i bought a converter from the trans parts house and it was suppose to be a non-lockup for a regular 727 but when i got it and tried to use it it wouldnt work, i cant remember if it was a fit issue or if it didnt work but anyways i had to take it back and got tthe right one. make sure you have a lock-up transmission and a lock-up converter but dont try interchanging the 2.
