I use a tremec TKO that has been faceplatted by liberty gears. Its an old school TKO, not a 500 or 600. It has held up to an honest 675hp on nitrous for about 10 passes now and i have 50-75 low 11 second passes, and 25 high ten second passes on the setup. The last 5 passes i made with the car were all within .05 seconds.
Im impressed with that transmission, my car weighs 3350 with me and a full tank of fuel and on motor im over the factory torque rating, so id say its done the job well

I might have written down the wrong number, but I bet at the price it went before I got even the first response here.
