Infiniti G35 & 350Z Transmission Drain/Fill

Here is a simple drain & fill procedure that should apply to your G35 and 350Z. If you are worried about doing a complete transmission flush (like me) then a few of these should help you on your way. After completing the initial three drain/fills, I intend to do just one every 30K miles. Go out and DoWitt!

You're awesome i was scared as i had a lot of questions but this was probably the most straight forward easy to understand video ive ever seen the explanations were especially useful 🤙

[@DoWittGarage]

I’m glad you enjoyed it! Thanks for tuning in to DWG 👍🏻

[@pgmurray76]

This is an excellent, complete video. Thank you. Did this yesterday with Idemitsu Type J - NO LONGER MANUFACTURED! I bought the last units from the local supplier. Been driving slowly all day with fresh Matic J and Ultra Platinum 5W30 on this 81F sunny Sunday in October. Such a nice drive and day.

my 05 350z at 114k miles auto trans fluid was prob never changed before, it started shifting so slow and super rough at 3rd and 4th, sometimes wouldnt shift to 5th on the highway. really scary just having 4th gear on a highway going 65+ mph and youre already at 4k rpms, shift slips at 4th gear after cold start, manual mode didnt work and it was just bad after driving on a cold start. i did a drain and fill with 4 1/2 quarts with oem nissan trans fluid from the dealer and shifts are remarkably smoother, 2-3 shift is not as grabby and 5th gear works!! the trans fluid didnt look burnt or black it was brown/pinkish. thanks for the video it helps a lot!

Did your Manual mode ever work again bc mine acts really weird

Love seeing you do a suspension job when you get around to it

[@DoWittGarage]

Valve cover gaskets are coming up in the next month or so, suspension after that! Thanks for watching DWG.

[@treyg35]

actually so helpful gonna do this when I get some oem fluid

[@treyg35]

should you only drain and fill once at a time ?

[@DoWittGarage]

I’d say you COULD drain/fill, drive for a little while, then do another one. But I feel like that would negate the purpose of trying to retain any suspended clutch material in the fluid by replacing too quickly. I personally am waiting between 2,500-5,000 miles between these first three, then every 30k after. Thanks for watching DWG!

I have a question thers any filter to change on this type of transmission

[@DoWittGarage]

​@@jrdiaz4032 good question! There are none. This transmission has a metal filter screen that is good for life.

[@yardboy3955]

Nice easy to follow video. I didn't know you could use “S” fluid in place of “J” you confirmed it, thanks. I notice your airbag light doesn’t blink, would you be interested in doing a video on how to fix a blinking airbag light, not where you turn the ignition key off and on 4 to 6x’s to reset that doesn’t work. Thanks

[@jackchn23]

Was there a washer on the transmission plug? Did you replace it?

[@NickoClement]

cool, thanks for the video!

[@ivan2340]

You should check fluid level with engine idling

[@DoWittGarage]

Correct, idling and in park while warm.

[@Qkfltpdls777]

1. Did you jack up your car or were you able to drain atf without jacking it up? 2. Did you warm up atf before opening the drain bolt? 3. How much quarts of old atf came out?

[@moisesleon5353]

Man ur awseome thank u very much :)

[@jponz85]

What about using lucas transmission slipping fluid along with a new automatic trans fluid replacement?

[@whalies178]

does the car really have to be completely level to do this, or can i just jack up the front?

[@blessedchicca6393]

How do u keep those head light so clear

[@DoWittGarage]

My uncle refurbished them for me before he sold me the car. He used a Mother's Kit that you can buy from O'Reilly. You wet sand, then buff with a drill. Then, you can ceramic coat the lenses and they won't yellow nearly as quickly. Thank you for watching!

what size is that transmission drain nut? need to do one on mine

[@benchod3576]

I have a 2003 G35 coupe with 87,000 miles on it. It's never had a transmission flush done to it. Would it be wise to do a flush or drain and fill?

[@jorgeespinoza3564]

Question young man do I need to replace the filter in the transmission or just drain or fill will be ok

[@DoWittGarage]

Good question! The transmission has a lifetime filter screen in it. Just a drain and fill will be fine. For reference, mine has almost 220k miles and the transmission has never been opened. Thanks for watching!

I just drained mines today and 5 qt came out is that normal? I have a 2005 g35x

Question is your transmission a closed one

[@Marcotic187]

I have a 2006 FX45 that Im wanting to do a drain and fill. It has the 5 speed, and I was wondering if your Infiniti has the same 5 speed transmission. Thanks. 😊

[@DoWittGarage]

I’m frankly not sure, but I believe the G35 and 350z shared drivetrain with the FX35, thus making them likely different. However, I would suspect the process to be similar.

[@javierleon6756]

Question, I had a shop perform a transmission oil change. I did not know that it had to be done with OEM fluids. I am not sure what they used but I am willing to bet it wasn’t OEM. Car has 58k what should I do?

[@javierleon6756]

Its a G35 coupe

[@DoWittGarage]

Hey there. I am assuming you have an automatic transmission. I would check with the shop and see what oil they used for your swap. Not that other oils cannot be used successfully, but I generally recommend OEM fluid when it comes to transmissions and other high-cost wear items. Your car has such low miles that I would have the fluid replaced with OEM and then complete a fluid drain/fill every 25-30k. Thanks for watching!

[@javierleon6756]

@@DoWittGarage I appreciate the response here. Love your videos BTW. And yes, its a AT. So the shop used LiquiMoly ATF 1800. I checked the website and it is compatible with all vehicles that require Matic-S. I called 3 dealers and keep getting mixed responses. One dealer is recommending a full flush. The other is recommending a drain/refill twice. This will help the aftermarket fluid flush out. While the other is recommending just one drain/refill. I am concerned with a full flsuh which doesn't sound healthy and also concerned with having two different fluid in my transmission with just a drain/refill. I am at a loss and don't know what to do next. I don't mind spending the money to get it done right. It doesn't seem like anyone knows hat right is. I would appreciate your insight!

[@DoWittGarage]

I appreciate you tuning in! LiquiMoly is a high quality product, however, our transmissions are picky about their fluid. Nearly all research I’ve done recommends using only OEM Matic-S. For your situation, the only way to remove all of the old fluid and replace with new is through a full transmission flush, as recommended by one of the dealers you called. One or two drain and fills will only dilute the LiquiMoly and new fluid. Since your transmission only has 58k miles, a flush should be just fine. Then, subsequent drain and fills every 25-30k miles for the life of the car.

[@javierleon6756]

@@DoWittGarage any concerns around doing a flush? I will have the dealer do this ofc. Just want to make sure I dont mess anything up

[@estellaronquillo243]

I have a 04 g35 atoumatic it has 142k miles idk how the past owner took care of it should I do this bc my oil is brown and driving funny

[@DoWittGarage]

I would certainly recommend completing a drain and fill procedure, preferably three spaced between 2,500-10,000 miles. Your transmission fluid should be bright red.

[@squidbill]

If you have nissan matic J fluid already would you just add that just to top it off. If anything i just think mines a little low

[@DoWittGarage]

Does your car currently have matic J in it? I wouldn’t mix the two.

[@Forevertaken0417]

@@DoWittGaragethe two can safely mix

[@carlpatrick9102]

Do you do while engine warm

[@DoWittGarage]

Warm or cold will work. Warm lets the fluid flow better, but you have to be careful not to burn yourself on the exhaust.

[@kvkehoe7972]

What other fluids can be used ???

Matic J and matic S only
