4th gen transmission question (automatic)
I have a 99 SE automatic. I have observed that most of the times when I am accelerating hard, at the time 3 - 4 shift, the rpms suddenly go high and then down unlike in other shifts the rpms only go down. Its like the car goes to neutral and then shifts to the 4th. I have read post concerning this a while back and cannot find it (yes I know about the search feature and did use it)
Is this behaviour normal?? If not what should I do?

My 99 SE-L Auto doesn't do this. But I have read a TSB regarding that issue. If your car is still under warranty, tell Nissan about it. You may be entitled to a new VB or Transmission controller.
Bottom line, it's not normal.

Where can I find the TSB?

Actually, it is NORMAL. Every newer automatic car I've driven (include Toyotas) does this, except it is usually under light acceleration, not heavy acceleration like you describe. The reason why there is the slight bump in RPMs during the shift is because the engine retards timing slightly to smooth out the shift. If you don't like this, the VB mod should speed up the shift. But it's really nothing to worry about.

I think it is normal for an automagic. I've got a '98 SE auto and before getting Don's VB Mod I found that when accelerating hard while in 4th causes the tranny to hesitate for a second first before dropping down to 3rd gear. Found this out while trying to pass a Navigator on the freeway a while ago. With the VB Mod the shifting is a little more harsher but faster. 
I'd recommend getting the VB Mod if that shifting behaviour bothers you.

This same exact problem, or i guess it's not a problem, happens to my 98 automatic. i always felt that maybe the gear is slipping, but from what's been said...hopefully it's normal. it only happens when driving normally....when racing or flooring, there's is no lag between the gears. i plan on getting the vb mod soon (actually i ordered it in june from don and i haven't gotten it and have received no response to 2 emails sent this past week 
)....but that's another story. i feel a bit more comfortable now that there are some other people who are experiencing the same thing.

WTF??
no idea what any of you are talking about.. this being normal?? are you all doing crack?
I had this problem 3 weeks ago... Then my 2-3 shift started to do this.. then my car would rev in first gear at a stop and catch and LURCH forward... well this past weekend my Service Engine Soon light came on. The car could barely do 40 without shaking and running at high RPMS.
I checked the diagnostic code (1107) and it said A/T failure, cluth plates, and 4th gear timing was off.
Took my car to Nissan on Monday. They checked it all, and came to the conclusion my transmission was shot. They found metal particles from the clutch plates in my RADIATOR. A whole new tranny was dropped in on wednesday and now the car is great again.
I have a 98 auto with 43k on it. I would recommend you get it checked, don't let it go like i did or you will be sorry and nervous as hell. Luckily it was a mechanical error in the tranny that they said sometimes happens, which is why there is a powertrain warranty up to 60k.

Jason, was this fixed under warranty? If not, how much did it cost you?
