There isn't a 200R4 out there built to the gills that can stand with a TH400 built the same way. The TH400 is by far the stronger and most reliable of the two transmissions. BUT, it comes at a cost, and that's losing an extra gear. That doesn't mean a 200R4 can't work well and get the job done. I am past the point where I would roll the dice on a 200R4, I would be looking into a 4L80E clapped out with all the bells and whistles or the 6speed transmission/harness and controller out of the Mustang Coyote which can take one hell of a beating in stock form.

Strangely enough, they take the 6r80 6 speed Coyote automatic, remove 2 gears and call it the 4r200 with the same internal gear ratios as our 200’s. The gear spacing works well and and their trans can handle 1000+. Going back a little further CK Performance was doing a lot of work fitting the 4r70w in the GN as another alternative. I will put a 4L80 behind my stage 2 and play with it for awhile.

That’s interesting. I wonder if you can get a manual valve body for that Ford 4r200? I like shifting my own gears.

The car im building right now is a 274 S2. Could I have built a 200 sure. But at what cost $6000+? And still would be a gamble or not last as long. Thats why I had a 80e built for $2500 and wont have to worry about it.

There just aren't many v6 guys that need a trans to hold up to 1000hp which the 200 can these days.guys that need a 400 for 700/800 just dont have the right builder.

Here is some experiences I have with 200 and turbo 400s
Bone stock turbo 400 in a 4200# 1979 caprice with a 396 bb and a 175 shot of nitrous car ran 10.96. Had over 200 1/4 mile passes and tons of street passes and miles.
Second transmission experience was a Basic rebuild with alto red clutches and some minor stuff with a reverse manual valve body and trans brake 1400 dollar transmission, I ran 9.89 @ 138 @ 3450 weight. Lots of street passes and a probably about 50 track passes. Never had a issue. I had that setup for 8 years
Same exact build as what I ran my buddy has in his iroc camaro 383 with a 300 shot of nitrous @ 3100#s it goes 9.19 @ 147
Trans is over 10 years old and he’s has close to 300 1/4 mile passes and probably a couple thousand street miles.
Now onto the 200 I have, it’s fully built billet parts etc, hasn’t missed a beat. Car runs 10.06 @ 135 and weights 3850. It drives perfect damn near stock feeling. I paid around 3500 dollars for the trans. Definitely not the cheap route of the 2 but I will say there are things to take into consideration if going with a 400 that will drive the cost up. You will need a different trans yoke, crossmember, driveshaft cut to length or a new one, shifter, and a few little things I’m sure I’m forgetting. Some of these things you will replace if your making power anyway doesn’t matter what transmission setup you go with. But if you already have these parts upgraded take that into consideration
The pros to a 400 is you can get one built by anyone and parts are readily available, but these 200s need someone with experience and know how to build them to last for power. Also parts are getting harder for the 200s and that’s gonna drive the cost up on rebuilding these units. Pros to the 200 is the overdrive and if you really drive your car there is no replacement for the od.
My overview of it is for a all out drag car go with the 400. For a nice street strip Buick go with a 200 and make sure your builder has experience cause shit gets expensive doing it twice.
