Ever since i got this "built trans" I have had issues of it popping out of fourth gear, and i couldn't powershift third or fourth. Well I pulled the trans today and seem to have found my issue (although i think i made it worse). I noticed during the last time to the track that it was making a little more noise than i remembered, then after on last pass it got very difficult to shift lol... FOUND THE ISSUES
All that on low boost
