2017 Frontier Transmission Issue

Aloha All,

My brand new shiny arctic blue Frontier PRO-4X seems to have curious transmission behavior. Nissan assure me this is normal as they could find no fault messages when plugging in their diagnostic computer. So, here goes...

At normal cruise speeds (40+ mph), when I come to a hill, instead of the transmission changing out of overdrive and staying in 4th gear (which would be quite sufficient to do the job), it jumps from overdrive and straight into 3rd. However, if I switch off the overdrive button before it automatically changes down to 3rd, the rpm increases slightly as expected and the transmission happily stays in 4th gear.

On normal driving, when accelerating from a standstill, the transmission appears to be working fine, changing up as expected till overdrive is engaged.

It is just the down-shifting that seems quite harsh, resulting in the transmission hunting between overdrive and 3rd gear.

Because no fault codes come up on Nissan's diagnostics, they say this is normal. I only have 1,060 miles on the truck!

What do you say?

Thanks in advance for helping me understand what "normal" should be.

chugging or balls to the wall is how my 2014 frontier goes. It is a very odd feeling. OD off helps and applying slightly more pedal pressure coming up to an incline also helps. I also have some long inclines, not extremely steep on the way to work. These I alway turn off OD or else it will go 3 to 4 sometimes hit OD then back to 3 and repeat a few times until the ground levels off. If I get up some speed before and turn the OD off I can make it most of the way up the hill in 4th. It might drop down to 3rd once.

Basically what you are describing is exactly how my 2014 behaves. I found it annoying at first but now I click the OD off without even thinking.
