Is there a clutch & automated transmission inspection routine that a small fleet owner can do with competence? I want to get under these trucks and know what I'm looking at and what I am looking for. I want to know where to check fluid levels and where to look for clutch wear. Thank you!

[@homervalenzuela6717]

Realice un cambio de clutch todo bien camino de reversa y drive pero ya después no quiso moverse crees que le haga falta una calibración? No me había pasado antes es en este tiempo de clutch
