Sounds like I have a stripped gear but they all look fine!
I installed a brushless system in my 2wd pede today and before I did it, I split the tranny filled the diff with moly grease and swapped out all the gears for metal ones, ring gear included. On my first run it soumded like I stripped a gear inside the tranny the truck would barely move and I could hear the telltale sound of stripped gears. But when I split the tranny for the second time, all the gears look fine, no chips no nothing! I am at a loss. Has anyone expierienced this? I am out of ideas other than just replacing all the gears.
