LS trannies are good for 3 things.

1. mileage
2. turbo equipped engines
3. slowing down otherwise stock vtec engines

I remember hearing from an old place i used to go to, this guy blew his LS engine, and got a type R motor, but didnt have enough money for the ITR tranny, so he just bolted it up to his LS tranny. The new engine was significantly slower than his PREVIOUS setup with the LS motor. Those damn LS gears are too tall. Something like he was running high 15s with his LS, and with the new setup it was like higher 15's low 16s....the gears were so tall, it would go out of vtec after a redline shift. if i dont make sense i'm sorry, i just woke up.
