I've been doing alot of looking for a trans that'll really hold up under some power, but that'll stay driveable. I think I'm going to end up with a th400 from Rossler and a GV under/overdrive...the GV I'm not worried about, but does anybody on here have experience with Rossler? They come pretty highly recommended, I asked for input a while back on the Trans board and got "You should buy a Pro-Built 700r4", and I'm hoping for better luck here.

 

Have you investigated what it would take to get the GV into the tunnel? I'd think that's a major hang-up, to say nothing about the torque arm mounting.

If I had enough money to get a GV unit, I'd go with a Probuilt TH200-4R and Spohn crossmember/torque arm ( http://www.spohn.net/product.cfm?productid=1302 ) instead. It'll take lots of power and has a better 1st/2nd gear split than the TH700 or TH400.

I've never heard of Rossler, but that doesn't mean much.
