So I was just curious on doing this with my Titan.
Is it something you dont want to do yourself and should take to a professional or is it someone like myself (who has changed the rear and front diff oil, and oil / oil filter in my vehicle) could possibly do?
When you do a "Flush" you drain it then put in 4 or 5 quarts, then drain that correct? Then fill it up with the 11 quarts it holds?
I think its kind of expensive to have someone do this to my vehicle - 180 or so at the dealership.
Im also seeing people talk about different brands (not Nissan Matic J) for this. If I were to take this on what fluid would you suggest?
Thanks for any advice to a novice maintenance person you can give. I do want to learn tho.

I "think" that a flush forces all of the old fluid out and is supposed to clean all of the ports and passages inside the tranny. You could not accomplish this buy just dumping the old out in pouring new in.
The best way to do is to have a dealer with a flush machine. They run some cheap ATF through to flush, then fill it with the J.
To approximate a flush by yourself, you can disconnect and drain through the line (return - I think) from the ATF cooler while filling (as described in the service manual), but I would recommend having it done by a dealer with a flush machine.
the bell housing/torque converter hold a significant amount of fluid, this can not be drained by pulling the pan.
Flushing is done with pressure by a machine at a mechanic's shop. Tires Plus here does it for $100, and they'll change your filter...but they are grease monkeys and I really don't trust them.
Now, if your local mechanic has the time, buy him the parts and even the rtv and a new gasket, and filter, and Nissan tranny fluid to do it...tell him you were gonna do it yourself but you weren't sure on how to flush the thing and you didn't want to have your wife kick your butt when she saw all the tranny fluid in the driveway...and you will, tranny pans don't usually have drain plugs, you have to pull it off full of fluid.
this job best left to pro's...or at least guys in coveralls who've got plenty of speedy dry laying around.
I am only at 45K miles but I think I may be towing more often and I think this is a good idea to keep up to date on. I just like doing things myself If I can because then I look at a lot of other things while doing maintenance on my truck.
Best - Can I have them flush it then add the Matic J myself? Obviously I cant drive without it in so I dont know how I could do that to save some money. I want to save money to do more mods!! :-)
The entire trans holds 9.5 quarts, including the cooler and lines. The pan does have a drain plug, and if you let it drain from this, you will need 4 quarts to fill it back up. So, if you do this you will replace nearly half of the fluid. The only dealer near me that had the flush equipment said it is broken half the time, and a flush is overkill, to just drain and re-fill. He said the fluid is supposed to have a life of 100,000 miles, but he is a Stealer, so that can be taken with a grain of salt. He also said they use 13 quarts of fluid, and flush the four extra quarts through the trans to clean it. This just loosens the materials lodged in the screen, according to him. I have done the drain and re-fill every 25,000 miles, and at 53,000 it has been one of the best transmissions I have ever had, including a Lexus and an Audi in the past. I tow my boat every other weekend also. I sent the fluid from my 52,500 flush to a lubricant testing lab, we will see how much wear metal is in it. I plan on posting when I get the data. I also did the front diff., the transfer case (which had a lot of metal mung on the drain plug when removed), the rear diff. and the engine. All of this was part of my 52,500 service I did last weekend.

I changed all my fluids myself except for tranny and radiator/coolant.....The nissan tech that did my coolant flush also did my 2* advance for 20 bucks...He told me that the tranny on my truck held 12 quarts but they used 16 qts. for flushing to make sure they pushed all the old fluid completely out of tranny.....So 4 qts. were wasted to do a good flush....It cost me 250.00 to have both flushed...
ok, ok...if it's got a drain plug then that changes everything!
Man, I love Nissan...thanks again for doing the smart thing and adding a $2 part that saves us hours of work, even though it doesn't help the factory out at all!
if it's got a drain plug...and the fluid's rated for 100,000 miles....then it does make sense to just go ahead and drain/refill what you can get out of it. In every tranny I've seen, there is a filter that hangs into the bottom of the transmission pan, you would be running new fluid on an old filter... but I guess that's becoming more common, even with oil nowadays.
So the question is if I do the pseudo flush myself - Drain then add 4 qts. I run the engine to get the other parts to flush out the old fluid? I realize this may seem like a dumb question but im just trying to learn as well.
I realize I wouldnt save a ton (Probably 50 bucks or so) but I would get to know my truck a bit more and then I could put the notch of changing my tranny fluid on my small list of accomplishments!
Ill have to pose another question on the coolant when I finish reading the manual on that part and the service manual on how to complete it!
If you remove the drain pan, there is a large black pan inside the transmission that has a screen built into it. There was an old thread with photos of someone who opened it up. At 75,000 I might remove the drain pan and vacuum the screen if there appears to be anything on it. I should have my oil analysis data early next week, so we will see how they pan out.
I had mine done in Dec by a Discount Tire service center. The manager used to be the service manager at the local Nissan dealership in St.Augustine, FL. He said that only a flush is recommended and that the filter IS metal and not changed. It is not recommended to remove the pan.
Total flush was $112 including the fluid. Got a deal on tire rotation and balance also.

Discount tire does Transmission Flushes? Never knew this. I will have to call them up.
