Can some please tell me what went wrong here


transmission-
1st-oem
2nd-brand new oem
3rd and 4th- mfactory pro series synchro set(straight cut)
5th-oem

I just finished putting in my brand new oem 2nd gear, took it for a spin.. No leaks every thing went fine.
Later that night.. Did a couple of pulls on the street just to see if everything was working properly, every thing felt good.

Today drove the car to work. Shifter had slight movement upon accelerating I figure I just forgot to tighten the rear motor mount. Come to find out I see the countershaft!! I am so sick to my stomach.

Im just wondering if anybody experienced anything like this..And what couldved caused this.
I did indeed call mfactory and they said that 4th gear tends to pull apart, hense the need of a handcuff. Makes sense.
I Just hope I didn't ruin the gears/shafts.

Please ht help me out !
Thanks in advance
