R. You'll enjoy the peaceful and low RPM highway cruise and reasonable gas mileage.
Let's face it. You might as well run a small block on 3.42's if you are going to run a big 455 on 2.56 gears. Run the Big 455 on 3.42's and still drive on the highway like you have a 2.3 rear. Life is good when you have the best of both worlds.

 

It will only be summer mileage, but who knows what that that will be. The 200 4r is free, but I think I will pay for the TH400 and do something I know won't break me in the end.

 

Guess that depends on what you have to pay for the 400. The kit below is as you see $445 . How much to have the kit installed ,maybe someone here has some idea ?? And with the th400 you lose the overdrive
It`s the ol` weigh one agst the other trick.
good luck mike

I'm very interesed in this as well. Mostly interested in cruising and want an overdrive. I have most of the parts to drop in my 455 except tranny. 200 4r sounds like the ticket if I can find a good one to rebuild. Where is this kit from?

 

Try CK Performance.com for a trans ready to go...well know and they have a good rep

 

the kit is from
PRO-BUILT AUTOMATICS
909-795-1876
CALIMESA , CA.

I too am interested in this kit --for me it has to be a kit owing to the fact I have a 200-4r and am too distant to get a fully builkt up trans shipped anyway.

 

heh or do a 400 and a Gear Vendors od, that's what's going in my car.
pricey though... I think I'm gonna pop the 3:50 gears outa the 9 inch and go with somthing in the mid to lower 4's

 

The GV plus TH400 will cost more than a built 200-4R, especially once you factor in the custom driveshaft, crossmember mods, etc.

 

tis true, but I was planning on getting most of that stuff changed anyway. I also like the idea of a six speed auto, but that's just me.
Has anybody had experience with carbon fiber drive shafts? am thinking of running one but don't know if they work on the street, stones and such..

 

was going to build a 200-4r a couple months ago and found a place in new york out of a GN forum that said the kit I needed to hold a 455 would cost me $800
