97 GTS Transmission : countershaft stuck

[cyruss]

Hi everyone,

My transmission "broke" on the highway, doing 5th and 6th full throttle acceleration.

I start to disasembled my gearbox and found one broken key of the 5/6 synchro.

As I continue to remove all the internal parts to make a full rebuilt (with upgraded parts), I cannot pull out the countershaft as explained on the service manual.

It is so hard to pull it's look like it is a one piece countershaft ! (like Corvette ??) and not 2 pieces.

But there is no reason that it is not a 2 piece ... so any idea of how I can pull it out or why it got stuck ?

Here are some pictures...

Thank a lot for your Help ...
