You may still be in the break-in period while the transmission is learning your driving habits - mine was pretty smooth from the factory, though.
9-speed transmission issues
I just bought a 2023 4×4 Frontier SV, when I slow down for a red light or stop sign, and then take off fairly rapidly, it jerks, like the transmission hasn't caught up yet or something, is anyone else experiencing this?

Yes, mine does something similar. It seems to clunk when I return to throttle from the brake, or when I'm coasting, then I accelerate.I just bought a 2023 4×4 Frontier SV, when I slow down for a red light or stop sign, and then take off fairly rapidly, it jerks, like the transmission hasn't caught up yet or something, is anyone else experiencing this?
It doesn't do it all the time. It might do this once every half hour of city driving. It shifts smoothly. Mine almost feels like there's play somewhere in the driveline.
I'm not sure this is the same exact issue..
So, these newer transmissions are smarter in learning how you drive. One of the things is that they hold gears longer, especially on inclines. The clunk you feel is the power transfer through to the wheels. Something similar to driving a manual transmission vehicle, or in older automatics and you put the stick manually in 3rd or 2nd gear and accelerated or decelerated while it held that gear.

most new vehicles try to keep in a higher gear than we'd always like, so I think sometimes you'll come to a quick roll/stop and they don't shift to 1st gear right away. It'll be in 2nd or 3rd and take off, then decide it wants to downshift a gear since the load was high
The above... also, some gears require more steps (multiple release/apply) than others. If I recall 4th is the least with only 1 apply and 1 release required... but don't quote me and I'm not sure under what condition.
"new" Ford Rangers do the same. I've experienced it on 2 different ones. Hence why I went with the Frontier with the proven 5 spd auto.
18k miles in and mine still does it if I apply quick and significant throttle right after nearly but not quite coming to a stop.
Just the way it do.

My 2022 Pro-4X does the same thing. Also try this: accelerate to approx 20 mph, shift to N, gradually/smoothly brake to stop. I get an un-nerving loud THUNK from the drive train just as it stops.
Owner's manual tells not to coast in N. It can cause damage to the transmission. A member posted the text from his owner's manual.My 2022 Pro-4X does the same thing.

Does Nissan still use lockup torque converters? Those can also create these sounds and feeling.So, these newer transmissions are smarter in learning how you drive.

The 9 speed is a Mercedes Benz design, licensed by Nissan. It has a torque converter.Does Nissan still use lockup torque converters? Those can also create these sounds and feeling.
I don’t believe going a couple hundred feet in neutral is going to hurt anything. i’m sure the intent of the manual statement is using neutral on long downhill grades.
I will say to have a caveat like that buried deep in the manual is absolutely insane, and probably deserves a discussion thread of its own.

Yes, and it is a lockup design. There are in fact two related solenoids and is capable of locking up very early.skiddboot said:

I hope your joking. Virtually every vehicle made these days uses lock-up converters.Does Nissan still use lockup torque converters? Those can also create these sounds and feeling.
Not applicable IF recall is done.
Right that's why I'm curious who in this thread had that serviced (or not). Seems like a relevant data point per the discussion.Not applicable IF recall is done.
Mine shifts a little rough occasionally. It's a truck with a frame and a solid axle and the trans is probably a little stout compared to the rest of the powertrain so I just kinda shrug it off. Also some have said that after 10K miles or so it gets a bit smoother. I'd rather it start out a little tight and loosen up to "nice" than start out "nice" and just get sloppy.
