problems with my trans

I need help I recently built a brush guard and I was "testing" it and now my trans is grinding as I go through the gears but the input shaft is really wobbly anyone know how to rebuild it cause I don't I locked it already

o.O huh well if your input shaft is wobbly sounds like your gonna either have to replace the bearings in the top half of your case or replace the top half of your case depends on the transmission

Well I have a Dana Spicer 6 speed transmission

I'm with Moose. Crack into 'er and assess the damage.

well i tore it apart for the 4th time this week and nothing noticeable from the top but the bull gear was a little locked up like it wouldn't move and so i took one of the washers out of it and it started to move again. so i put it back together and left it in neutral i spun the pully and both the shafts are spinning and i put a set of pliers on both shafts and they continued to spin so i don't know whats wrong with it maybe the shift keys are a little off idk but im about to give up and not work on it and save up for a new trans so if some one could really help me i would be so greatful and maybe it will get me to add to the topic for my mudder project
