I just recently purchased a 2006 378 peterbilt. It has a c-13 and a 10 speed Eaton transmission. Any of the lower gears meaning 1,3,5,6,8, and 10th are hard to get into gear. It feels as if they don’t go as deep into gear as the upper gears do. Has anyone experienced this? I haven’t tore into yet I plan on doing it this Sunday. Iv been into a couple transmissions but never a 10 speed. Thank you.
