Question about tranny's

[Tomsriv]

Mine has a 200-4R. The gear ratios are closer so you don't have as big a drop between 1st and 2nd. Also the overdrive is a slightly better ratio. I run mine without a lock-up TC so setting it up is simple. As for 400hp, it can be built to hold it with a few aftermarket parts. If you aren't running slicks you will probably not hook up good enough to break it. I've towed a yard of concrete with my truck and that is pretty hard on the trans as well.
