There are lots of really good parts available to make the TF727 take a ton of abuse. To see what's available to make check out this company. www.tcsproducts.com. They make their own hard parts and supply many of the name performance transmission builders in North America. Not inexpensive, but not off shore. They can also provide you with performance/hd parts like friction plates and bands. Good guys and the man to speak to is Paul. Use the 800 number, it's good across North America.
