I really suggest you take a video of what is exactly happening, showing the tachometer and the speedometer and any sound the car is making.

I would think you will need that anyways if you want to go after Infiniti!

If you have the lag problem in DS mode then that's definitely an issue. As I said in manual mode I do experience the same lag.

 

Could this issue have something to do with the VVEL? I would think so!

 

YES YES YES!!!! That's me.... except mine is much more pronounced from 1-2... There is a solonoid sticking - I would bet money on it!

I thought the same thing- a video... I will need a 2nd set of hands, but I am going to do exactly that. Unfortunately, it looks like it's going to be a lawsuit to get Infiniti to listen and I'm not sure I have the patience, money or time to persue that option.

And I have over $5k in mods in the vehicle, from FI, an intake an a sub.

This suc!

Report this as a safety related defect to the U.S. Department of Transportation. After a small number of identical complaints, they will open an investigation file. If determined to be a safety related defect they will recommend Infiniti recall all potentially affected vehicles and make all necessary repairs to eliminate the safety related defect. If Infiniti refuses, the DOT will mandate a recall.

 

Why are you downshifting to 1st when you are not stopped? You should not be doing this especially in an automatic. You should only downshift to 2nd. You have more than enough power in 2nd in a turn. The automatic transmission is not going to engage in 1st gear until you are going much slower and the RPMs are down which explains why it is not in gear for 3 to 5 seconds. Don't downshift to first. You should have gotten a 6mt if you wanted to do this. The auto transmission is smart enough to know you shouldn't do this because you will damage the transmission over time hence why it doesn't do it.

Well I just read a little more and it is doing this in DS mode as well so in that mode you are not manually shifting, correct? How fast or slow are you taking the corners? It shouldn't be shifting into 1st in a corner.

 

^ what he said. I never down shift to first with my AT.

 

When, I'm in that manual mode, I downshift to 1st coming to a stop all the time, never had a problem. I'm usually going slow enough where the car doesn't rev above 4K, just enough to entertain the ears.

 

There is also another thing to consider that you might have forgot, you have a BB grounding kit. I doubt the poster has anything. The grounding kit makes a big difference on AT cars. This might explain a little when it comes to your car Red.

 

There is some improvement with the BBGK in both throttle response and shifting, although I don't remember anything as bad as he describes prior to the kit. There were some issues with throttle response which the kit seems to have cured quite well. Definately a worthwile upgrade.

 

I do have the BB grounding kit as a matter of fact... And as for downshifting to 1st, I'm literally doing this at between 1-5mph as I am approaching (and EXPECTING) to come to a complete stop. The problem occurs when that expectation is interrupted by traffic beginning to move again and, instead of a stop, I accelerate. Either this causes the transmission to drop OUT of 1st gear (as I cannot determine if it ever enters 1st as I downshift) or it doesn't ever enter it at all until the 3-5 second lag.

That happens to me at times but I kinda like the surge after the lag...it doesn't seem that bad to me but I haven't crashed yet I do have a technique though...when you know you are about to be in this situation, flip it to d and back to ds really quick.

If you need somebody to back you in a lawsuit or just to confirm your problem with a dealership, pm me and I will say what you need me to say...

 

Dang it lee, create a sig with your mods so I know...

 

Same thing happened to me today... delay was maybe 1 to 2 seconds and then a big burst of power. My thought is that because of the "rev matching" feature or something, the computer gets confused for a second or two before actually dropping into gear. I couldn't get it to duplicate but it definitely happened to me.

P.S. I was in manual mode and rolling up to a stop light and decided to downshift to 1st (never do this normally), light turns green and the car doesn't respond to throttle. Weird but I bet the computer just got temporarily screwed up...

 

Didn't you have ESP in your sig?
