Converting a t5 bird to a4ld tranny Reply #4 – January 21, 2008, 09:49:19 AM I would not choose to use an A4LD man, but just in case, the connector os for the OD, and the Lockup if I am remembering correctly. I know for sure it's for the 4th gear, and I know that it has 3 terminals in that plug, that I belive are 3-4, lockup, and ground. Its just been so long since I have done one of those, hard to recall. Quote Selected

Even though the '05 and newer Mustang uses a trans that can be traced back to the A4LD, they have been greatly improved upon. Quote Selected

Converting a t5 bird to a4ld tranny Reply #10 – January 23, 2008, 10:16:28 PM The A4LD is different from the Mustang to the TCs... The Stang only uses the EEC to give OD... The Bird trans also has has the lockup converter controlled by the EEC... Reason I know this, I sold my A4LD to a friend for a '88 Mustang, he had to swap the valve bodies and the plug on the transmission to make it work... I assume you know you'll need a automatic EEC...Also you'll need a shorter driveshaft, plus the A4LD cross member and brackets that bolt it to the frame rails.. The std cross member mounting for the T5/AOD C/M cannot be used due to the much longer A4LD... Quote Selected
