i need to know if there is an aftermarket rear hub for this trans i keep breaking them in my 2006 supercharged mustang or is there a way to strengthen a stock one . i have 650 rwhp or do i need to get a trans that will handle the power?thanks

You will need a different transmission for that horse power.
This thread is 6 years old and if anyone had come up with an idea there would be notices.
The 4R70's would be better.
