anybody use the mobil 1 synthetic ATF? any difference?
how many bottles you have to buy?

 

yea i used it i forgot how many bottles i bought the BEST way to do your tranny oil chage is DROP THE PAN ! your ganna see alot of metal deposit from your trany clean it off with brake cleaner , and use the mobil 1 atf youll feel the car shift smoother ! i loved it , i always use mobil 1 !

 

how many miles do you have on your max?

 

im interested in find out how to do this ATF flush. Will stores like autozone take used ATF back? Is there a how to for this flush... and isnt ATF flushes done every 30000 miles?

 

i dont know if its true but i hear that mobil 1 last longer.

 

1) Drain pan then drop the pan and clean shavings off. Reattach pan.
2) Pan will hold around 4.5 qts. Buy 5 qts. Put in 4qts, run car around the block, check level while hot. Add if necessary.
3)I did mine at 25k then again at 30k. Will probably do this at 40k then 60k to keep it fresh...that may be overkill.
4)Yes, autozone will dispose of this in the same bin as the regular oil.

 

Ya everything he said. But with one exception. You need to buy like 11 or 12 quarts. And do a complete atf flush. It makes no sense to mix 5 quarts of brand new Mobil 1 ATF synthetic & mix it with 6 quarts of old non syn ATF. Check the stickies it is very easy to do . Especially if you have another person to help you turn the car off & on during the process.

 

yeap it will take you like 1 hour to do the flush.... I haven't done mine yet but that's what people told me....... Question????? to all...... I know I need to buy a new gasket if I drop the pan... what about the screws....?????

 

my dealer changed mt tranny fluid on 30k miles, i got 40k miles now and i want upgrade my fluid with synthetic for more performance, i ordered tranny cooler too so i wanna be all set, i plan to get a VB in the futere.

can i change my tranny fluid on 45k miles? around there, or is it better to wait until 60k miles?

 

Depends on the age/mileage in the car. My fluid, at 20k, was relatively new so mixing in some synthetic here and 10k miles later keeps it fresh. If I do it every 20k by the time I hit 60k I should have roughly 80% to 90% synthetic.

For me, flushing the whole tranny at 20k didn't make much sense...but it is very easy to do by doing the FAQ. We flushed my wife's 93 Sable with this method (40k on a rebuilt tranny) and it went very smoothly.

 

I would get a new gasket, you don't need new screws. Notice how easy the bolts come out of the pan and DON'T tighten them up to tight because the pan will leak if they are to tight. Why... if they are to tight they will bend the pan and cause it to leak.

 

The pan bolts probably should be replaced when dropping the pan. The factory service manual even says, "do not reuse pan bolts." This is because they have a sealant on them that ruined when the bolts are removed. I have heard of some people reusing them and not having any problem. But I'd rather be safe. I'm not going to risk killing my tranny because I'm too cheap to buy some new pan bolts. That's if you're like most people and don't check the fluid levels/condition on a regular basis.

 

well, i asked my friend about synthetic tranny fluid and told me that its not worth to do it now cuz i already changed it, so its not gonna work. is it true?

 

bump............................................

 

Not gonna work? What does that mean?

It's a fluid. Replace it.

 

61 to 78 in-lb are the torque specs for the pan bolts.

 

If you use synthetic tranny fluid, after using normal tranny fluid, it might crack the seals on the tranny and break them. Thats he told me, i dont know if its true though.............. ????

 

I don't see how he can make a statement like that since all vehicles come out of the factory with normal ATF, then we change out to synthetic. I changed my out at 22k (current 41K) to Mobil1 ATF and have never been happier. If your tranny already has problems, then synthetic ATF will not do you any good until you fix the issues first.

I have no problem with my tranny at all.
I got 40k miles and already changed to normal ATF at the dealer but i want to change to synthetic, i dont know im confused guys......

 

If you have a 2003, you shouldn't have to worry about cracked seals. If you have an 89 w/ 200,000 miles on the tranny, then maybe you should be concerned. I switched the tranny fluid in my old 92 at 106k and then again at 136k miles and it didn't break.

 

I have a 2k3 max, are you sure about that? cuz i want so bad to put synthetic but im afraid too after that i heard.

 

GreekMaxima, I think you are worrying needlessly. I changed out the factory tranny fluid completley on an '01 Max at 44K with about 12 qt's of Pennzoil ATF using the directions in the sticky. At 60K I just drained and refilled the pan once w/@ 4 qt's of Penn again. At 75K I completely changed out the Pennzoil again but replaced it with Mobil 1 ATF. In each case the old fluid was darker than the new I added, but I honestly couldn't tell a bit of difference driving the car. If you like Mobil, go for it!

 

You really think the seals in your tranny are already worn / cracked / damaged after only 2 years and 40,000 miles? I guess Nissan's build quality really has gone down the $hitter.

 

i didnt say that.

 

So then why the worry about switching to synthetic?

 

go look Thread #17

 

We are going in circles. Synthetic tranny fluid doesn't "crack" your tranny seals. Wear and tear cracks your tranny seals and SOMETIMES, if your tranny fluid hasn't been changed at a proper interval, then draining the old fluid and replacing it with new, synthetic fluid will cause a detergent effect where the dirt and sludge holding the cracked seals together is washed away, exposing the rips, which start to leak. So again, I ask you: do you really think that your tranny seals are damaged at 40,000 miles on a 2 year old car??

 

i DID NOT said that i have damaged seals, im asking if they gonna crack when i changed it to synthetic.... IM ASKING

 

The short answer is NO...I can say with 100% certainty that mobil 1 or other popular synthetic ATFs (AMSOIL) will not damage your seals...in fact, they might preserve them (due to the premium additive packages and lower operating temperatures). I have used synthetic ATF since the mid 80's in a variety of applications and have never had a problem...some of these vehicles have 200K on the synthetic ATF and I have never encountered one leak, seep or transmission failure. With all due respect, your friend is misinformed and he is spreading false information...

 

he knows a lot of things for supras but i think he doesnt know anything for our cars.

thank you.!

 

bought 12qts package @ Costco for 14 $ w/taxes to flush my power steering. lol I spent only one bottle
