Question on 1966 Mustang 3 speed transmission

Hi - a friend of mine is looking at buying a 1966 289 V8 Mustang with the 3 speed
Someone is telling him these are not very strong transmissions and to
avoid the car - I thought V8 mustangs used the same unit as most of the other small block fords and that this tranny is pretty strong
I'm not sure if someone is thinking of the English ford transmission that they used with some of the early 6 cylinder cars ( and I think I read somewhere that unit was a 4 speed) which I understand was not a strong tranny
Anyway if someone could clarify on this point that would be appreciated - it is a nice car and it would be too bad for him to miss out on it because of some bad advice
Thanks

Is that a 'green dot' tranny? I have a 66 with that one, and it was trashed when we got the car. I don't know what the PO did to it, but the car would only move in reverse.
I tore it down and found a totally worn out, burnt clutch pack, which I replaced with new parts. I added new reverse and fwd bands, and adjusted them properly. I replaced clutch pack piston seals and shimmed the clutch pack to spec.
Still doesn't go forward. The only part I did not open was the tailshaft assembly. I am a novice, and I was under the impression that there's nothing in there that could cause something like this. So I didn't look in there.
All this time, the reverse works like a champ.
I'm stumped. What I did with the center section of the tranny, was a piece of cake, very easy to do. Just need to know tolerances and have the right parts.

reverse.
I'm thinking he's talking about a manual transmission. If it's an automatic I think you can identify it easily by the pan gasket. Most had C4's.

Ahh, it didn't register with me, never had a car with 3 speed manual, seemed unnatural to me :) The C4 auto that I have is 3 speed too, AFAIK

If you ARE talking about a manual tranny ...
I had at least 3 early Mustangs (including 2 '66s) that were originally equipped with the "3.03" 3 speed. I was very hard on transmissions in my youth. I never had any problems with the 3 speeds. I have heard of someone damaging a shift fork on one. Then again, I did the same on a toploader (4speed) which is a very strong tranny.
The toploader and the B-W T10S are a bolt-in swap for the 3.03, using the stock bellhousing.
I would NOT pass up a deal on a '66 just because it had the 3 speed. Certainly many now have T5s.
Good Luck rd

Hi - sorry for being vague in my initial question - it is the 3 speed stick and not the C4 auto that I am refering to
Thanks for all the helpful replies

I read your initial post and I suspected you were referring to a stick, but wasn't quite sure. Anyway, the early Mustang three speed was not as strong as the toploader or the Borg Warner, but don't let that keep you from buying the car. You could always upgrade to a better tranny and the car would not lose any value.
At one time I owned a '66 with a 200 and a three speed stick. That tranny was WEAK. I remember I tore out second gear in it, but at the time I was too poor to fix it so I just went from 1st to 3rd. Hey, it got me to school.

I had a 67 Mustang with a 3 speed manual, I ran it rather hard and never had a problem. Also if you need to rebuild it it's not too hard. if it's tight it seems to be pretty solid. good luck.

The Ford 3 Speed used in the Mustangs is a grea
transmission. It will take a lot of abuse and come back for more. M first Mustang was a 66 289 3 speed. It never broke or complained. An it had every reason to do so
If your friend picks this Stang up and wants to replace it, go with
five speed. The toploader, if you can find one, will be rea expensive. Ford doesn't offer parts anymore for rebuilding it. Fo what it would cost to obtain a toploader and rebuild it, you coul get a good 5 speed
By the way, I have to 60's Mustangs, a 66 and a 68 Shelby GT 350
Toploaders in both at this time. Everytime I drive the Shelby, I a wanting to put it in 5th gear. I am so use to the 6 speed in m 3000GT VR4

Toploader 4 speed transmission parts are still readily available... http://www.toploadertransmissions.com /
They are much tougher than the T-5 transmissions too...
