I was wondering if you have any upgrades or do any upgrades to the TR3650 in the newer Mustang. I am looking to put 600+ at the tires and the trans is my main concern. I want to stay with a 5 speed but may be swapping in a 4r70w if I have to many problems with it. Also do you sell a 4r70w that will handle some serious power. Something like FB Performance or Lentech.
