  • Noise when accelerating, noise when decelerating
  • Difficult to shift into gear

Noise when accelerating, noise when decelerating
Issues associated within this category are generally associated with the NV-5600 input or pocket bearing malfunction, sixth gear failing, the pilot bearing could also fail.

Difficult to shift into gear
This problem is common in the NV5600, this transmission is more like a large 18 wheeler transmission, double clutching at the right RPM’s is key to resolving this problem. Additionally you might have a Clutch hydraulics issue requiring that you replace these elements.

Grinding when shifting gears
This issue can be excessive wear of Syncro rings as well as excessive bearing wear

Jumping out of gear
This problem may be related to worn syncro rings, syncro sliders, gears and/or shaft movements caused by extreme bearing wear.

Will not shift from gear to gear
Fluid varnish build-up around the shift rail bushing exacerbates this problem. We recommend you to have regular NV-5600 transmission maintence.  NV-5600 transmission transmission fluid is extremely expensive at the dealer, call 901-278-0090 or visit HighGearTransmission.com for the best deals!
