i am in need of a t-5 for my mustang. i am really short on cash so i plan to go to a u-pull-it and see what i can find. i know a thunderbird turdo coupe will work, but what other cars can i look for? are 4 cylinder mustang the same 5-speed? it is just to get it back up and running. i can handle paying 35 for a tranny right now....

Look for a ranger or f150 maybe one of those would work as well.

4 cylinder T5 is different- limited torque handling capacity & a 3.97 first gear. Run it hard and it will quickly come apart.

The pilot bearing is different, use one for a Ford Ranger Diesel from AutoZone Part #14672

Or BCA 202-FF carquest number.. It is a roller bearing one like stock and fits like a glove.

I had many 4 cylinder T-5s in my 83.. and I had one that lasted longer then a V-8 T-5 I had. If you don't beat the living crap out of them, they will do you real good. I loved the 4 cylinder T-5... Like having 4.10s with my 3.08s. Go for it if you can find on! Works great, but I never changed the pilot bearing... I understand it didn't fit right, but never gave me a problem.

The 4 banger tranny will work...I run one. The pilot bearing is 15mm where as the 5.0 is 17mm. I had a bushing machined and hardened and pressed on to the input shaft,This is cheap if you friendly with your machinest. I also have had better luck with the "weaker" 4 cylinder tranny. 10000 miles and still goin with multipule slick lanches at the track running 12.80's in a 3480lbs car. The longest a 5.0 t 5 lasted was 900 miles, and the shortest was 26miles and it was boiling over.

I'd run a 4 cylinder tranny untill you can afford a good tranny.

Check this thing out, I just ordered one

I would highly recommend against the 4 cyl tranny unless you have the input shaft machined not only for diameter but length as well. Undo stress on your crankshaft makes for a real mess. Take it from someone who knows.

there is no length difference,just the input shaft diameter.if you don't change to the correct pilot bearing it can cause vibrations after you get past 40 or 50 mph.i ran my 4cyl t-5 for almost 2 years and never destroyed it.i even an it at the d/s a few times.i finally replaced it with a t-5z but i wouldn't hesitate to use another 4 banger model.

Like I said before. I ran I believe 3 or 4 4 cylinder T5's in mine, and never changed the pilot bearing. I never had any kind of vibration issues.

The 4 cylinder input shaft is infact .230 thousands longer, I have not had a problem with this but maybe someone else has

Shaft size diameter


5.0 = 0.668
2.3 = 0.59


That means the 4-banger input shaft is 0.078" smaller.

Not much, so you can get lucky if you don't change it...but i would since there is a bearing available to use.

If ONEBADPNY has followed his thread, he realizes that the pilot bearing is 2mm(.078 thou) smaller, in terms of clearence this is a MILE .If anyone has run this without making some change to the pilot bearing configuration I would say they are EXTREMELY lucky. However what darthcual and myself are stating is that ONEBADPNY has to be aware the input shaft is .230 thou longer, and that this may or may noy be a problem for him.
