i got this in today. he told me its good for 8-900 hp and said i should be able to beat it on a daily basis with 550-600 and have no problems. its a th400 with a reverse manual valve body and trans brake. lol i know it could get annoying for street use but so what. ive wanted to run my 700r4 so bad but i got a deal so good on this i couldnt pass it up.
