Deleting TM 100% isnt a good idea for daily driver and street use in my opinion. I would not go any more than 50% on a stock internal trans and that is actually pushing it. Most people think the resulting "harsher feeling" shifts are a product of less slip/faster shifting, and thus will extend trans life. But if all you've done is delete TM, then the more aggressive feel is due to more engine torque through the shift, and not because the actual shift time nor slip is decreased. A TM delete alone will not decrease wear, but rather increase it. Other things must be changed to decrease shift time and slip. Hence why this thread was made.
