Im buying a hatch and the seller said he thinks its grinding gears. The car is not driveable for other reasons so i cant troubleshoot the tranny. When i pull the motor would the malfunctions be visible when i crack open the tranny? synchros maybe?

 

I would bet its the synchros

 

will the damage be visible and how much/difficult is it to fix?
