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.
