[@ImZetrro]

With the original transmission?

[@investinjahcoin5029]

As an Infiniti tech myself, I highly recommend changing your transmission fluid if your vehicle has less than like 150k miles. And changing it every 30k or so after that. It’ll help that tranny last longer and stay healthier. If you bring it somewhere ask for a drain and fill. With Nissan matic S. Or you can diy. It’s fairly simple. I always drop the pan and clean the small metal screen inside on my personal car. One fluid I don’t really recommend changing is the transfer case fluid if you are awd. We actually have seen a good chunk of cars that had their transfer case fluid changed, need transfer cases shortly after. Especially higher Milage ones. I believe it has something to do with the clutches breaking down and clogging things or getting stuck in bad places when draining. Only top it off. Too risky in my opinion! Had an older lady’s transfer case go out two weeks ago after she got her fluid changed unfortunately. 😢

[@Marinate305]

Can I do a BG drain and fill on a machine making sure to use the matic S? 2012 Infiniti G37 Coupe RWD 114K miles. If so, how many quarts should I swap?

[@investinjahcoin5029]

@@Marinate305 you could try. I’ve never done it with a machine before. But I’d probably swap half of the total fluid (roughly 6 quarts) at a time.

[@Marinate305]

@@investinjahcoin5029 awesome thanks. It is the PTX machine where you hook the hoses up, one extracts the fluid while the other injects the new fluid back in simultaneously.

Happy to find u guys, thanks for putting these info out. Is there an AFTER MARKET differential bushing available for the 2009 rwd FX35? I am badly in need for it. As INFINITI wants over 2000 dollars to replace this bushing. i live in the ORLANDO area, do you or anyone knows of any good infiniti mech in the area? i would really appreciate a reply regardless. thnx.

[@investinjahcoin5029]

@ honestly I would just put some sort of epoxy inside the blown bushing. I’ve done it on three of my cars with no issues. It’s like a $5 fix instead of a few thousand dollar fix. I’ve used glass sealant or construction adhesive as well. It basically fills up the bushing cavity where the fluid is supposed to be. As long as it’s near the same hardness it’ll feel the same as a new bushing. MotorvateDIY on KZbin has a great video on it Or I would contact z1 motor sports and see if their diff bushing fits your fx. I don’t know off the top of my head

[@chadmiller3770]

Plugs are due at 105k, coils are good til 130k but just replace the plugs and coils at 100k, put denso plugs with Ngk coils.

I have a 2015, and I only have it serviced at the dealer. I work with the same service consultant. 96K miles, and it's been smooth sailing. Though costly, well worth the investment.

[@terrorriizz]

with antifreeze, you can unplug the cabin heater core hose at the return-to-engine hose preferably or use the air bleeder port which is also on the heater core hose if you have one - careful its just plastic and will be brittle with high mileage so maybe get a aftermarket metal one or a new original before trying to open it. youll also need a snug fitting philips screw driver. then get one of those antifreeze fill funnels which makes an extra high fill point that will push the old fluid out within a few minutes and you dont have to bleed air out of the system. takes 2 gallons to get most of the old stuff out. i used a different brand and color antifreeze so that helped me figure out when the old stuff was all cleared out but you can count to 2 gallons if you use the same color. i heard transmission flush machines at dealers use too high pressure and thats what breaks it. you can drain your transmission and fill it at the transmission cooler return hose but you'll have to figure out how to get the new fluid in that return hose which honestly im not sure will even let fluid flow into the transmission, it wont go back into the the direction of the pump, though. if that doesn't work then find a hose that will fit into the drain pan fill port which is like a 1cm wide opening that takes forever to fill. the evils of taking away the transmission dipstick tube - deterring DIYers so you go back to dealer and give them money. and saying its lifetime fluid lol so your trans breaks and you need a new one or a new car. transmission fluids also have a time limit as well as a mileage limit which i hear is 8 years. the original nissan fluid was 12 years old but very low mileage and it was quite brown/oxidated. the transmission now shifts better too. make sure to count how many liters came out and put that much back in. for accidentally filling 87 fuel, put the car in eco mode and even then drive slowly with no hard acceleration attempts to prevent engine damage until you use up the gas tank.

The FX35 2009 is a great vehicle. I know it will last me a lot more years. .it just that i am pissed at INFINI-THIEF about the diff. bushing.

[@chadmiller3770]

Had a valve cover gasket fail at 100k, noticed it when I did the tune up, only one side was bad the other is still ok, my old maxima did the same thing and never had to replace the other side either, the problem was because of the pcv valves were clogged and it blew out the gasket, so always replace the pcv valves at 50k, it's so easy, the dealer wanted 300, lol.

INFINITI IS A RIP OFF. They want over $2000 for replacing the 2009 fx35 DIFFERENTIAL BUSHING. Mine needs replacing, but i can not afford 2000. Is there a after market bushing that will fit this suv? I can you suggest any help. i really is in a jam, as i can not find any definite answers as to which diff bushing i should use for sure> please if u or anyone can assist here i would really appreciate it. i recently moved to the ORLANDO area and is looking to find a good mechanic.

I'm not sure if you said it or not but break fluid also. For Transmission it's recommended to drop the fluid change the fluid. You gotta. Make sure you take it to a mom & pop shop no big chain shops.

Been wanting a q50 for a few years just never went through wit it. For sure getting it pretty used in the 80k-110 mile range what are the price ranges you’d recommend are a good deal in comparison to the mileage it has. Sorry if the question is confusing. I’m also in Michigan if that helps

@SpeedCultureStudios yes we all agree 👍 all the fluids. Lol 😆

[@investinjahcoin5029]

Actually the transfer case takes a special transfer case fluid! Not matic S like the transmission. I also do not recommend changing the fluid on your transfer case. I work at an Infiniti and have seen a bunch of transfer cases go out after changing the fluid. It’s very finicky. Too risky in my opinion. Especially if you have a higher Milage vehicle

Always change the trans fluid on this car. I had to replace my valve body on my 15 q50 and I bet anything it had to do with low pressure or overheating transmission.

No sir. Seems to be no rhyme or reason to valve body failures in these. In fact, people have experienced failure after a fluid change. The recommendation is to not touch the trans fluid if the car is shifting normally.

Every hundred thousand miles you should replace the spark plugs on the 3.7L VQ. Coolant services should performed every 60,000 miles. Transmission service should be performed every 50,000 miles.

[@SpeedCultureStudios]

Spark plugs are supposed to be done every 25k but 50k is probably fine. 100k is WAY too far without a plug change. Please don’t wait 100k to change plugs! I agree with coolant service at 60k. Trans should not be touched before 75k unless it’s shifting weird and even at that should only be a drain and fill, not a full flush service.
