Huh? NV4500 manual transmission fails in the field because of a hydraulic issue? You’re probably saying to yourself “This guys wacked or drinking his lunch if you know what I mean.” There’s nothing hydraulic about a NV4500 5spd manual transmission.This all starts with a 2002 GMC 2500 with a complaint of sticks in fifth gear. Customer states that this has happened to him half a dozen times since the transmission was installed 2000 miles ago and to make matters worse the technician at our shop couldnot duplicate the complaint.
This struck me as very odd complaint for this type of transmission. Over the years there has been a lot issues with fifth gear and the nut that retains it on the shaft but I do not recall that it ever made the transmission stuck in fifth. No fifth, pops out fifth, hard to engage reverse; these are typical complaints of this unit.
