Auto transmission jerk or 'hiccup'
Anyone experience a hesitation or hiccup when slowly accelerating? I notice this when I am slowly accelerating from a dead stop... usually in 3rd gear. Its like the transmission wants to shift into 4th, jerks a bit like it is going to, but the RPMs continue a bit higher and then finally shifts. It is definitely a physical 'jerk' kinda thing going on, though not all the time. I have my first dealer maintenance this Thursday (3750 mi) and I want to recreate it for him to see if there is something definitely wrong or just me.
So its off to the dealer this Thursday... and yes I too have suffered from the sun roof trim falling out, the detached tether on the gas cap and the 'peppered' front grill. Of course they will replace the first 2 items. I wish someone would make (after market) our exact grill in either a harder plastic. I have seen a few after market grills for our car, but they really don't do anything for me.
BTW I have found a great Infiniti site that lists most of the recalls/service bulletins on our car...

Mine feels like a "partial lock up" but it's in 1st gear at slight throttle (20% or less) the tranny "hickups" at like 1000-1200 rpms..... then the car goes like normal.
In 1st, I'd think it should be completely smooth up till around 1800 when the stall kicks in.
I tried to show the service manager what it was doing, and he didn't notice anything. But, I couldn't get the car to do it very noticeably when he was in the car.

This is one of those quirks that doesn't seem like it'd be easy to diagnose.

The dealership said my hickup was "normal." I don't really buy it.
A few other twitches that I noticed with the tranny.
1. When braking and coming to a stop, the tranny will downshift from 3rd to 1st at about 5-8mph, this keeps you from stopping smoothly. It's basically the REVERSE of what I'm describing when I accelerate slowly from a start.
2. When I lightly brake (in traffic) at about 40mph then give it part throttle again, the tranny is doing something wierd between 5th and 4th gear sometimes and it'll almost clunk into gear. Like there's slack in the drivetrain.
I dunno. I guess it'll have to get worse for the dealership to do something about it.
