4TSB from FB Performance?

[speED]

Has anyone used a 4TSB? It is a Ford based trans from FB Performance. It's a 3 speed auto with a transbrake & an electric overdrive. It also has interchangable bellhousings to fit different motors. They claim 900+ HP and 700 ft.lbs. torque. Interested because I like the closer gear ratio than traditional transmissions. Standard Gear Ratio:2.40/1.47/1.00/0.67
Optional Gear Ratio:2.84/1.56/1.00/0.70

Anyone have an idea what they sell for?

Why not just go with a 4l80e? it has close to the same gear ratio 2.48/1.48/1.00/.078. And can handle more power. Also that 4TSB for gm engines on their website only comes with a full manual valve body.
Edit: forgot to add jakesperformance has 4l80e's with transbrakes
