Can anyone talk me through the process of draining and filling the transmission fluid on my 2005 titan. Where is the fill/drail located? How much Nissan Tranny fluid do I need to buy? I known I am asking alot, but you guys know a hell of a lot more than I do.
THANKS!!!!

I'd be interested in some information about this too. I took my titan into the dealer yesterday for a leaking axle seal and they want $250 to service the trans and 150 to service the 4x4. Seems like a flush and fill is something i could easily do myself. Any advice would be appreciated. Thanks!

I saw a Nissan bulletin that said not to flush the Titan tranny. All I want to do is a drain and fill.

 

[Smokinnitro]

Always drain and fill never flush!!!

There are two ways to do this. Spill & Fill, and "Poor Mans Flush".

Pressure flushes are bad. this is a safe way to flush.

SPILL & FILL

1. Get drain pan and put it under transmission drain plug.
2. Remove plug and drain tranny fluid.
3.Replace plug after fluid stops draining.
4. add as much fluid as you pulled out. (5-6qts of type J or S)
5. Check fluid level on dipstick and add as needed.

"POOR MANS FLUSH"
This will replace all of the fluid in the tranny.
1. Unhook tranny fluid cooler pressure line and put it into an empty gallon jug. (you might want to add about 2' of fuel tubing to this line so you can see it from the drivers door.)
2. Add 3' of fuel tubing to the nipple that the pressure lint came off of. (this will keep the line from dripping on the floor and also a backup incase you put the wrong one in the gallon jug.)
3.drain the fluid from the bottom of the tranny just like the spill & fill and replace the fluid with clean.
4.start the truck and let the gallon jug fill up, then shut off the truck.
measure the fluid in the jug and replace with the same amount of fresh fluid thru the filler tube.
5. empty the gallon jug.
6. repeat step 4. until clean fluid is seen in the gallon jug.
7. Put the lines back on the cooler.

Notes.
1. this will replace all of the fluid with fresh if you use 12-14 qts.
2. I used a gallon jug because 1 gallon = (Yup) 4 qts. easy math.
3. the fluid gets pumped out pretty quick. 3-5 seconds to fill a gallon jug.
4. no backpressure is generated so it is a good flush technique.
5. you can go to a better fluid (royal purple or amsoil) and get the clean fluid in.


Its not as hard as it sounds.

Hope This Helps

Real good info nightstalker! This should be a "sticky" :cheers:

I did this swap yesturday & it was fairly easy. Had a 50/50 chance of picking the pressure line & I picked the wrong one at 1st. On my 06 it was the line going to the bottom of the cooler, on the drivers side of the truck.

Thanks for the great post on flushing the transmission, if I have already replaced my fluid with (amsoil) at say around 40k. Would it be recommended to do a spill and fill or a flush the next time I am due (100k?).

More importantly, I had a pressure flush done to replace all my fluid at 40k, 72k on it now. Am I going to have problems now because I had the fluid flushed? I watched the service guy do it, clean Amsoil went in, black dirty oil came out. He ran it until the oil coming out was clear. Just wondering why it is so bad to have a flush done?

 

[Nightstalker 6]

personally, I wouldn't change any fluid again until about 75000 on the amsoil you have in there. that would be 112000 on your odometer. when I change the fluid in mine next, I will go back with 12 more qts of royal purple again using the PMF methon. I am of the opinion that you should change it all at the same time.

if you already have 30000 miles on the flush, I think you are prob ok with the problems that could happen with the pressure flush.

hope this helps

Could somebody possibly post a quick pic of which press. line needs to be removed to do this? Also, do you unhook the line from the tranny end or the cooler end?

 

[Mighty Titan]

Also interested in a pic of which line it is.

 

[Nightstalker 6]

I can't get pics right now but of you remove both lines from the "cooler" on the bottom of your tranny, those are the ones you use. IIRC the one on the drivers side is pressure. I could be wrong, thats why i say to extend both lines with fuel line so you can put both into the 1 gallon jug.

 

[BucFanTitan]

Why would both be removed? How will the fluid get out of the Tranny then or back into it?

My exact same thoughts after reading that.

BTW, I did come across this diagram: http://www.titantalk.com/forums/att...d1183825847-diy-trans-flush-how-picture-1.jpg

I just completed my third drain and fill of the pan and was curious about the percentage of old fluid was still remaining. There's probably a calculator somewhere that would show this more accurately but here are the rough numbers I came up with.

I've rounded the total capacity to 12 qt. and the pan to 4 qt. (the last couple of times I got out an extra cup or so, and added the same extra amount back in), but I've basically drained 1/3 of the total capacity each time, and wanted to do this over a period of 6 months or so, before the new stuff becomes old.

• 1st change: drained 4 qt old; added 4 qt new.
  Titan now has 67% old and 33% new, (4 qt of 12 are new).

• 2nd change: drained 4 qt (2.68 qt old, 1.32 qt newish); added 4 qt new.
  Titan now has 44% old and 56% new, (6.68 qt of 12 are new).

• 3rd change: drained 4 qt (1.76 qt old, 2.24 qt newish); added 4 qt new.
  Titan now has 30% old and 70% new, (8.44 qt of 12 are new).

• 4th change: drained 4 qt (1.2 qt old, 2.8 qt newish); added 4 qt new.
  Titan would have 20% old and 80% new, (9.64 qt of 12 are new).

• 5th change: drained 4 qt (0.8 qt old, 3.2 qt newish); added 4 qt new.
  Titan has 13% old and 87% newish, (10.44 qt of 12 are new,). edit planned for this weekend, if I have empty milk jugs ... Done Dec. '10

From here on out, 4 quarts every other motor oil change, and won't worry about the percentages.

 

[BucFanTitan]

you know Nor cal thats not a bad idea. I was thinking about doing that my self. Every time I drain the engine oil. Change the tranny pan. I figure it will not get everything out, but three or four times is a good idea. Plus the manual says flushing the lines only changes aout 30 to 50 percent of the oil. So it shoud be good. Plus most oils say they are compatiable so it should work together and be ok to mix.

Boy that was alot of math you do that in your head??

 

[NorCal 4x4]

Windows' calculator was used ... simple math though.

I went ahead and used Nissan Matic-S, figuring it might be a little bit more compatible with the old Matic-J, but who knows. If I did a full fluid exchange there are other brands I would also consider using.

Can anyone talk me through the process of draining and filling the transmission fluid on my 2005 titan. Where is the fill/drail located? How much Nissan Tranny fluid do I need to buy? I known I am asking alot, but you guys know a hell of a lot more than I do.
THANKS!!!!

Nissan J-Matic $2.97

 

[PRJ]

What are you guys using to measure the exact amount that comes out?

 

[Tights24]

Easy thing to do is get a 5 gallon bucket, pour a gallon of water into it and mark with a sharpie where it comes to. Do this with a few more gallons and you have a graduated container. Of course, you can do this with any kind of container if you don't have the room for a five gallon bucket underneath. just remember, the wider the container, the harder it will be to differentiate between a few ounces at a time, know what I mean? An oil change bucket/drain/fat wide flat pan will be pretty hard to mark an exact gallon amount because they are like 20 inches across and that's a lot of fluid in a 1/8 inch high section. Would probably translate into a 1/2 inch section on a five gallon bucket without actually doing the math to figure out.

Or, drain it into any container you want that's empty and then pour into a gallon jug and start measuring how many times you fill the jug.

Just some thinking our loud for you is all.

ok, so I decide to do a drain and fill on the tranny of my '05 titan as she has reached 100k. First, I check the fluid condition after a couple miles of driving manually shifting through the gears as per the shop manual. Park it level, pull the plug behind the tranny pan and only a small stream comes out for about 20 min and that was it. I ended up with about a 1/2 to 3/4 quart. I had gone to the dealer to pick up some matic J (replaced by matic s) and got 6 quarts as they said I would be refilling with about 5 as did the shop manual. I do have a small seep on the rear main but the levels looked good before I started. Did i not run long enough, or am I that low? what say you?

note: the old fluid still had some color and no smell of burning
