Well with the talk about the 4L80's has anyone had any experience with the 200r4 in a F-body????

 

It's essentially a 700R4 with a B O P bellhousing. There might be a couple other minor differences, like gearing, valvebody programming.

 

Why would companies take the time to make an adapter bellhousing and everything for the 200r4 when they could just build 7oor4 no adapter??

 

You could also add "design" and "manufacturer".

GM divisions were more autonamous in the days when the 700 and 200-4 were designed. Yeah, they are both 4-sp OD automatics, but so is the Ford AOD. They don't share many parts, however.

 

It's definitely possible. I know there's a guy on LS1Tech that's running a 200-4R in his LS1 and a friend of mine is doing it this year as well.

He's had some problems w/ the swap, so it's not nearly as easy as the TH400 swap. One of the biggest problems he's going to have(hasn't got this far yet), is how to drive the speedo. Pretty much his only alternative is to run an aftermarket box from Dakota Digital($$$) or TCI's T-Com (more $$$).

 

I beleive yank has a kit for this bolt in.

 

Actually, I'm looking into this conversion as we speak for next year. The 200-4R was also used in Monte Carlos, etc and is a direct bolt in in that respect (V8). As for speedo drive I'm sure I ran across someone who sold a pulse generator conversion. And if you check out www.artcarr.com you'll find an awesome deal on an entire extreme duty package (tranny/converter).

 

I wouldnt call it a 700R4 by a long shot. The gearing is actually a major difference and the reason why alot of monte owners prefer the building the 2004R over the 700s. It doesnt have that horrendous drop from first to second, which many have said drops ya right out of your powerband. Thats the standard 700 vs 200 argument tho.

However, what isnt debatable at all is that the 2004R is NOT a BOP only tranny, it's on the L69 in all MCSSs. While the GN BZF tranny is built alot better, the GN sure isnt the only car with the 2004R. Build it like the GN guys build em and you'll be in good shape with this tranny. IMHO,

 

As stated above..... the GN has used this trans with great success. The Monte SS is a direct replacement... except for speedo issues & computer. The 200-4r (not 200r4)was not originally designed to be used behind high HP applications, but has proven to hold up quite well. There are virtually no similarities to the 700r4. the 200 has a 2.78 (3.06 on the 700) first gear, making the drops much closer. Slightly better on the track with proper gearing. The 700 will have a better launch on the street with stock gears. The od is .67 (.7 on the 700) giving better cruise mileage with deep gears.

These trannys are holding over 800hp in some applications (many GN's in the 9's) & would be a good choice if you need the gearing benefits. In ultimate form, both the 200 & 700 are prettly close in strength. If building a 600hp or less engine, there is no need to go to the expense of building a new tranny, just fix what you have.

 

Yep, it's completely different then the TH700R4/4L60/4L60e. It is one of the few GM tranny's that comes with both BOP and Chevy bolt patterns. It's biggest advantage (stock) is that it uses a steel main drum where the 700 uses an aluminum one. It's also supposedly a little lighter. It was used in the '89 TTA, but it never came with a torque arm mount so you'd have to fabricate something.

 

It's too bad the 200 never came in an electronic vehicle like the TH400 did in the early 90s. I think it'd be a very popular swap.

As for a torque arm, you can run a Spohn/Madman/Billingsley that move the forward point off the x-member.
