I have an 03 G coupe A/T and was wondering if its a good idea to maybe get a transmission flush soon or should I be good. And one other thing when getting a transmission fliud change is there a noticable feeling or should I say an improvment in shifting. Thanks

 

I drain and fill mine once a year.

But at such high mileage, your plates may already have been prematurely worn from excessive contaminants, and are relying on the contaminants to operate properly. In your case clushing is definitely not a good idea.

Nissan does not recommend flushing, by the way. See attachment.

 

Oh ok right on thanks for the input. One question so then my best bet is too drain it and change it but how much fluid do I put in if I drain it because I read on here when draining transmission fliud all the fluid don't come out jus partial comes out. So about how much quarts will I need you think????

 

2 years ago I did the flush, but differently than what is described in the bulletin. 2 lines were put into the system, one to drain and the other to fill with new fluid. The mechanic turned the car on and let the car do the flush. No solvents were used. He stopped the flush once the tranny fluid changed color and all new fluid was in there (~11 quarts I think).

Some machines force the fluid change and can cause damage, I've read.

Was the technique used by the mechanic incorrect?

 

you should do a service every 30k. nissan doesnt really recommend flushes unless the fluid was never changed and is hella nasty. i had a 03 sedan come in for a slip....had 102k on the original fluid.....put a tranny in it.

 

I changed transmission fluid at 110k and used 12 quarts. By the way, flush is a different term from change.

 

^haha, I did a transmission rebuild at 110k becuase my tranny took a dump on me... be easy on them brothers, it's only a matter of time

 

If the ATF has never been changed, I would not recommend a flush. Start with a drain/refill from the auto trans pan. You should end up draining between 3-4 qts. Then after 5k miles or so, repeat 2-3 more times.

 

Good advice. I believe it to be around 5 quarts though.

 

^Doing 2 drains within 2 weeks I never got 5qts out. I got 3 out the first time then 4 the second time. You'll get 3-4 during a simple drain and fill.

 

That discusses aftermarket flushes.

Does Nissan/Infiniti not offer a factory approved tranny flush?

Is it true that the 03/04s don't have a dipstick?

 

the early models didnt have dipsticks....you can just get a dipstick from a late 04+ if you want one. normally around 3.5 qts gets drained out. so just buy 4 qts oh matic s.

 

i flush my trany at 35 - 40 .. why u waited so long.. i need to do my differential fluid

 

what brand trans fliud should I use for 2005 g35x?
