Zola, check with VanPelt for a wide selection of parts (Ford Transmission Parts Prices). Transmission rebuilding does require careful disassembly with photo documentation to aid in assembly. A couple of the snap rings are heavy duty so can be difficult, both to remove and install, without proper tools.

I suspect a problem with the internal shift linkage may have allowed overtravel of the synchro hub (7106). You should consider a full rebuild including all bearings, bushings and thrust washers, including those on the countershaft. Pay special attention to the thrust washer positions and thickness. Good luck!

 

I don't see any other way the hub could have gone that far over except that the cover was installed with the shifter fork for 2 - 3 not seated in its groove on the hub. It must have been behind the hub and pushed the hub clean off the synchro assembly.

Easy enough to fix, just throw money at it! Or evaluate your options for a different, better trans like a 5-sp. In your part of the world, there are probably many more types of transmissions to choose from. An Aussie on here adapted some kind of Toyota 5-sp, but had to make his own adapters. It still might be cheaper and easier than shipping parts to Hungary.

 

Thanks for the tips!
As I've said before, I've never had the chance to drive this truck (or any other old truck), so I'm not sure if I'll keep the original drivetrain or not.
Because of that I don't want to sink a lot of money in this trans at the moment.
I've just bought the C2AZ-7124-A synchronizer assembly, hope it will fit, and I'll take extra care with the forks.

Now I have to wait a few weeks for the package to arrive, this is always the hardest part.

 

Be sure to find that missing tooth!

 

Yes, I've got it.

 

I've received the synchronizer assembly so we disassembled the transmission today.
Here's the worn out syncro ring next to the new one:



Unfortunatelly the sync assembly I've ordered is not correct for my application. It's for a different shaft.
However, I can reuse the inner part of the old one and fit it with the new shoes, springs and sync rings.



I've cleaned all the parts and the case, tomorrow will be the big day for reassembly.

 

It appears that was driven a fair amount like that, it must have made a lot of noise! Talk about hard to shift, too!

 

We reassembled the tranny, I wanted to go for a test drive, but the engine doesn't run smoothly.
It's runnig rich, I have no choke, no idle, and nothing happens when I'm adjusting the idle mixture crew.
The struggling never ends.

One thing is sure, we have first and reverse:
