74.5 347Z Posted July 13, 2003 Share Posted July 13, 2003 Hi Everyone, I was wondering if any of you can tell me for sure that the trans i have is a world class. I bought a '87 mustang for the motor and tranny for $800 and tonight a friend and I was looking at the tranny when we spotted Tremec written on the gear case and the part number below that is 13-52-065-922 G. It still says Borg-Warner on the tail shaft housing. What looks promising is that the metal tag has the numbers M-7003-Z which match the "Ford Racing Super Duty T-5" part number. Is it too soon for me to start celebrating or should i do more research? Any help you guys can provide will be very appreciated.

74.5 347Z Posted July 20, 2003 Author Share Posted July 20, 2003 I just checked and it does have a little less than three turns in 1st. I got lucky on this deal. Thanks for your input. Quote Link to comment Share on other sites More sharing options...
