Thinking of doing drain and fill on my transmission
So my car has 75,000 miles. Never flushed or drain and filled the auto transmission before. Was thinking of taking it over to my local dealer to do it. Got quoted $185. But then did some research on here and from the thread history I found that a drain and fill would be better since with that many miles all the particles being flushed wouldn't be good because the tranny is use to it now. Thank goodness for this forum where I can find useful information. So a slow and gradual drain and fill is the way to go. I found matic j auto tranny fluid for $7/quart at performancenissan.com. So let's say with tax and shipping for 4 quarts for a drain/fill it'll be $35. And I heard the time it takes to do the drain and fill is 30 minutes. So I would have been paying $150 for a 30 minute job. I can do this myself or take it to my mechanic as long as the exact amount of fluid put back is the same as taken out.
Is there anything else I'm missing? Suggestions, thoughts, and comments?

One note, if you asked the dealer to full transmission flush including the torque converter.. That includes them taking the pan off, clean the strainer, taking the torque converter off and draining all the fluid out which should total up to 8 or 9 quarts (I think), install the converter, strainer, and seal the pan, and fill the tranny with new fluid which will take time more than 30 minutes of work.. Now what I've mention above will not be clean as taking the converter off and doing the full flush and but it's second best method. Hope this helps.

Hope this helps.

I've talked to both the Infiniti and Nissan dealers in my area and they both do tranny drain/fills. This is simply draining the tranny of fluid and refilling. Neither recommed a full on flush. Just a drain/fill every 30-40K miles. My G had about 60K miles when I finally serviced the tranny. I bought 8 QTs of J-matic for $8 ea from my Nissan dealer. I removed the filler pipe cover, jacked up the car and placed a pan under the tranny, I removed the tranny pan bolt (19mm I believe), and drained the tranny. I brought the car down to a static level to get as much fluid out. After the drain, I put the bolt back in and then measured the fluid that came out. If I remember correctly, it was something like 3 QTs and 80ml. I then poured exactly the same amount into the tranny. A week later, I did a second round. In another 10K miles, I do another round and call it good for 30K miles. The job is really simple. The key is measuring how much fluid comes out because you don't want to overfill the tranny.

I posted this thread the other days

I think this kind of method could get more of the fluid out of the TQ converter and other hydro lines. Comments?

All depends on how long you plan to keep the car. If its going away after warantee (5 years/70K) anyway, then just do what is required to keep it intact. If you want the tranny to last to 150K, then just do the drain/fills every 30K. If you're looking at holding on until the 300K+ potential of this drivetrain, then do the full flush every 30K.
A tranny replacement is $4K, so by that time, it will be about half the value of the car or more. At that point, the car is almost disposable for salvage. Tranny flush is the CHEAPEST insurance you can buy.

Dealerships and transmission specialist make their money from replacements. Why would you recommend a $240 flush or even a pan drain when you can wait and gross $4,000.
Drain and refill seems to work if you start early around 30k and repeat every 30k............just enough [30%] new additives to carry you thru.
The machine flush [uses a thin solvent chemical*] to remove varnish and abrasive clutch products worn off by normal shifting. Unfortunately you must exchange 95% of solventize ATF or you will create problems.
