evilwater · May 11, 2005

does anyone know if the t5 out of a 88 thunderbird torbo coupe will work in an 88 mustang gt. if not will the internals work if i were to switch them??? i know both are t5's but didnt know if they were completly the same. thanks

You can use the t-bird tranny in the 5.0, but you will need to use a different pilot bearing. Not sure what the part number is or what car it came out of, but I want to say a ford Ranger. I may be way off on that so do a search and you will find what pilot bearing you will need. As for strength the t-bird tranny is weaker than the 5.0 tranny so take it easy on her if you want it to last. I think they are only rated to 230 ft/lbs of torque.

what about using the sincros out of the thunderbird to put into the mustang will any of them fit???

T5 is a T5 lol so i bet they will.. double check that though.. but still i dont think you should put one in it.. be better to find one in the junkyard in some car and grab it.. stronger and made for the car lol

Not true. There is a difference between the 4 cylinder T5 and a V8 world class T5.

They may physicly fit, but they are not the correct ones. World class syncros are made out of kevlar I believe, while non world class trannys use brass syncros.

If you are willing to open up the tranny and change syncros, by all means order new ones! You can get a complete tranny rebuild kit syncros, bearings, and all the odds and ends for about $130 - $150, depending where you buy it from.

If it's out of your 88 GT it's a world class, and if you need a rebuild kit pm me cause i have one with all the odds and ends

Check the tag which is where the bell housing bolts up (I'm pretty sure that's where it is.) It will have a # that starts with 1352- write the # down and go to www.ddperformance and click on "Ford WC Trans ID" to check it. That will tell you what the trans was originally in.

The input shaft is smaller on a 4 banger T-5 . I saw the 2 side by side when I bought mine recently . The diameter is smaller . You could switch out the shafts but it's not cost effective .

You don't need to do that you just get a different sized pilot bearing to make up for the smaller input shaft.
