So my wife bought an 05 Maxima with a few issues. When we got it the rear motor mount and the transmission mount needed replacing. The trans mount was actually broken. When you go from park to reverse or park to drive or reverse to drive, it bangs and goes into gear very hard. I thought the new mounts would fix this but it has not. Trans shifts smooth under all other driving conditions. A couple of times it has revved kind of high before shifting. Other than that it shifts very smooth.
Fluid level is good although I don't know when it was last changed.
One more thing. When changing the trans mount one of the 2 upper mount bolts was messed up on the end. About 1/2 inch of threads missing. I put it back in but the one bolt would not go in all the way so it still has 1/2 inch to go. It is in the trans pretty good though. Don't know if this could still be the cause or not.

 

Why did you buy a car without having it tested and inspected?


Read the sticky?

These issues were all known issues. My wife practically stole the car so couldn't pass it up.

I have searched but will search some more.

Trans is not scrap, can't be, it shifts while driving too good.

I like to do my own mechanic work and am quite capable. Just haven't dealt with a Nissan since my 89 240SX hatchback

 

replace those 3 solenoids and be done with it, it's in the sticky

 

Based on my own experienced, I have the same issue with my 2002 Maxima SE with 110,000 miles. My mechanic drop the transmission pan (never flush the transmission of maxima)1/4 thick of sludge cover the whole pan including the two magnet, the solenoid is cover with sludge. He spray the solenoid with contact cleaner and let it drain for 30 minutes. Replaced the transmission pan , gasket and the bolts (red loctite on the tip). I used the Amsoil OE Synthetic ATF. After driving it for two days, transhift problems solved.

 

Dude, you are freaking rude. You were rude in your first reply to me and then you edited the reply so I edited my reply to you. Then you turn right around and are rude again. And the links you supplied don't answer my question because I am new to these cars and am unaware of some known issues with the trans or these parts. This is supposed to be a forum, I thought, to help Maxima owners, not trash talk people. Of course its easy to talk trash sitting behind a computer keyboard.

 

Thanks Colt149. Some actual useful information

 

If your trans fluid was never replaced, I suggest 3x drain and fill with driving 5 min apart.
Then do it once a year.

If that doesnt work, you might have to remove and clean those solenoids, or replace with the improved ones.

 

Thanks, from what I have read on here the trans is apparently this cars weak point and I was unaware of this. As a matter of fact, after all my reading I am scared to death now. When I checked the fluid it looked real clean but like I said, I have no idea when if ever it was last changed so I will definitely be doing this.
From all my reading, people seem to have done everything short of exorcism to correct this problem with varying degrees of success. Some spent thousands only to still have the same problem and I definitely cannot do that. One guy dropped his trans pan and said there was lots of sludge and cleaned stuff up with contact cleaner and that corrected his problem. Another guy did everything from aftermarket valve bodies to CPS sensors to mounts to trans coolers to complete trans rebuild only to still have the same problem!!
I work weekends so haven't been able to work on it but I'll be back under it tomorrow and see what I can come up with.

 

Hey Kryogen, How much Matic k would I need to do 3 drain and fills on this car?

 

I did a precautionary drain and fill on my 2006 maxima (49,000 miles) last Saturday. I drained out 5 quarts and then refilled the transmission with 5 quarts. Some people have needed only 3.5 quarts on their refill. My drain bolt was a 10mm hex bolt located on front/bottom side of transmission (Headlight side of vehicle). It was a very easy job. I recommend measuring how much fluid drains out and refill with that exact amount, recheck fluid on transmission fluid dip stick when done. I bought a case (12 quarts) of the Nissan Matic K fluid from the dealership for around $125 dollars. Our Maximas are nice vehicles when they are not acting up. I plan on doing this procedure again in about 10 to 14 days.

 

Have you noticed any improvement 230?

 

buy a case of 12 I would say.

approx 3 quarts per drain for me, did 4 with a case. I dont know why some people get more out of it, depends on the slope maybe, I dont know. When I jack the car, the front is up I guess.

The "transmission" is fine.
The issue is just basically that the fluid ages and never gets replaced and turns into goop and jams the solenoids.
(It never made sense to me that there is no replacement schedule on that fluid, and that there is no filter that you can change).

The first drain and fill I did, the fluid was sooooo black and had blobs of stuff in it.
After the 3rd drain and fill, it was quite a bit nicer.
It just sucks that you cant easily get ALL the fluid out to replace, but that's the way the car is made.

Make sure the transmission is at operating temp before draining.

If you are lucky that might de-gunk your transmission. If it's too late, you might need to clean or replace your solenoids.

 

Thanks, gonna get on this this week ASAP! Maybe the trans gods will be with me.

 

the 6th gen maxima 5 speed maximas are very hard on the fluid. replace it right away. I have had a maxima tranny give me lots of problems with missed shifts, stuck in gear and hard shifting. I was planning on installing the shift kit but was talked out of doing so by the transmission shop. I ended replacing the fluid first and see how it goes. It solved the problems completely. Mind you, this car had only 40k miles.

 

Yes I have noticed a difference. I love getting on the interstate and mashing the gas pedal, barely feeling the shifts from 2nd to 3rd and 3rd to 4th. I did not have shifting problems before but I do notice an improvement at slow speeds as well. I can hardly feel the car downshift from 3rd to 2nd and 2nd to 1st.

I am happy I spent the money on a case of matic K and plan on draining and filling every 15,000 miles to keep this quality of a ride.

I drove my car ontop of the curb in front of my house so only the passenger side wheels were on the curb. The driver's side wheels were still on the street. I am lazy and that is not really a safe idea. The drain plug really is not that hard to access and remove in all honesty, I may just try and drain it next time with the car parked on the street. I will put some cardboard on the ground and then place the collection container on top of the cardboard to keep things clean.

Many owners here on the board have rebuilt the solenoids in the valve body or replaced the valve body assembly to ultimately solve the problem. Hope things work out for you. p.s. kryogen is spot on with his analysis.

 

or maybe not, but at least you will have tried the easy solution.

And, if you end up changing the solenoids after changing the fluid 3-4 times, just re-use what you drain when doing the job after that.

Maybe just filter it through a screen.

I do a drain and fill every spring. 190 000km, no shift issues.

Of course if the solenoids are all gunked, will just changing the fluid solve the issue? I dont know. Maybe not.

 

Hey folks, well I got all the supplies for the trans fluid changes but have not done them yet. After having the rear motor mount replaced and then replacing the trans mount myself, I discovered the other mounts were completely trashed as well, so spent most my wrenching time this week on changing those. I am hoping that all the slamming into gear could have been due to the car still having 2 trashed motor mounts. And I do mean trashed!! The passenger side mount literally fell to pieces when I removed it and the front wasn't much better! So far all seems much better but I haven't driven it for extended periods yet and that seems to be when the problem got worse. Will get to the fluid changes in the next few days and I will keep y'all posted.

 

Yea, let us know. I have the exact same problem as you. That slam into gear after driving it for a while. Thanks

 

Will do.
