What's wrong with this Maxima? (video)
This is my friend's max...
Notice how it goes from 1st to 2nd back to 1st gear...
It's an Auto with a CAI & a Y-pipe.
Tranny problems?

NOTE: This was filmed at an airport (that's where he works) no traffic...so don't flame.

First off I can start by saying your speedo is way off and damn do I mean way off bro, 2nd the reason why he went from 1st to 2nd to first was because he had no traction and when in 2nd gear it grabbed traction and decided to go back into 1st because of that, with that said the speedo should not be saying 50 in 1st that is way off, and if he is at wot he should be redlining at 6500 it shouldnt be changing gears at 5000rpm, that tells me the guy who installed the guages ****ed up all the needles totally.

Wait First Off like Killer says the speedo is way off second you are not breaking the tires loose and then it shifts back to first NO. There is somethig wrong with the tranny maybe the A/T solenoid or something it's telling the computer for some reason to shift back down because it sensed that the car was not at it's proper speed for second gear. In the video you can see that the 1st gear pull was fine but as soon as it shifted it seems like it went to 3rd then back down to 1st then 2nd 
.....pull the codes something is wrong with the tranny it's obvious .

I tried to drive my car on 1st and 2nd gear. And it goes up to 6500 rpm.
What should I do next??

Basically he had no traction for awhile (hence the tachometer rising very fast), so when it went into 2nd, it was at a lower rpm. It seemed he let off the gas a bit so it could shift into 2nd, then slammed it again, but it was low enough to drop it into 1st again. Everything looks normal, except the speedometer looks off a bit imo. NOTHING is wrong with the transmission, that is normal behavior, some of you didnt pay close enough attention to notice. It was just bad driving that caused that weird result of a shift.

Oh yeah he had no traction all the way to 2nd let off the gas yup that's the power of the Ypipe and CAI he was slamn the gears in his AUTO with 300hp to da wheels. 
Think before you start running your mouth,

How do you know what the conditions of the pavement were? Last I checked if the conditions of a road/airstrip were bad, you could lose traction with only like..."50hp to da wheels y0"...assuming you were going faster than 10 MPH

He obviously let off the throttle a bit since he was losing traction, thats why it didnt goto redline then into 2nd gear.
It puzzles me why you would even doubt this if you watched the video, maybe you have hearing problems?

I didn't here any wheel spin at all I drive an Auto with over 230whp and before that I had basiclly had his same setup I lost traction for a split second not long enough like your saying. In the video you can obviously see that the speedo and tach are way off it may assume that he's flying through revs but he's not it's way off duh.... second 1st gear was smooth all the way to second but for some reason it fell off he had the gas pedal all the way down the computer incorectly shifted then went back to 1st then 2nd. Why do you think he asked us why his tranny was ****#ed for fun no I'm sure he knows when he lets off the gas cmon commen sense...

What it seems that really happened was, he let off the gas a bit after losing some traction, transmission sensed this to shift into a taller gear, while this happened he mashed the gas again after regaining traction. I've done this before, it makes perfect sense. That's how a automatic transmission works, if you let off the gas to, oh lets say 1/2 throttle, it will know to shift into the appropriate gear to accomodate that throttle position.
About him losing traction? Its clearly audible in 1st gear, why else would he be steering so far to the left for that part?
EDIT: Only proves my theory more, he tested this at an airport. Runway im assuming, that's a straight line test, so why would he be steering so much in the beginning? If he had traction, that would have shifted the shadows from the sunlight at a different angle since he'd be turning......

Gas pedal was pushed all the way down. I didint take it off for any second.
I was testing my car again today afternoon. Always same think.
When I drive on D i still shifts at 5600 or less.
Tachometer works well. I ckecked it on 1st and 2nd gear. It cuts ignition at 6500rpm.

Thats the only thing I can think of, cause the speedometer is way off. I know you tested it out, but I still think you should get that checked out.
