Sounds like a good plan to me. You can get them cheap too. I think the 3.03 synchronized transmissions began for mustangs in 1967. Some VMF members probably have them laying around collecting dust and can't give them away. In your case it would be a nice and easy upgrade unless there's something about such a swap I don't know about.

 

consider this, yes you can swap to the 3.03 trans, if you wish. there is an adapter plate available so you can use the stock bell housing. however if you are going to swap transmissions, go for a T5 instead. you still need an adapter plate, also available, and you still need to change the drive shaft.

the advantage of the T5 is that you get two extra gears, one of them being an overdrive.

 

Would a drive shaft change be required with a 3.03 RAN-S code?:shrug:

 

I actually prefer a 3 speed because it is more similar to the original.

 

Where are you located Toad? Like has been said, some of us have a 3.03 we would give away, me included!

 

Orange County California near LA

 

There is no adapter available to attach the 3.03 to the 64-65 170/200 engine since Mid-County went out of business. However, you can easily install a T5 5-speed, which will give you better performance AND better mileage.

Or you can simply learn to double-clutch, which will cost you $0. That's what I did, when I had my 66 Sprint. Let my Dad drive it when I got it together, and as we were lugging up a hill in 2nd I told him not to downshift, as 1st was non-synchro. He calmly double-clutched, slid it into first, and scooted up the hill. Yasee, when he was a kid transmissions didn't HAVE synchros, in any gear.

 

22GT you say when your Dad was a kid transmissions didn't have synchro in any gear? I'm mainly a Ford guy on older (really old now) cars. The Model A (28-31) was upgraded to have a real transmission rather than the multiple pedal with hand throttle Model T. The Model T trans was 3 speed non synchro. For the 32 Model the Model B was 4 cyl, Model 18 was the first Flathead V8. AFAIK the trans was 3 speed, synchro 2nd and 3rd. The Flathead with several modifications was used from 32-53 models. The transmission internals were pretty much similar 32-53 with change to column shift in 40, open drive in 49 and bell housing changes. Strongest trans was the 39, last floor shift. I would guess Ford wasn't the first to use synchros in automobile transmissions.

 

6 cylinder t5 swapper here. My original driveshaft worked just fine. From what I understand some need to be shortened, some do not.

 

I definitely have no interest in 5 speed transmissions.

I definitely want a 3 speed, I was considering upgrading to syncro on 1st gear, but I didn't know I would need an adapter plate. and i dont want to change the drive-shaft.

im happy with my curent original 3 speed transmission w/o syncro, Except, it leaks from the rear yoke, needs a new yoke and rear bushing. I dont want to disable the car while i rebuild it, so im looking for a simple cheep way to pop in another used 3 speed.

 

Well, you can't directly replace your 2.77 with a 3.03. They simply have nothing in common, not the input shaft, mounting flange, output shaft. Nothing.

You could simply buy a 2.77, already rebuilt, and put it in.

Of course, any decent trans shop could replace the rear seal and bushing without removing the trans. It's a pretty simple job, prob'ly only take a couple hours. Why not do that? Car in the shop one day. If you had the right tools, you could do it yourself.

 

Instead of a adapter, would a 3.03 bell housing off a '68 200 bolt up to toads block? If so I literally have one laying in the floor doing nothing but collecting dust.

 

no. his is an early small bell block, and the top two bolts would not line up with your bell housing. if he had a dual pattern 66 or later block, then it would work.

 

Alright well taking the car to the shop is not an option for me, I am set on doing all the work myself, but I work slow and I wouldn't be surprised if the trans needs more work than I thought.

Ware could I find a cheep used one to swap in while I work on the original?

 

Besides ebay, you might try Midwest Transmission Center; Rebuilt Manual Transmissions Transfer Cases and Parts | High Quality Manual Transmission Transfer Cases. They supposedly do/have HED code rebuilds. I have no idea how inexpensive they may be though. You are providing very narrow constraints for help here. Who knows though? Maybe somebody will pop up who has one they don't need or want and let you have it for song.:shrug:

 

When I was 17 I rebuilt the 2.77 in my first Mustang. Took an afternoon. Even if you do the work yourself, it should be a weekend project. The only consideration might be if you get it apart and discover the gears are trashed. If it is running now, and your only problem is the leak, then the gears are not trashed.

Seriously, if the leak and the worn-out yoke are the only problems, you are looking at a Saturday morning project. Don't even need to remove the trans from the car. Really.

Oh, for some reason the 2.77 slip yoke is often worn out, so no surprise there.

Oh, and My Dad was a kid in the was a couple years too young for WWII, and was what we'd now call "working class". Synchro gears were a feature of nicer cars, that he couldn't afford. Heck, even in my time, we had a huge dump truck (bought off the county when they got new ones) that had no synchros. Miss a shift in that bad boy and the shift lever would break your wrist.

 

Sorry, 22GT, thought you said no cars had synchro back when your Dad was driving. Ya my Dad was working class, walking streets selling books to pay for college. His dad had a country store in Lisle North Dakota (100+ population).

 

thank you everyone for helping,

I think Im going to pull the transmission and rebuild it, absent a replacement showing up someplace.

I have never worked on a transmission so I was afraid I would need to disable the car for a long period of time.

I have seen so many people selling half completed project cars on e-bay, and you never know what life will throw at you so it scares me to dissemble a major component of the car.

but you guys make it seem like a doable project,

 

but you guys make it seem like a doable project,

A straight reconditioning, with no gear replacement, is pretty straightforward. The kit should cost you about $100 or less. This one's a little more, but the photo is perfect.

 

Yup......that's the kit I got.
Unfortunately in addition to worse than shot synchro rings the synchro spacers were beyond shot with only 1/2 of ONE of the three still identifiable.

These do NOT come in the kit and the ones in the photo are the ones I got.
They are not drop in replacements so I had to grind the sides and tops to make them fit but I think they are a vast improvement over the earlier ones made of chintzy formed steel.
If you decide to DIY TAKE PHOTOS paying particular attention to shift fork and gear cluster orientations!

 

looks like I will prefer to pull the transmission so I can replace the syncro clutches at the same time.

Can anyone give a recommendation on ware to get a replacement YOKE?

Should I try to find an original ford old new stock or is a reproduction yoke ok?

 

Finding NOS would be pure, expensive luck.

 

do the synchro rings come in the rebuild kit???

And is there anything else I should plan on replacing while its open???

 

I found this yoke for less than half price, Im just a little unsure if its the right one. It says its for a C4.

That is for the bigger trans. The tubular part and the lugs for the U joint are nearly twice the size of your itty-bitty 2.77 slip yoke. It's cheap because it's an aftermarket part and fits about a spazillion cars, with the 3.03 3-speed, the Ford Design 4-speed, The Warner T10 4-speed, the C4 automatic, and the AOD automatic overdrive. You couldn't get that onto your car with a sledgehammer. Sorry.

 

the dementions on the cheper yoke dose not match the car.

 

This is a good read before you dive into it >>> Falcon/Ranchero 2.77 manual Transmission rebuild start-to-finish Tech! | The H.A.M.B.

 

I ordered the shop manual and i found an online source,
http://www.mustang.org.au/technicals/66/6 - transmission.pdf

 

I pulled the gear box apart and found that the broken part was the retainer snap ring on the output shaft next to the sincro assembly.

I also discovered that the counter shaft rod and needle bearing were worn. I plan to replace those.
