I have a t5 that is as you read able to handle up to 450 hp. I bought it new about a year ago and drove my car 250 miles and then decided to go and buy a tko instead. I paid $1500 for it brand new and it is full of royal purple syncromax which I will have to empty when shipping. This tranny is made for 87 to 93 fox body. It shifted really nice and is truly a nice tranny. If you want and have any more question for me feel free to call me on my cell at 530-524-1339 or send me a email at tlcluver21@yahoo.com and I promise I will get back to you. This is an awesome tranny shifts very nice. Thanks Justin
