Question on 1966 Mustang 3 speed transmission

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.

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.

Mine was in a 70 Maverick. Took me to school too.....hard knocks.

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

Toploader 4 speed transmission parts are still readily available...

Toploader Transmisions is where I got the rebuild ki

for my toploader Parts including new gears and synchros were close to $3000. The owne builds transmission parts for big trucks, and makes toploader part on the side. Big Trans Am Mustang fan
