Hi all,

I have a 2001 Infiniti I30T. I purchased it at 34,800 miles last year. I do not know if the previous owner had done any service with the automatic transmission fluid, or the radiator/coolant flush. I will assume the previous ownder did not do those services. The car now has close to 50,000 miles. I don't push the car too hard typically, and drive 75% highway, 25% city. I live in NY, so we have 4 seasons a year. I change oil every 3,000, and rotate tires every 5,000. Other than that, I haven't put much service into the car (did change struts, add new wheels/tires, but those are more "modding").

Question: Do/Should I be concerned about servicing the ATF? I want to prevent problems with the engine in the future. If you guys think I should, I'll probably bring it in tomorrow morning to get the ATF changed/flushed/serviced (whatever it needs, I'm clueless about ATF stuff). Also how about the coolant? What other things should I be servicing at around 50,000 miles?

 

I waited until the 60K interval to service my ATF. I belive that's the interval recommended by the I30 manual. I had the engine coolant flushed and filled at the same time.

 

ATF/MT oil- 30k
Coolant- 30k
Air filter- 15k
fuel filter- 30k
spark plugs-30k
PSF-30k
Brake Fluid-30k
Clutch Fluid-30k
Oil-3k

Now of course most people go double these amounts before replacement, but that is suicide...

 

PSF-30k
Brake Fluid-30k
Clutch Fluid-30k

Is it necessary to change these at 30K interval?

 

i got 85000 and bought it with 71000 what should i do about the atf should i flush it or drain and fill it and with wat????

YES... Or you could be like the average man and run it to 100K... while you are at it, might as well run the engine oil to 15K... what the hell ya know, it is just a car...
